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 ... -
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 ... -
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 ... -
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 ... -
Volcanism rather than climatic oscillations explains the shared phylogeographic patterns among ecologically distinct plant species in the southernmost areas of the South American Arid Diagonal
(Elsevier, 2020-05)Shared genetic patterns within a community of ecologically distinct species may reflect the role of past geoclimatic events imprinting species evolutionary history. Although Pleistocene glaciations are the most important ... -
Water Deficit Modulates the Relationship between Temperature and Unsaturated Fatty Acid Profile in Soybean Seed Oil
(Crop Science Society of America, 2017-08-23)Soybean [Glycine max (L.) Merr.], a major source of vegetable oil worldwide, contains unsaturated fatty acids (UFA) beneficial for human health, leading to the use of soybean oil in nutraceuticals. The objective of this ... -
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 ... -
Wild halophytic species as forage sources: key aspects for plant breeding
(Wiley; British Grassland Society; European Grassland Federation, 2019-02-20)The use of wild halophytic species as forage resources in saline environments has gained increasing attention. Argentina ranks third in area of saline soils in the world, with a third of its territory showing various degrees ...
