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 ... -
Root hydraulic conductivity and adjustments in stomatal conductance: hydraulic strategy in response to salt stress in a halotolerant species
(Oxford University Press, 2015-11)Recent advances at the molecular level are introducing a new scenario that needs to be integrated into the analysis of plant hydraulic properties. Although it is not yet clear to what extent this scenario alters the current ... -
Saline and osmotic stress differentially affects apoplastic and intracellular reactive oxygen species production, curling and death of root hair during Glycine max L.–Bradyrhizobium japonicum interaction
(Elsevier, 2011-12-08)In the present study, the production of apoplastic and intracellular reactive oxygen species (ROS) and deformations of young soybean root hairs inoculated with Bradyrhizobium japonicum strain USDA138 were analyzed under ... -
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 ... -
Sistemas de fenotipado para la evaluación de las respuestas al estrés salino en Lotus
(Facultad de Agronomía, Universidad de la República e Instituto Nacional de Investigación Agropecuaria, Uruguay, 2013-06-01)La tolerancia al estrés salino es un carácter complejo determinado por la sumatoria de los efectos de numerosos genes, cuya identificación es necesaria para la definición de estrategias de mejoramiento. En este sentido, ... -
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 ... -
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 ... -
Variabilidad Fenotípica para tolerancia a salinidad de un panel de asociación de sorgo
(Red Argentina de Salinidad, 2023-09-19)La Argentina es, según FAO UNESCO, el tercer país con mayor superficie de suelos afectados por halomorfismo en el mundo, después de Rusia y Australia. El sorgo constituye un alimento básico de las regiones semiáridas de ... -
Why are Chloris gayana leaves shorter in salt-affected plants? Analyses in the elongation zone
(Society for Experimental Biology, 2006-11)Reduced hydraulic conductance calculated from growth data was suggested to be the main reason for reduced leaf expansion in salt-stressed Chloris gayana (Rhodes grass). In this work, xylem vessel cross-sections and wall ...
