Análisis genómico de girasol: desarrollo de colecciones de ESTs y de una plataforma bioinformática para estudios de expresión de genes candidato en respuestas a estreses abióticos
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2006)El girasol es uno de los principales cultivos oleaginosos del mundo por su volumen de producción y composición en ácidos grasos insaturados. En promedio, durante los últimos cinco años, la producción mundial se ha mantenido ... -
Aplicación de técnicas no convencionales para la obtención de variabilidad genética en Panicum maximum Jacq.
(Universidad Nacional de Luján, 2016)En los últimos años el incremento de la agricultura provocó un reordenamiento territorial de la ganadería hacia regiones extrapampeanas con ambientes más restrictivos. El “Gatton Panic” (Panicum maximum Jacq. cv. Gatton) ... -
Caracterización bioquímica de razas nativas de maíz de Argentina en ensayos de jardín común
(Instituto Nacional de Tecnología Agropecuaria (INTA), 2024-11)En Argentina existen alrededor de 60 razas nativas de maíz (Zea mays ssp. mays), con dos centros principales de diversidad en las regiones andina y chaqueña-mesopotámica. Estas razas nativas presentan una alta diversidad ... -
Maize drought protection by Azospirillum argentinense Az19 requires bacterial trehalose accumulation
(Springer, 2024-12-27)Azospirillum argentinense Az19 is an osmotolerant plant growth-promoting bacterium that protects maize plants from drought. In this work, we explored the role of trehalose in the superior performance of Az19 under stress. ... -
mRNA biogenesis-related helicase eIF4AIII from Arabidopsis thaliana is an important factor for abiotic stress adaptation
(2016)Similar to other plant species, Arabidopsis has a huge repertoire of predicted helicases, including the eIF4AIII factor, a putative component of the exon junction complex related to mRNA biogenesis. In this article, we ... -
Multiomics analyses reveal the roles of the ASR1 transcription factor in tomato fruits
(Oxford University Press, 2021-09)The transcription factor ASR1 (ABA, STRESS, RIPENING 1) plays multiple roles in plant responses to abiotic stresses as well as being involved in the regulation of central metabolism in several plant species. However, despite ... -
Plant growth-promoting bacterium Pseudomonas fluorescens FR1 secrets a novel type of extracellular polyhydroxybutyrate polymerase involved in abiotic stress response in plants
(Springer, 2018)Objectives Identification of novel microbial factors contributing to plant protection against abiotic stress. Results The genome of plant growth-promoting bacterium Pseudomonas fluorescens FR1 contains a short mobile ... -
Snakin/GASA proteins : involvement in hormone crosstalk and redox homeostasis
(Taylor & Francis, 2012)Snakin/GASA proteins are widely distributed among plant species. They are expressed in different plant organs with high tissue and temporal specificity, and their subcellular localization varies among the different members. ... -
Tomato Abscisic Acid Stress ripening (ASR) gene family revisited
(PLOS, 2014-10-13)Tomato ABSCISIC ACID RIPENING 1 (ASR1) was the first cloned plant ASR gene. ASR orthologs were then cloned from a large number of monocot, dicot and gymnosperm plants, where they are mostly involved in response to abiotic ... -
Transcript and metabolic adjustments triggered by drought in Ilex paraguariensis leaves
(Springer, 2019-08)Ilex paraguariensis (yerba mate) is cultivated in the subtropical region of South America, where the occurrence of drought episodes limit yield. To explore the mechanisms that allow I. paraguariensis to overcome dehydration, ...
