The Activity of the Chloroplastic Ndh Complex Is Regulated by Phosphorylation of the NDH-F Subunit
(American Society of Plant Biologists, 2003-05-01)Hydrogen peroxide (H2O2) induces increases, to different degrees, in transcripts, protein levels, and activity of the Ndh complex (EC 1.6.5.3). In the present work, we have compared the effects of relatively excess light, ... -
The Arabidopsis chromatin regulator MOM1 is a negative component of the defense priming induced by AZA, BABA and PIP
(Frontiers Media, 2023-05-09)In plants, the establishment of broad and long-lasting immunity is based on programs that control systemic resistance and immunological memory or “priming”. Despite not showing activated defenses, a primed plant induces a ... -
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 ... -
The role of inoculum identity in drought stress mitigation by arbuscular mycorrhizal fungi in soybean
(2015-01)It is well known that arbuscular mycorrhizal fungi (AMF) effects on plant growth largely depend on fungus identity. The objective of this study was to test whether three individual AMF isolates and their mixture mitigate ... -
Tiller population dynamics and self-thinning law reveal stability mechanisms in mixed grass swards under variable grazing management
(Cambridge University Press, 2025-02-26)Grazing management is an important component affecting pasture stability, but the underlying demographic mechanisms remain poorly understood in mixed-species systems. This three-year study investigated how grazing height ... -
Tolerancia a la salinidad: respuestas morfo-fisiológicas en diferentes etapas del desarrollo en dos cultivares de alfalfa = Salinity tolerance: morpho-physiological responses at different developmental stages in two alfalfa cultivars
(Universidad Católica de Córdoba, 2024-04-05)En el marco del cambio climático, la producción en suelos salinos surge como un desafío global de gran importancia, especialmente en regiones áridas de Argentina. Este estudio se enfoca en la alfalfa (Medicago sativa), una ... -
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 ... -
Tratamientos profesionales de semilla en siembra temprana: impacto en la implantación y rendimiento en grano de soja
(Asociación de Laboratorios Agropecuarios Privados ( ALAP), 2020-11)El potencial productivo de un cultivo comienza con una implantación exitosa. Los tratamientos de semilla son una práctica cada vez más difundida especialmente ante situaciones que reducen la velocidad de germinación y ... -
Turnip Mosaic Virus impairs thermomorphogenetic responses in Arabidopsis plants amid genetic and hormonal disruption
(Sociedad Argentina de Fisiología Vegetal, 2025-08)BACKGROUND: • Plants rely on thermomorphogenesis (TMG) to adapt their growth and development in response to moderate temperature increases, a process mainly regulated by the PIF4 (Phytochrome Interacting Factor 4) transcription ... -
Unraveling resilience amidst degradation: Recurring loss of freshwater marshes in the Paraná River Delta, Argentina
(Elsevier, 2024-11)Wetland ecosystems have experienced several ecological and hydrological impacts in recent decades determined by human activities and natural disturbances. The Lower Delta of the Paraná River, one of the most important ... -
Unraveling the forage productivity puzzle: comparing fast and slow-growing grasses
(PLoS One, 2024-07-30)Functional traits are powerful tools for distinguishing between plants with different resource acquisition strategies. Fast-growing plants normally dominate resource-rich habitats and present trait values associated with ... -
El uso de nanofertilizantes impacta en el porcentaje de micorrizacion y rendimiento de soja
(Asociación Argentina Ciencia del Suelo (AACS), 2022-11-15)En la región de Cerrado, Rio Verde Goiás- Brasil, los productores rurales buscan aumentar la productividad del cultivo de soja de forma eficiente. En este sentido, el empleo de nanofertilizantes causa un gran impacto, ya ... -
Utilización del Estrés oxidativo y la defensa antioxidante para la caracterización e identificación temprana de genotipos de Cenchrus Ciliaris L. tolerantes al estrés abiótico.
(Edición de Autor, 2018-11-23)La sequía y el estrés por calor son dos tipos de estrés abiótico importantes que afectan el crecimiento de los cultivos y la agricultura en todo el mundo. Muchos estudios se han enfocado en analizar la respuesta de los ... -
