Plant Biology: New Insight into How Roots 'Mask Up'
(Cell Press, 2021-03-08)Extra- and trans-cellular barriers are essential for root function under even mild stress. New research shows that establishing both the lignin and suberin barriers in the Arabidopsis endodermis requires phenylpropanoid ... -
Contrasting adaptive responses to cope with drought stress and recovery in Cenchrus ciliaris L. and their implications for tissue lignification
(Wiley, 2020-11-12)Cenchrus ciliaris L. is a widely used species for cattle feed in arid and semi-arid regions due to good forage value and known tolerance to drought conditions. Here, we provide insights to adaptive responses of two contrasting ... -
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 ... -
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 ... -
Agronomic and molecular characterization of Chloris gayana cultivars and salinity response during germination and early vegetative growth
(CIAT, 2019-01)Chloris gayana is a warm-season grass, often cultivated in areas where soil salinity is a major constraint for forage production. Five cultivars (2 unselected populations and 3 synthetic varieties) were evaluated through ... -
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 ... -
Morpho‐physiological traits associated with drought responses in soybean (Glycine max L.)
(2020-08-26)Drought is currently a major constraint to soybean production worldwide and is becoming more widespread due to increased aridity and warmer temperatures in the context of global climate change. In this context, breeding ... -
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 ... -
Interactions between soybean, Bradyrhizobium japonicum and Soybean mosaic virus: the effects depend on the interaction sequence
(2019-06-25)The symbiotic interaction between soybean and nitrogen-fixing rhizobia can lead to plant growth promotion and induced systemic responses. Symbiotic interactions may increase tolerance/resistance to abiotic/biotic stress ... -
New insights into the molecular basis of induced resistance triggered by potassium phosphite in potato
(2019-11-12)This work aimed to provide data about the molecules involved in induced resistance mediated by potassium phosphite (KPhi) in potato. To achieve these, we performed microarray analysis to determine the changes in gene ... -
Identificación y caracterización de los hongos micorrícicos arbusculares autóctonos en simbiosis con prosopis alba y los mecanismos fisiológicos / bioquímicos relacionados con la tolerancia a sequía
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2019)Prosopis alba Grisebach (algarrobo blanco) es una de las especies más importantes en el ecosistema natural del Chaco Occidental Semiárido de Argentina. Entre las estrategias para asegurar el establecimiento y el adecuado ... -
Salt tolerance in Argentine weathgrass [Elymus scabrifolius (Döll) J.H. Hunz.] is related to shoot sodium exclusion
(Wiley, 2020-06)This is the first report about Na and K fluxes and heritability of Na exclusion in the Elymus genus. Argentine wheatgrass (Elymus scabrifolius ) is an important forage genetic resource for saline environments. A previous ... -
Abordajes fisiológicos para el estudio del estrés abiótico en plantas. Disertaciones y protocolos
(Ediciones INTA, 2019)El libro "Abordajes fisiológicos para el estudio del estrés abiótico en plantas. Disertaciones y protocolos" de Ediciones INTA es producto del taller de formación dictado en el Instituto de Fisiología y Recursos Genéticos ... -
Elongation growth in leaf blades of Chloris gayana under saline conditions
(Elsevier, 2003)In Chloris gayana, salinity-associated yield decreases are due mainly to leaf area reductions. To understand the physiological basis for such reduction, the effects of salinity were studied on the spatial and temporal ... -
Leaf expansion in grasses under salt stress
(Elsevier, 2009-07)Restriction of leaf growth is among the earliest visible effects of many stress conditions, including salinity. Because leaves determine radiation interception and are the main photosynthetic organs, salinity effects on ... -
Genetic variability for responses to short‐ and long‐term salt stress in vegetative sunflower plants
(Wiley, 2012-12)Sunflower (Helianthus annuus L.) has been rated as moderately salt‐resistant, and variability for salt resistance has been detected within this crop. However, variability in salt‐resistance mechanisms has not been assessed. ... -
Salinity induced anatomical and morphological changes in Chloris gayana Kunth roots
