Insights from a Multi-Omics Integration (MOI) Study in Oil Palm (Elaeis gineensis Jacq.) Response to Abiotic Stresses: Part One?Salinity. Repositório Alice
BITTENCOURT, C. B.; SILVA, T. L. C. da; RODRIGUES NETO, J. C.; VIEIRA, L. R.; LEAO, A. P.; RIBEIRO, J. A. de A.; ABDELNUR, P. V.; SOUSA, C. A. F. de; SOUZA JUNIOR, M. T..
Oil palm (Elaeis guineensis Jacq.) is the number one source of consumed vegetable oil nowadays. It is cultivated in areas of tropical rainforest, where it meets its natural condition of high rainfall throughout the year. The palm oil industry faces criticism due to a series of practices that was considered not environmentally sustainable, and it finds itself under pressure to adopt new and innovative procedures to reverse this negative public perception. Cultivating this oilseed crop outside the rainforest zone is only possible using artificial irrigation. Close to 30% of the world?s irrigated agricultural lands also face problems due to salinity stress. Consequently, the research community must consider drought and salinity together when studying to...

Maize transformation: from plant material to the release of genetically modified and edited varieties. Repositório Alice
YASSITEPE, J. E. de C. T.; SILVA, V. C. H. da; HERNANDES-LOPES, J.; DANTE, R. A.; GERHARDT, I. R.; FERNANDES, F. R.; SILVA, P. A. da; VIEIRA, L. R.; BONATTI, V.; ARRUDA, P..
Over the past decades, advances in plant biotechnology have allowed the development of genetically modified maize varieties that have significantly impacted agricultural management and improved the grain yield worldwide. To date, genetically modified varieties represent 30% of the world´s maize cultivated area and incorporate traits such as herbicide, insect and disease resistance, abiotic stress tolerance, high yield, and improved nutritional quality. Maize transformation, which is a prerequisite for genetically modified maize development, is no longer a major bottleneck. Protocols using morphogenic regulators have evolved significantly towards increasing transformation frequency and genotype independence. Emerging technologies using either stable or...

Metabolic effect of drought stress on the leaves of young oil palm (Elaeis guineensis) plants using UHPLC-MS and multivariate analysis. Repositório Alice
RODRIGUES NETO, J. C.; VIEIRA, L. R.; RIBEIRO, J. A. de A.; SOUSA, C. A. F. de; SOUZA JUNIOR, M. T.; ABDELNUR, P. V..
Abstract: The expansion of the oil palm in marginal areas can face challenges, such as water deficit, leading to an impact on palm oil production. A better understanding of the biological consequences of abiotic stresses on this crop can result from joint metabolic profiling and multivariate analysis. Metabolic profiling of leaves was performed from control and stressed plants (7 and 14 days of stress). Samples were extracted and analyzed on a UHPLC-ESI-Q-TOF-HRMS system. Acquired data were processed using XCMS Online and MetaboAnalyst for multivariate and pathway activity analysis. Metabolism was affected by drought stress through clear segregation between control and stressed groups. More importantly, metabolism changed through time, gradually from 7 to...

Morphophysiological responses of Setaria viridis to cold stress. Repositório Alice
CARVALHO, C. G. I.; SANTOS, M. de L.; VIEIRA, L. R.; LOPES, A. M.; CARMONA, P. A. O.; SOUSA, C. A. F. de; SOUZA JUNIOR, M. T..
ABSTRACT - The objective of this work was to determine the suitability of Setaria viridis as a model plant in studies to validate candidate genes for cold tolerance by evaluating the response of two of its accessions to different durations of abrupt or gradual cold stress in the vegetative and reproductive stages. Plants of accessions A10.1 and Ast-1, cultivated at 25°C, were subjected to the following cold stress treatments: gradual reduction in temperature from 25 to 0°C, 5°C at a time, every 24 hours in a same chamber; or abrupt reduction in temperature, by transferring plants from a chamber at 25°C to another at 0°C. Plants were kept at 0°C for 3, 5, or 10 days, after which temperature was increased back again to 25°C; a control group remained at 25ºC....

Regulatory framework of genome editing in Brazil and worldwide. Repositório Alice
VIEIRA, L. R.; FREITAS, N. C.; JUSTEN, F.; MIRANDA, V. de J.; GARCIA, B. de O.; NEPOMUCENO, A. L.; FUGANTI-PAGLIARINI, R.; FELIPE, M. S. S.; MOLINARI, H. B. C.; VELINI, E. D.; PINTO, E. R. de C.; DAGLI, M. L. Z.; ANDRADE, G.; FERNANDES, P. M. B.; MERTZ-HENNING, L. M.; KOBAYASHI, A. K..
The regulation of the use of products obtained through genome-editing techniques has been the subject of great debate worldwide. Currently, the discussions are mainly focused on whether products obtained by different strategies of site-directed nucleases (SDN) should or not be classified as Genetically Modified Organisms (GMOs). In the SDN-1 application, the natural DNA cell repair pathway (Non-Homologous End-Joining - NHEJ) is explored to introduce simple random mutations (substitutions, insertions, and deletions) by systems such as CRISPR-Cas, TALENs, or Zinc Fingers Nucleases, which cause silencing of the gene product after breaking DNA (by Double-Strand Break - DSB). In the SDN-2 approach, a template DNA is also used to introduce a change in the...
