(CSIRO Publishing, 2013-09-05)The short-term (2 h) effects of salt stress (50 and 150 mM NaCl) on early events of soybean– Bradyrhizobium japonicum (rhizobia) interaction were analysed, determining the following parameters in root hair with or without ... -
Are Sunflower chlorotic mottle virus infection symptoms modulated by early increases in leaf sugar concentration?
(Elsevier, 2010-09-15)Symptom development in a susceptible sunflower line inoculated with Sunflower chlorotic mottle virus (SuCMoV) was followed in the second pair of leaves at different post-inoculation times: before symptom expression (BS), ... -
Soybean pod and grain isoflavones accumulation during the filling period in field conditions
(Ediciones INTA, 2021-12)The objective of this work was to determine the isoflavones accumulation in soybean pods and grains during the filling period in field conditions. Pods of the same phenological stage (marked in R5, i.e. beginning of grain ... -
Differential response of Trichloris ecotypes from different habitats to drought and salt stress
(Springer, 2020-08-05)Native plant genetic resources have evolved from long processes of natural selection and adaptation to specific environments, and have developed tolerance to various stresses prevailing in their natural habitats via adaptive ... -
Nuevos cultivares de gramíneas forrajeras subtropicales para ambientes restrictivos
(Ministerio de Ciencia y Tecnología, Argentina, 2021-10)En los últimos años, se ha generado un nuevo escenario productivo en Argentina a consecuencia del desplazamiento de la ganadería hacia zonas no agrícolas con restricciones edafo-climáticas adversas, entre ellas, suelos de ... -
Protección contra el estrés ambiental en cultivos: cultivares tolerantes y microorganismos benéficos
(Ministerio de Ciencia y Tecnología, Argentina, 2021-10)Anualmente la sequia en los campos de Córdoba reduce los rendimientos de los alimentos entre 30% 50% de la cosecha potencial, según el cultivo. -
Respuestas fisiológicas de materiales de soja en simbiosis con micorrizas bajo estrés por sequía
(REDBIO, 2021-06)Encontrar estrategias para mitigar las pérdidas por sequía en plantas, resulta un desafío para la agricultura Una posibilidad es desarrollar tecnologías para aprovechar los beneficios de las simbiosis con los hongos ... -
The chlorotic symptom induced by Sunflower chlorotic mottle virus is associated with changes in redox-related gene expression and metabolites
(Elsevier, 2012-08-18)Systemic infections are commonly associated with changes in host metabolism and gene expression. Sunflower chlorotic mottle virus (SuCMoV) causes systemic infection with sugar increase, photoinhibition and increase in ... -
