An overall evaluation of the resistance (R) and pathogenesis-related (PR) superfamilies in soybean, as compared with Medicago and Arabidopsis. Repositório Alice
WANDERLEY-NOGUEIRA, A. C.; BELARMINO, L. C.; SOARES-CAVALCANTI, N. da M.; BEZERRA-NETO, J. P.; KIDO, E. A.; PANDOLFI, V.; ABDELNOOR, R. V.; BINNECK, E.; CARAZZOLE, M. F.; BENKO-ISEPPON, A. M..
Plants have the ability to recognize and respond to a multitude of pathogens, resulting in a massive reprogramming of the plant to activate defense responses including Resistance (R) and Pathogenesis-Related (PR) genes. Abiotic stresses can also activate PR genes and enhance pathogen resistance, representing valuable genes for breeding purposes. The present work offers an overview of soybean R and PR genes present in the GENOSOJA (Brazilian Soybean Genome Consortium) platform, regarding their structure, abundance, evolution and role in the plantpathogen metabolic pathway, as compared with Medicago and Arabidopsis. Searches revealed 3,065 R candidates (756 in Soybean, 1,142 in Medicago and 1,167 in Arabidopsis), and PR candidates matching to 1,261 sequences...

Comparative analysis of differentially expressed sequence tags of sweet orange and mandarin infected with Xylella fastidiosa Genet. Mol. Biol.
Souza,Alessandra A. de; Takita,Marco A.; Coletta-Filho,Helvécio D.; Campos,Magnólia A.; Teixeira,Juliana E.C.; Targon,Maria Luísa P.N.; Carlos,Eduardo F.; Ravasi,Juliano F.; Fischer,Carlos N.; Machado,Marcos A..
The Citrus ESTs Sequencing Project (CitEST) conducted at Centro APTA Citros Sylvio Moreira/IAC has identified and catalogued ESTs representing a set of citrus genes expressed under relevant stress responses, including diseases such as citrus variegated chlorosis (CVC), caused by Xylella fastidiosa. All sweet orange (Citrus sinensis L. Osb.) varieties are susceptible to X. fastidiosa. On the other hand, mandarins (C. reticulata Blanco) are considered tolerant or resistant to the disease, although the bacterium can be sporadically detected within the trees, but no disease symptoms or economic losses are observed. To study their genetic responses to the presence of X. fastidiosa, we have compared EST libraries of leaf tissue of sweet orange Pêra IAC (highly...

Defense-related proteins involved in sugarcane responses to biotic stress Genet. Mol. Biol.
Souza,Thais P.; Dias,Renata O.; Silva-Filho,Marcio C..
Abstract Sugarcane is one of the most important agricultural crops in the world. However, pathogen infection and herbivore attack cause constant losses in yield. Plants respond to pathogen infection by inducing the expression of several protein types, such as glucanases, chitinases, thaumatins, peptidase inhibitors, defensins, catalases and glycoproteins. Proteins induced by pathogenesis are directly or indirectly involved in plant defense, leading to pathogen death or inducing other plant defense responses. Several of these proteins are induced in sugarcane by different pathogens or insects and have antifungal or insecticidal activity. In this review, defense-related proteins in sugarcane are described, with their putative mechanisms of action, pathogen...

BAZIOLI, J. M.; GUIMARÃES, P. de S.; STRAZZA, B. A.; SCHENK, J. C. M.; PADILHA, L.; GUERREIRO-FILHO, O.; MALUF, M. P..
O objetivo deste estudo é o desenvolvimento de marcadores do tipo SNPs associados com a resistência ao bicho-mineiro em café. A estratégia principal utilizou as análises genômicas de microarranjo, para caracterização de expressão diferencial de genes-candidatos em plantas resistentes infestadas com o bicho-mineiro. Inicialmente, análises in silico de 2137 destes genes identificaram aqueles potencialmente relacionados com a especificidade da resposta de defesa da planta. Uma vez selecionados, o perfil de expressão de 22 genes foi confirmado por qRT-PCR em experimentos utilizando plantas resistentes e suscetíveis, infectadas pelo bicho-mineiro. Para busca de polimorfismos do tipo SNPs, que poderão ser utilizados como marcadores para seleção-assistida,...

Differential expression of genes identified from Poncirus trifoliata tissue inoculated with CTV through EST analysis and in silico hybridization Genet. Mol. Biol.
Cristofani-Yaly,Mariângela; Berger,Irving J.; Targon,Maria Luisa P.N.; Takita,Marco A.; Dorta,Sílvia de O.; Freitas-Astúa,Juliana; Souza,Alessandra A. de; Boscariol-Camargo,Raquel L.; Reis,Marcelo S.; Machado,Marcos A..
Citrus is the most important fruit crop in Brazil and Citrus tristeza virus (CTV) is considered one of the most important pathogens of citrus. Most citrus species and varieties are susceptible to CTV infection. However, Poncirus trifoliata, a close relative of citrus, is resistant to the virus. In order to better understand the responses of citrus plants to the infection of CTV, we constructed expressed sequence tag (EST) libraries with tissues collected from Poncirus trifoliata plants, inoculated or not with Citrus tristeza virus at 90 days after inoculation, grafted on Rangpur lime rootstocks. We generated 17,867 sequence tags from Poncirus trifoliata inoculated (8,926 reads) and not (8,941 reads) with a severe CTV isolate. A total of 2,782 TCs...

Entangled effects of allelic and clonal (genotypic) richness in the resistance and resilience of experimental populations of the seagrass Zostera noltii to diatom invasion ArchiMer
Massa, Sonia I.; Paulino, Cristina M.; Serrao, Ester A.; Duarte, Carlos M.; Arnaud-haond, Sophie.
Background: The relationship between species diversity and components of ecosystem stability has been extensively studied, whilst the influence of the genetic component of biodiversity remains poorly understood. Here we manipulated both genotypic and allelic richness of the seagrass Zostera noltii, in order to explore their respective influences on the resistance of the experimental population to stress. Thus far intra-specific diversity was seldom taken into account in management plans, and restoration actions showed very low success. Information is therefore needed to understand the factors affecting resistance and resilience of populations. Results: Our results show a positive influence of both allelic and genotypic richness on the resistance of...

Genetic dissimilarity for resistance to Mononychellus tanajoa (bondar) (Acari, Tetranychidae) among domesticated and wild Manihot species Agronomy
Boaventura, Verônica de Jesus; Ringenberg, Rudiney; Ledo, Carlos Alberto da Silva.
The aim of this study was to evaluate the genetic dissimilarity among wild and domesticated species of Manihot for resistance to cassava green mite during the insect life cycle. Nine accessions of wild Manihot species, M. esculenta ssp. flabellifolia, M. esculenta ssp. peruviana, and M. carthaginensis ssp. glaziovii, and two clones of M. esculenta (Cigana Preta and Sacaí) were evaluated under laboratory conditions at 25 ± 1°C, 70 ± 10% RH, and a 12-h photophase. Daily observations during the mite life cycle stages (larva-adult) were recorded. The data were subjected to an analysis of variance, a Scott-Knott test (5%), and Singh criterion, cluster, and principal component analyses. The larval-adult period ranged from 5.53 to 7.01 days: the longest period...

Germination Ecology of Ivy-Leaved Morning-Glory: an Invasive Weed in Soybean Fields, Iran Planta Daninha
SIAHMARGUEE,A.; GORGANI,M.; GHADERI-FAR,F.; ASGARPOUR,R..
ABSTRACT: Ivy-leaved morning-glory (Ipomoea hederacea Jacq.) is an exotic species that is becoming an increasing problem in soybean fields of Golestan province, Iran. Because little information is available on the biology of this weed species in Iran, experiments were conducted to investigate the effects of different factors on seed germination and emergence of Ivy-leaved morning-glory. Maximum germination occurred at constant temperature of 20 oC (82%) and alternating temperature of 15/25 oC (94%). Germination was reduced with increasing salinity and drought stresses. Sodium chloride concentration and osmotic potential that inhibited 50% maximum germination were -1.64 and -1.03 MPa, respectively. Acidity was a limiting factor for the germination, due to...

New biotechnological tools to accelerate scab-resistance trait transfer to apple. Repositório Alice
CUSIN, R.; REVERS, L. F.; MARASCHIN, F. dos S..
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...
