Wild halophytic species as forage sources: key aspects for plant breeding
(Wiley; British Grassland Society; European Grassland Federation, 2019-02-20)The use of wild halophytic species as forage resources in saline environments has gained increasing attention. Argentina ranks third in area of saline soils in the world, with a third of its territory showing various degrees ... -
A bacterial endophyte from apoplast fluids protects canola plants from different phytopathogens via antibiosis and induction of host resistance
(American Phytopathological Society, 2019-03)Endophytic bacteria colonize inner plant tissues and thrive at the apoplast, which is considered its main reservoir. Because this niche is the place where the main molecular events take place between beneficial and pathogenic ... -
Rol del sistema antioxidante de microsimbiontes de leguminosas y su relación con la tolerancia a estrés abiótico durante la simbiosis
(Facultad de Ciencias Exactas, Físico - Químicas y Naturales, Universidad Nacional de Río Cuarto, 2019-03)La sequía y la salinidad son los principales factores que afectan la fijación biológica de nitrógeno mediada por la simbiosis rizobio/leguminosa. Una de las respuestas globales a estas condiciones de estrés es el aumento ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
Interspecific hybridization improves the performance of Lotus spp. under saline stress
(Elsevier, 2019-06)Salinity is one of the most frequent limiting conditions in pasture production for grazing livestock. Legumes, such as Lotus spp. with high forage quality and capable of adapting to different environments, improves pasture ... -
Interactions between soybean, Bradyrhizobium japonicum and Soybean mosaic virus: the effects depend on the interaction sequence
(2019-06-25)The symbiotic interaction between soybean and nitrogen-fixing rhizobia can lead to plant growth promotion and induced systemic responses. Symbiotic interactions may increase tolerance/resistance to abiotic/biotic stress ... -
TOR and SnRK1 signaling pathways in plant response to abiotic stresses: Do they always act according to the "yin-yang" model?
(2019-08-13)Plants are sessile photo-autotrophic organisms continuously exposed to a variety of environmental stresses. Monitoring the sugar level and energy status is essential, since this knowledge allows the integration of external ... -
Composición de tocoferoles en soja bajo estrés térmico e hídrico durante el llenado de grano: variación según la posición en el canopeo
(Asociación de la Cadena de la Soja Argentina, 2019-09)La soja Glycine max (L.) Merr. representa aproximadamente 34% de la producción total de granos y 46% de la superficie agrícola sembrada en Argentina, convirtiéndose en el principal cultivo a nivel nacional (SIIA, 2018). ... -
Enmienda Orgánica de Suelo y su Efecto Sobre el Cultivo de Lechuga
(Secretaría de Ciencia, Técnica y Posgrado, Universidad Nacional de Cuyo, 2019-09-18)En el marco de las actividades de Investigación Acción Participativa (IAP) con productores del cinturón verde de Córdoba para la transición hacia sistemas productivos agroecológicos como proceso de innovación y mejora ... -
Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment
(Frontiers Media, 2019-11-04)Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae ... -
New insights into the molecular basis of induced resistance triggered by potassium phosphite in potato
(2019-11-12)This work aimed to provide data about the molecules involved in induced resistance mediated by potassium phosphite (KPhi) in potato. To achieve these, we performed microarray analysis to determine the changes in gene ... -
Bacillus subtilis ALBA01 alleviates onion pink root by antagonizing the pathogen Setophoma terrestris and allowing physiological status maintenance
(Springer, 2020)The soil-borne pathogen Setophoma terrestris is the causal agent of pink root of onion, one of the most challenging diseases in onion production. Conventional approaches for managing the disease like solarization, soil ... -
Evolutionary insights into FYVE and PHOX effector proteins from the moss Physcomitrella patens
(Springer, 2020-02)Phosphatidylinositol 3-phosphate (PtdIns3P) is a signaling phospholipid, which regulates several aspects of plant growth and development, as well as responses to biotic and abiotic stresses. The mechanistic insights ... -
Volcanism rather than climatic oscillations explains the shared phylogeographic patterns among ecologically distinct plant species in the southernmost areas of the South American Arid Diagonal
(Elsevier, 2020-05)Shared genetic patterns within a community of ecologically distinct species may reflect the role of past geoclimatic events imprinting species evolutionary history. Although Pleistocene glaciations are the most important ... -
