Adaptive capacity is widely held as a key property of resilient and transformative social-ecological systems. However, current knowledge of the term does not yet address key questions of how to operationalize this system condition to address sustainability challenges through research and policy. This paper explores temporal and agency dimensions of adaptive capacity in practice to better understand how system conditions and attributes enable adaptation. An institutional dynamics lens is employed to systemically examine empirical cases of change in urban water management. Comparative analysis of two Australian cities' drought response is conducted using institutional analysis and qualitative system dynamics mapping techniques. The study finds that three...

In this synthesis, we hope to accomplish two things: 1) reflect on how the analysis of the new archaeological cases presented in this special feature adds to previous case studies  by revisiting a set of propositions reported in a 2006 special feature, and 2) reflect on four main ideas that are more specific to the archaeological cases: i) societal choices are influenced by robustness&amp;#8211;vulnerability trade-offs, ii) there is interplay between robustness&amp;#8211;vulnerability trade-offs and robustness&amp;#8211;performance trade-offs, iii) societies often get locked in to particular strategies, and iv)  multiple positive feedbacks escalate the perceived cost of societal change. We then discuss whether these lock-in traps can be prevented or...

Should sustainability and resilience be combined or remain distinct pursuits?
Provedor de dados: 7
Autores: Redman, Charles L; Arizona State University, USA; Charles.Redman@asu.edu.
It has become common for sustainability science and resilience theory to be considered as complementary approaches. Occasionally the terms have been used interchangeably.  Although these two approaches share some working principles and objectives, they also are based on some distinct assumptions about the operation of systems and how we can best guide these systems into the future.  Each approach would benefit from some scholars keeping sustainability science and resilience theory separate and focusing on further developing their distinctiveness and other scholars continuing to explore them in combination. Three areas of research in which following different procedures might be beneficial are whether to prioritize outcomes or system dynamics, how best to...

Resilience to climate change in a cross-scale tourism governance context: a combined quantitative-qualitative network analysis
Provedor de dados: 7
Autores: Luthe, Tobias; University of Applied Sciences Chur, Institute for Tourism and Leisure, Switzerland; University of Freiburg, Centre for Key Qualifications, Germany; info@tobiasluthe.de.
Social systems in mountain regions are exposed to a number of disturbances, such as climate change. Calls for conceptual and practical approaches on how to address climate change have been taken up in the literature. The resilience concept as a comprehensive theory-driven approach to address climate change has only recently increased in importance. Limited research has been undertaken concerning tourism and resilience from a network governance point of view. We analyze tourism supply chain networks with regard to resilience to climate change at the municipal governance scale of three Alpine villages. We compare these with a planned destination management organization (DMO) as a governance entity of the same three municipalities on the regional scale....

Biodiversity conservation continues to be a challenging task for societies worldwide. We undertook a resilience assessment to address the following question: What are the ramifications of social-ecological system dynamics for biodiversity governance of a nationally significant landscape? Resilience assessment offers promise for guiding response strategies, potentially enabling consideration of ecological, social, economic, and governance influences on biodiversity-related activities. Most resilience assessments have, however, struggled to effectively incorporate governance influences. We applied a modified version of the Resilience Alliance workbook approach to explicitly address governance influences at each stage of an assessment of internationally...

Continuity and Change in Social-ecological Systems: the Role of Institutional Resilience
Provedor de dados: 7
Autores: Pahl-Wostl, Claudia; Institute for Environmental Systems Research, University of Osnabrueck; pahl@usf.uni-osnabrueck.de.
In recent years recurring political, economic, and environmental crises require questioning and re-evaluating dominant pathways of human development. However, political and economic frameworks seem to encompass deeply rooted resistance to fundamental changes (e.g., global financial crisis, climate change negotiations). In an effort to repair the system as fast as possible, those paradigms, mechanisms, and structures that led into the crisis are perpetuated. Instead of preserving conventional patterns and focusing on continuity, crises could be used as an opportunity for learning, adapting, and entering onto more sustainable pathways. However, there are different ways not only of arguing for sustainable pathways of development but also of conceptualizing...

Global environmental change requires responses that involve marked or qualitative changes in individuals, institutions, societies, and cultures. Yet, while there has been considerable effort to develop theory about such processes, there has been limited research on practices for facilitating transformative change. We present a novel pathways approach called Three Horizons that helps participants work with complex and intractable problems and uncertain futures. The approach is important for helping groups work with uncertainty while also generating agency in ways not always addressed by existing futures approaches. We explain how the approach uses a simple framework for structured and guided dialogue around different patterns of change by using examples. We...

Exploring Resilience and Transformability of a River Basin in the Face of Socioeconomic and Ecological Crisis: an Example from the Amudarya River Basin, Central Asia
Provedor de dados: 7
Water from the Amudarya River is a vital and strategic resource for semi-arid Uzbekistan because of its heavy reliance on irrigated agriculture. The Uzbek water management regime, however, has proven to be rather reluctant to adapt to changing environmental and socio-political conditions despite recent massive pressures caused by political, environmental, or donor-induced developments in the region.  The aim of this paper is to explore reasons for the low adaptability of the Uzbek water sector and assess implications for the resilience of the Uzbek social-ecological system (SES). By analyzing past losses of resilience as well as first attempts at institutional change in land and water management, we identify drivers as well as structural factors and...

We aimed to contribute to the field of natural resource management (NRM) by introducing an alternative systemic context-based framework for planning, research, and decision making, which we expressed practically in the development of a decision-making &amp;#8220;tool&amp;#8221; or method. This holistic framework was developed in the process of studying a specific catchment area, i.e., the Sand River Catchment, but we have proposed that it can be generalized to studying the complexities of other catchment areas. Using the lens of systemic resilience to think about dynamic and complex environments differently, we have reflected on the development of a systemic framework for understanding water and livelihood security under transformation in postapartheid...

Adaptive Capacity and Traps
Provedor de dados: 7
Autores: Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu; Brock, William A.; University of Wisconsin-Madison; WBrock@ssc.wisc.edu.
Adaptive capacity is the ability of a living system, such as a social&amp;#8211;ecological system, to adjust responses to changing internal demands and external drivers. Although adaptive capacity is a frequent topic of study in the resilience literature, there are few formal models. This paper introduces such a model and uses it to explore adaptive capacity by contrast with the opposite condition, or traps. In a social&amp;#8211;ecological rigidity trap, strong self-reinforcing controls prevent the flexibility needed for adaptation. In the model, too much control erodes adaptive capacity and thereby increases the risk of catastrophic breakdown. In a social&amp;#8211;ecological poverty trap, loose connections prevent the mobilization of ideas and resources...

Power Asymmetries in Small-Scale Fisheries: a Barrier to Governance Transformability?
Provedor de dados: 7
Autores: Crona, Beatrice; Stockholm Resilience Center, Stockholm University, Sweden; beatrice.crona@stockholmresilience.su.se.
Both global and local environmental problems call for the transformation of many contemporary and unsustainable governance approaches. Therefore, recent interest has sprung up around factors that facilitate and hinder societies from transforming governance of natural resources. Using a social-network approach, we study links between informal power structures and knowledge sharing and consensus building. We examine how this interaction may have affected the (in)ability of a community to move from open-access to some form of collective action for resource management. Individuals occupying central positions in a knowledge network can be instrumental in determining which knowledge and interpretation of ecological signals is most dominant. If the same...

Addressing the environmental challenges of the 21st century requires substantial changes to the way modern society views and manages ecosystems. In particular, many authors contend that fundamental transformation of the largely sectoral, expert-centered ecosystem-management institutions of modern, Western societies is needed. There is increasing agreement that more adaptive, integrated, collaborative ecosystem-management approaches, interlinked at multiple scales, would improve society&amp;#8217;s ability to sustainably manage complex social&amp;#8211;ecological systems. Therefore, understanding processes of transformation, and factors that may enable transformation in ecosystem management, has become an active research area. We explore...

Resilience thinking addresses the dynamics and development of complex social&amp;#8211;ecological systems (SES). Three aspects are central: resilience, adaptability and transformability. These aspects interrelate across multiple scales. Resilience in this context is the capacity of a SES to continually change and adapt yet remain within critical thresholds. Adaptability is part of resilience. It represents the capacity to adjust responses to changing external drivers and internal processes and thereby allow for development along the current trajectory (stability domain). Transformability is the capacity to cross thresholds into new development trajectories. Transformational change at smaller scales enables resilience at larger scales. The capacity to...

Research on the barriers and limits to climate change adaptation identifies many factors, but describes few processes whereby adaptation is constrained or may indeed fail to avoid catastrophic losses. It often assumes that barriers are by and large distinct from limits to adaptation. We respond to recent calls for comparative studies that are able to further knowledge about the underlying drivers of barriers and limits to adaptation. We compare six cases from across Australia, including those in alpine areas, rivers, reefs, wetlands, small inland communities, and islands, with the aim of identifying common underlying drivers of barriers and limits to adaptation. We find that the path-dependent nature of the institutions that govern natural resources and...

Generalizable principles for ecosystem stewardship-based management of social-ecological systems: lessons learned from Alaska
Provedor de dados: 7
Autores: Hansen, Winslow D.; Department of Zoology, University of Wisconsin-Madison; whansen3@wisc.edu.
Human pressure could compromise the provision of ecosystem services if we do not implement strategies such as ecosystem stewardship  to foster sustainable trajectories. Barriers to managing systems based on ecosystem stewardship principles are pervasive, including institutional constraints and uncertain system dynamics. However, solutions to help managers overcome these barriers are less common. How can we better integrate ecosystem stewardship into natural resource management practices? I draw on examples from the literature and two broadly applicable case studies from Alaska to suggest some generalizable principles that can help managers redirect how people use and view ecosystems. These include (1) accounting for both people and ecosystems in management...

From Complex Regions to Complex Worlds
Provedor de dados: 7
Autores: Holling, C. S.; University of Florida; holling@zoo.ufl.edu.
Panarchy focuses on ecological and social systems that change abruptly. Panarchy is the process by which they grow, adapt, transform, and, in the end, collapse. These stages occur at different scales. The back loop of such changes is a critical time and presents critical opportunities for experiment and learning. It is when uncertainties arise and when resilience is tested and established. We now see changes on a global scale that suggest that we are in such a back loop. This article assesses the possibility of using the ideas that are central to panarchy, developed on a regional scale, to help explain the changes that are being brought about on a global scale by the Internet and by climate, economic, and geopolitical changes.

Faced with numerous seemingly intractable social and environmental challenges, many scholars and practitioners are increasingly interested in understanding how to actively engage and transform the existing systems holding such problems in place.  Although a variety of analytical models have emerged in recent years, most emphasize either the social or ecological elements of such transformations rather than their coupled nature. To address this, first we have presented a definition of the core elements of a social-ecological system (SES) that could potentially be altered in a transformation. Second, we drew on insights about transformation from three branches of literature focused on radical change, i.e., social movements, socio-technical transitions, and...

Resilience is emerging as a promising vehicle for improving management of social-ecological systems that can potentially lead to more sustainable arrangements between environmental and social spheres. Central to an understanding of how to support resilience is the need to understand social change and its links with adaptation and transformation. Our aim is to contribute to insights about and understanding of underlying social dynamics at play in social-ecological systems. We argue that longstanding indigenous practices provide opportunities for investigating processes of adaptation and transformation. We use in-depth analysis of adaptation and transformation through engagement in participatory action research, focusing on the role of cultural and social...

I examined the multiple visions of the future of the city that can emerge when city actors and organizations reconfigure themselves to address sustainability. In various cities worldwide, novel ideas, initiatives, and networks are emerging in governance to address social and ecological conditions in urban areas. However, cities can be contested spaces, bringing a plurality of actors, network configurations, preferences, and knowledge that shape the politics over desirable pathways for future development. I used the knowledge-action systems analysis (KASA) approach to examine the frames and knowledge systems influencing how different actors involved in the land governance network of the city of San Juan constructed visions for the future of the city....

Plans to solve complex environmental problems should always consider the role of surprise. Nevertheless, there is a tendency to emphasize known computable aspects of a problem while neglecting aspects that are unknown and failing to ask questions about them. The tendency to ignore the noncomputable can be countered by considering a wide range of perspectives, encouraging transparency with regard to conflicting viewpoints, stimulating a diversity of models, and managing for the emergence of new syntheses that reorganize fragmentary knowledge.

Emergent transformation games: exploring social innovation agency and activation through the case of the Belgian electricity blackout threat
Provedor de dados: 7
The persistence of current societal problems has given rise to a quest for transformative social innovations. As social innovation actors seek to become change makers, it has been suggested that they need to play into impactful macrodevelopments or &amp;#8220;game-changers&amp;#8221;. Here, we aim to deepen the understanding of the social innovation agency in these transformation games. We analyze assumptions about the game metaphor, invoking insights from actor-network theory. The very emergence of transformation games is identified as a crucial but easily overlooked issue. As explored through the recent electricity blackout threat in Belgium, some current transformation games are populated with largely passive players. This illustrative case demonstrates...

Climate change and its interactions with complex socioeconomic dynamics dictate the need for decision makers to move from incremental adaptation toward transformation as societies try to cope with unprecedented and uncertain change. Developing pathways toward transformation is especially difficult in regions with multiple contested resource uses and rights, with diverse decision makers and rules, and where high uncertainty is generated by differences in stakeholders&amp;#8217; values, understanding of climate change, and ways of adapting. Such a region is the Murray-Darling Basin, Australia, from which we provide insights for developing a process to address these constraints.

Autores: Yongzhong,Lu; Zhang,Xuecheng.
In cyanobacteria, few details are known of the mechanisms through which the expression of the light-harvesting pigment c-phycocyanin is regulated. In the present study, a 419 bp upstream sequence of the phycocyanin b subunit (cpcB) gene from Arthrospira platensis FACHB341 was fused with green fluorescent protein (gfp) gene, and a heterologous reporting system was built up to investigate the influence of light intensity on the expression of gfp gene, and the regulation function of different region of the upstream sequence of cpcB gene. Results showed that the upstream sequence of cpcB gene could drive the expression of gfp gene in Synechococcus sp. strain PCC7942, and the expression was influenced by light intensity, the lower the light intensity, the...

This paper describes an efficient bacterial transformation system that was established for the preparation of competent cells, plasmid preparation, and for the storage in bacterial stocks in our laboratory. Using this method, a number of different plasmids have been amplified for further experiments. Competent cells for bacterial transformation were prepared by the calcium chloride method with an optimum concentration of 75 mM. Three different strains of Escherichia coli that were tested are DH5&amp;#945;, TG1 and XL1 blue, and the most efficient strain being XL1 blue. The optimal optical density (OD600) range for competent cell preparation varied for each of the strains investigated, and for XL1 blue it was 0.15-0.45; for TG1 it was 0.2-0.5; and for...

In the present study, a novel plant transformation system for Doritaenopsis and Phalaenopsis has been developed. The pollen-mediated activation tagging system was established by artificial pollination. The pollens, co-cultured with Agrobacterium tumefaciens strain EHA105 harbouring an activation tagging vector (pTAG-8), were used for pollination. In order to optimize the transformation efficiency, several factors (concentration of A. tumefaciens, concentration of acetosyringone during co-cultivation and the duration of co-cultivation) known to influence Agrobacterium-mediated DNA transfer were examined. A concentration of 0.5-1 x 10(8) CFU/ml for A. tumefaciens, 0.1 mM acetosyringone, and 6 hrs of co-culture period were found to be the optimal condition...

In molecular biology, transformation using E. coli as a host plays a key role in synthesizing gene libraries. The present study demonstrated a new ethanol-based method for transformation of plasmid DNA to E. coli. Ethanol at 10% concentration (v/v) showed best results. Further, as compared with traditional CaCl2 method, the transformation rate, using protocol outlined in this study, was very high, suggesting amenable for further applications.

Analysis and sequencing of h6hmRNA, last enzyme in the tropane alkaloids pathway from anthers and hairy root cultures of Brugmansia candida (Solanaceae)
Provedor de dados: 69
Autores: Cardillo,Alejandra B.; Giulietti,Ana M.; Marconi,Patricia L.
Brugmansia candida (Solanaceae) is a native tree distributed across South-American and produces the pharmacologically- important group of tropane alkaloids including scopolamine. This biocompound is synthesised from hyoscyamine by action of Hyoscyamine 6-&amp;beta; hydroxylase (H6H, EC 1.14.11.11) at the end of the tropane alkaloid pathway. Here are reported the tissue and organ-specific expression of h6hmRNA by RT-PCR analyses and the isolation, cloning and sequencing of the cDNA obtained from B. candida anthers and hairy root transformed cultures. Bioinformatic analysis of the nucleotide sequence revealed an uninterrupted ORF of 1038 bp and the predicted aminoacid sequence could be 344 aminoacid long. A database search showed that this sequence has high...

The genetically transformed roots of red beet have been shown, for the first time, to produce very high levels of peroxidase (POD; EC 1.11.1.7) accounting for 1.21 x 10(6) Units L-1. Of the ten clones established using different strains of Agrobacterium rhizogenes, one was that from the strain LMG-150, three each from A 2/83, A 20/83 and A4. All the clones showed true integration of T-DNA when tested by PCR and Southern hybridization methods. Each clone differed significantly from the others in growth, hormone dependency and POD production where LMG-150 produced highest biomass (140 g FW L-1) as well as POD (ranging from 8000-9000 U g-1 FW and 1.18 x 10(6) U L-1 with a specific activity of 600 U mg-1 protein) on hormone-free medium, both in shake-flask as...

Agrobacterium-mediated transformation of sorghum: factors that affect transformation efficiency
Provedor de dados: 74
Autores: Carvalho,Carlos Henrique S.; Zehr,Usha B.; Gunaratna,Nilupa; Anderson,Joseph; Kononowicz,Halina H.; Hodges,Thomas K.; Axtell,John D.
The results presented in this work support the hypothesis that Agrobacterium-mediated transformation of sorghum is feasible, analogous to what has been demonstrated for other cereals such as rice, maize, barley and wheat. The four factors that we found most influenced transformation were: the sensitivity of immature sorghum embryos to Agrobacterium infection, the growth conditions of the donor plant, type of explant and co-cultivation medium. A major problem during the development of our protocol was a necrotic response which developed in explants after co-cultivation. Immature sorghum embryos proved to be very sensitive to Agrobacterium infection and we found that the level of embryo death after co-cultivation was the limiting step in improving...

New biotechnological tools to accelerate scab-resistance trait transfer to apple
Provedor de dados: 74
Autores: Cusin,Roberta; Revers,Luís Fernando; Maraschin,Felipe dos Santos.
Abstract Apple is a fruit crop cultivated worldwide. Apple orchards are exposed to a diverse set of environmental and biological factors that affect the productivity and sustainability of the culture. Many of the efforts and costs for apple production rely on reducing the incidence of fungal diseases, and one of the main diseases is apple scab caused by the fungus Venturia inaequalis. The economic impact of scab on apple productivity has guided many breeding programs to search for cultivars resistant to apple scab. Introgression from wild relatives has been successful to some extent, and genetic engineering for resistant cultivars has even been employed. This review presents the techniques used to the present time to obtain pathogen-resistant apple...

Synthetic and minimalist vectors for Agrobacterium tumefaciens-mediated transformation of fungi
Provedor de dados: 74
Autores: Nora,Luísa Czamanski; Gonçales,Relber Aguiar; Martins-Santana,Leonardo; Ferreira,Beatriz Henriques; Rodrigues,Fernando; Silva-Rocha,Rafael.
Abstract We present a collection of minimalist binary vectors for transformation through ATMT applicable to several fungi species. pLUO plasmid binary vectors consist of a reporter module containing fluorescent proteins, mCherry or eGFP, flanked by a multiple cloning site and a transcription terminator site. They also present a synthetic gene allowing resistance to Hygromicin B flanked by alternate promoters, one for yeast and another for filamentous fungi. Left and right borders were added for Agrobacterium tumefaciens recognition, and a minimal broad-host range RK2 replication origin. Transformation was validated in the pathogenic fungus Paracoccidioides lutzii. Hence, we developed an efficient and reliable molecular tool for fungal transformation:...

Autores: Penven, Anais.
Beyond the technical and technological advances in the conversion of marine by-products into useful products, the territorial, economic, social, political and environmental parameters, which govern all forms of approaches for fish by-products upgrading, must be taken in account. This is essential to understand why and how bioconversion technologies are applicable. The fishery sector is facing several issues such as fish stocks weakening, recourse to imports, aquaculture rising or consumers behaviors which complicate the approach of fish by-products upgrading as it is linked to the raw material processing. Thanks to some projects addressed this thematic in recent years, several quantitative and qualitative data about by-products deposits are available....

Herinneringen aan een reis naar Sint-Helena

Autores: Hartog, J.C. den.
Volgens gangbare inzichten zijn vrijwel alle oceanische eilanden uit zee opgerezen, wat impliceert dat ze oorspronkelijk kaal en zonder enig leven waren. Biologen zijn daarom bijzonder geïnteresseerd in het karakter en de herkomst van de huidige flora en fauna van die eilanden en in de kolonisatieprocessen. In het algemeen kan men stellen dat de kans op kolonisatie kleiner is naarmate een eiland verder van het vasteland (of van een ander eiland) verwijderd ligt. In feite is de zaak natuurlijk wel iets gecompliceerder, en spelen allerlei factoren een rol. Voor landorganismen zijn dit onder meer de klimatologische en meteorologische omstandigheden in het te overbruggen gebied, en de vestigingsmogelijkheden in de nieuwe omgeving. Kolonisatie door mariene...

Autores: Queiroz,Paulo Roberto; Valadares-Inglis,Maria Cléria; Inglis,Peter Ward.
The objective of this work was to evaluate the survival of two Trichoderma harzianum co-transformants, TE 10 and TE 41, carrying genes for green fluorescent protein (egfp) and for resistance to benomyl, during four weeks in a contained soil microcosm. Selective culture media were used to detect viable fungal material, whose identity was confirmed by the observation of the fluorescent phenotype by direct epifluorence microscopy. PCR using two nested primer pairs specific to the egfp gene was also used to detect the transformed fungi. Although it was not possible to reliably detect the egfp gene directly from soil extracts, an enrichment step involving selective culture of soil samples in liquid medium prior to DNA extraction enabled the consistent detection...

Institutional Change of the Agricultural Administration and Rural Associations in East Germany before and after Unification
Provedor de dados: 31
Autores: Wolz,   Axel.
With the collapse of the socialist regime in East Germany in late 1989 and the rising political call for unification in early 1990, a radical and abrupt change of the institutional structure became necessary. Among others, the (agricultural) administration had to be totally restructured. This referred not only to substance, functions and tasks which had to be adjusted, similar to most other transition economies, to the market-economic and pluralistic democratic system, but also the whole administrative set-up had to be re-established in line with the West German system (territorial re-organisation). Hence, a new administrative system had to be built up in the East, while simultaneously the socialist one had to be dismantled. This transformation process...

Autores: Cox,   Nicholas J.
Ronald Aylmer Fisher suggested transforming correlations by using the inverse hyperbolic tangent, or atanh function, a device often called Fisher’s z transformation. This article reviews that function and its inverse, the hyperbolic tangent, or tanh function, with discussions of their definitions and behavior, their use in statistical inference with correlations, and how to apply them in Stata. Examples show the use of Stata and Mata in calculator style. New commands corrci and corrcii are also presented for correlation confidence intervals. The results of using bootstrapping to produce confidence intervals for correlations are also compared. Various historical comments are sprinkled throughout.

The following article analyses the structural changes of the Polish agriculture, which have been influenced by the transformation processes. These processes have been caused and influenced by phenomenas of a various scope and impact, but from the point of view of functioning of agricultural farming a few major factors may be outlined. Amongst the mentioned factors one can find: price decontrol and liberalisation, which have influenced the processes of price and agricultural products realisation, international trade realisation, which have ‘forced’ the increase of business competitiveness in the rural areas, liquidation of state owned and monopolized farming institutions, the lack of which has given those areas the push towards individualized...

Persistence of Dromiciops gliroides in landscapes dominated by Pinus radiata plantations
Provedor de dados: 97
Autores: Uribe,Sandra V.; Chiappe,Romina G.; Estades,Cristián F.
Abstract  Background  Monitos del monte (Dromiciops gliroides) are old-growth forest specialists and, thus, believed to be very sensitive to habitat transformation, although some recent studies show some level of plasticity of their habitat selection patterns.  Findings  In this note we report on records of D. gliroides living in a very modified environment, composed mostly by industrial pine plantations and small fragments of Nothofagus spp. forests and we report the extension of the northernmost limit of its currently known distribution.  Conclusions  Although highly reliant on native vegetation, Dromiciops gliroides has been able to persist in industrial forest landscapes dominated by pine plantations.

Abstract  Grape pomace from Vitis labrusca is an important sub-product of the “American table wine” industry. It is recalcitrant to degradation, and its accumulation is a serious problem with negative environmental impacts. We analyzed the ability of five white-rot fungi to transform this residue in-vitro. Mass loss and phenol removal in grape pomace treated with each fungus were compared after 30-day solid-state fermentation. Since Peniophora albobadia isolate LPSC 285 was the fungus that showed the highest degradative ability and the lowest free phenol levels in the residue transformed, we selected this fungus to monitor its effect on this residue after 30, 60, and 90 days of incubation. We analyzed mass loss of the residue caused by the fungus activity...

Restriction enzyme improves the efficiency of genetic transformations in Moniliophthora perniciosa, the causal agent of witches’ broom disease in Theobroma cacao
Provedor de dados: 52
Autores: Lopes,Francis Julio Fagundes; Queiroz,Marisa Vieira de; Lima,Juliana Oliveira; Silva,Viviane Aline Oliveira; Araújo,Elza Fernandes de.
The presence of restriction enzymes in the transformation mixture improved the efficiency of transformation in Moniliophthora perniciosa. The influence of the vector shape (linear or circular), the patterns of plasmid integration in genomic sites and the influence of the promoter used to express the gene marker were also analyzed. The addition of BamHI or NotI increased the number of transformants by 3-10-fold and 3-fold, respectively, over the control without added enzyme. The use of pre-linearized plasmid did not increase the transformation efficiency in comparison with the circular plasmid. However, the frequency of multi-copy transformants increased significantly. The transformation procedure here reported resulted in better production of protoplasts...

Transient gene expression of beta-glucuronidase in citrus thin epicotyl transversal sections using particle bombardment
Provedor de dados: 52
Autores: Bespalhok Filho,João C.; Kobayashi,Adilson K.; Pereira,Luiz F. P.; Galvão,Rafaelo M.; Vieira,Luiz G. E.
Studies were carried out to optimize the conditions for transient gene expression through particle bombardment on Carrizo citrange (Citrus sinensis x Poncirus trifoliata) thin epicotyl sections. The best conditions for transient GUS expression were: M-25 tungsten particles, 1550 psi helium pressure, 9 cm distance between specimen and DNA/particle holder and culture of explants in a high osmolarity medium (0.2 M mannitol + 0.2 M sorbitol) 4 h prior and 20 h after bombardment. Under these conditions, an average of 102 blue spots per bombardment (20 explants/plate) were achieved. This protocol is currently being used for transformation of Carrizo citrange and sweet orange (Citrus sinensis).

Yeast multi-copy vectors carrying the formaldehyde-resistance marker gene SFA have proved to be a valuable tool for research on industrially used strains of Saccharomyces cerevisiae. The genetics of these strains is often poorly understood, and for various reasons it is not possible to simply subject these strains to protocols of genetic engineering that have been established for laboratory strains of S. cerevisiae. We tested our vectors and protocols using 10 randomly picked baker's and wine yeasts all of which could be transformed by a simple protocol with vectors conferring hyperresistance to formaldehyde. The application of formaldehyde as a selecting agent also offers the advantage of its biodegradation to CO2 during fermentation, i.e., the selecting...

Abstract Streptococcus pneumoniae is one of the most frequent opportunistic pathogens worldwide. DNA processing protein A (DprA) is an important factor involved in bacterial uptake and DNA integration into bacterial genome, but its role in S. pneumoniae virulence remains unclear. The aim of this study was to characterize the effects of the pneumococcal dprA gene on the pathogenesis of S. pneumoniae. To construct a dprA-deficient pneumococcal strain, the dprA gene of the S. pneumoniae strain D39 was inactivated. The virulence of this dprA-deficient strain, designated ΔD39, was compared with that of the wild-type strain by evaluating their respective capabilities to adhere to human pulmonary epithelial cells (PEC-A549) and by analyzing their choline-binding...

Eleven salt tolerant bacteria isolated from different sources (soil, plants) and their transformed strains were used to study their influence on Triticum aestivum var. Inqlab-91 growth under salt (100 mM NaCl) stress. Salt stress caused reduction in germination (19.4%), seedling growth (46%) and fresh weight (39%) in non-inoculated plants. In general, both wild and transformed strains stimulated germination, seedling growth and fresh weight in salt free and salt stressed conditions. At 100 mM NaCl, Staphylococcus xylosus ST-1 caused 25% increments in seedling length over respective control. Soluble protein content significantly enhanced (49%) under salt stress as compared to salt free control. At 100 mM NaCl parental strain PT-5 resulted about 32%...

Autores: Rattanachaikunsopon,Pongsak; Phumkhachorn,Parichat.
A simple, inexpensive and reproducible transformation method was developed for Gram-positive bacteria. It was based on agitation of bacterial protoplasts with glass beads in the presence of DNA and polyethylene glycol. By using this method, introduction of pGK12 into protoplasts of several strains of Gram-positive bacteria was achieved.
