Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ... -
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 ... -
Respuesta a temprana edad de nuevos genotipos de salix spp ante estrés abiótico en un “bajo dulce” de Chascomus, provincia de Buenos Aires
(2014-03-18)En sitios de la Pampa Deprimida de la provincia de Buenos Aires la salinidad y/o alcalinidad de los suelos y los períodos de alternancia de exceso hídrico, seguidos de déficit pronunciado de agua, generan situaciones de ... -
Respuesta anatómica y fisiológica de especies de Nothofagus de Patagonia austral ante la variación de temperatura, humedad, CO2 y nutrientes
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2021-04-05)Tomando los bosques nativos de Nothofagus de la Patagonia austral como objeto de estudio, se han desarrollado diversas investigaciones en los distintos capítulos de la tesis, para evaluar la respuesta de estas especies ... -
Respuestas fisiológicas a estrés salino e hídrico en Vitis vinifera l. (cv. Cabernet sauvignon) sobre dos portainjertos
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2017)En zonas áridas bajo riego, los viñedos enfrentan condiciones de déficit hídrico y salinidad. Como frecuentemente estos factores de estrés ocurren simultáneamente, es difícil evaluar la gravedad relativa de cada uno de ... -
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 ... -
Salinity induced anatomical and morphological changes in Chloris gayana Kunth roots
(Universidad Nacional de Cuyo, 2011)Chloris gayana Kunth is a grass species valuable as forage which was introduced into Argentina to be used as pasture in saline soils of subtropical and warm-temperate zones, given its good adaptability to drought, salinity ... -
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. ... -
Soybean seed growth dynamics exposed to heat and water stress during the filling period under field conditions
(Wiley, 2021-05-27)Soybean production can be affected by heat (HS) and water stress (WS). However, studies on effects of stresses combination under field conditions are still scarce. The objective of this study was to evaluate the impact of ... -
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(2014-02)The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ... -
Synthetic Communities of Bacterial Endophytes to Improve the Quality and Yield of Legume Crops
(IntechOpen, 2022-03-31)Plant-associated microbiomes confer fitness advantages to the plant host by growth promotion through different mechanisms including nutrient uptake, phytohormones production, resistance to pathogens, and stress tolerance. ... -
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 ... -
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 ... -
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, ... -
