Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ... -
Estrés y muerte celular programada en leguminosas: efectos de la expresión de supresores de muerte celular
(Facultad de Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba, 2012)En leguminosas, condiciones de estrés aceleran el proceso de senescencia e inducen muerte celular, comprometiendo la asimilación del carbono, la fijación biológica del nitrógeno y en consecuencia el crecimiento y la ... -
High Sugar Concentration Inhibits TOR Signaling Pathway in Arabidopsis thaliana
(Springer, 2023-01-20)Sugars are not only energy sources, but also central molecular signals that regulate growth, development, and response to environmental stresses. It is well recognized that sugars activate TOR kinase, the key integrator ... -
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 ... -
Salt tolerance variability among stress‐selected Panicum coloratum cv. Klein plants
(Wiley; British Grassland Society; European Grassland Federation, 2016-11)This work assessed intracultivar variability for salt tolerance within Panicum coloratum cv. Klein, explored some physiological parameters potentially associated with it and evaluated the contribution of cell division and ... -
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 ...
