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
(Universidad Nacional de Cuyo, 2011)Chloris gayana Kunth is a grass species valuable as forage which was introduced into Argentina to be used as pasture in saline soils of subtropical and warm-temperate zones, given its good adaptability to drought, salinity ... -
Involvement of nitrate reductase (NR) in osmotic stress-induced NO generation of Arabidopsis thaliana L. roots
(Elsevier, 2010-01)Nitric oxide (NO) is undoubtedly a potential signal molecule in diverse developmental processes and stress responses. Despite our extensive knowledge about the role of NO in physiological and stress responses, the source ... -
Physiological causes for decreased productivity under high salinity in Boma, a tetraploid Chloris gayana cultivar
(CSIRO Publishing, 2001)Rhodes grass (Chloris gayana Kunth) is widely cultivated in the semi-arid tropics and favoured for salt tolerance; nevertheless, productivity decreases significantly under saline conditions, especially in tetraploid ... -
Sweet corn (Zea mays L.) growth and yield are influenced by establishment methods
(South African National Biodiversity Institute, 2014-06)Six experiments were performed in the term of three years in order to explore and compare the effects of transplanting and direct sowing (DS) on sweet corn (Zea mays L.) growth, earliness and yield. Different genotypes, ... -
Decreased reactive oxygen species concentration in the elongation zone contributes to the reduction in maize leaf growth under salinity
(Society for Experimental Biology, 2004-06)Reactive oxygen species (ROS) in the apoplast of cells in the growing zone of grass leaves are required for elongation growth. This work evaluates whether salinity‐induced reductions in leaf elongation are related to altered ... -
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 ... -
Drought controls on H2O2 accumulation, catalase (CAT) activity and CAT gene expression in wheat
(Society for Experimental Biology, 2005-01)Plants co-ordinate information derived from many diverse external and internal signals to ensure appropriate control of gene expression under optimal and stress conditions. In this work, the relationships between catalase ... -
Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ... -
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 ... -
