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 ... -
Bacillus subtilis ALBA01 alleviates onion pink root by antagonizing the pathogen Setophoma terrestris and allowing physiological status maintenance
(Springer, 2020)The soil-borne pathogen Setophoma terrestris is the causal agent of pink root of onion, one of the most challenging diseases in onion production. Conventional approaches for managing the disease like solarization, soil ... -
Evolutionary insights into FYVE and PHOX effector proteins from the moss Physcomitrella patens
(Springer, 2020-02)Phosphatidylinositol 3-phosphate (PtdIns3P) is a signaling phospholipid, which regulates several aspects of plant growth and development, as well as responses to biotic and abiotic stresses. The mechanistic insights ... -
Caracterización fenotípica y genotípica de germoplasma de Panicum coloratum L var. coloratum para la tolerancia a la salinidad
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2014)Los cultivares de Panicum coloratum son poblaciones estabilizadas que presentan un cierto grado de variabilidad intracultivar. Plantas individuales provenientes de pasturas establecidas en suelos salinos, afectados además ... -
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 ... -
Inducción de variabilidad genética para tolerancia a estreses abióticos mediante técnicas de cultivo in vitro en Cenchrus ciliaris L.
(Universidad Internacional de Andalucía, 2011)El presente trabajo está enmarcado en un proyecto nacional del Instituto Nacional de Tecnología Agropecuaria (INTA) relacionado con la introducción, caracterización y mejoramiento de especies forrajeras subtropicales. En ... -
Reductions in Maize Root-tip Elongation by Salt and Osmotic Stress do not Correlate with Apoplastic O2•− Levels
(Oxford Academic Press, 2008-10)Background and Aims: Experimental evidence in the literature suggests that O2•− produced in the elongation zone of roots and leaves by plasma membrane NADPH oxidase activity is required for growth. This study explores ... -
Evaluación morfológica del cultivar de buffelgrass “Lucero INTA-PEMAN” en condiciones de sequía
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)En la búsqueda de nuevos cultivares nacionales mejor adaptados a las restricciones edafo-climáticas presentes en el noroeste argentino, principalmente estrés por sequía y salinidad, un híbrido de buffelgrass (Cenchrus ... -
Redox systemic signaling and induced tolerance responses during soybean–bradyrhizobium japonicum interaction: involvement of nod factor receptor and autoregulation of nodulation
(Frontiers Media, 2019-02)The symbiotic relationship between legumes and nitrogen-fixing rhizobia induces local and systemic responses, which ultimately lead to nodule formation. The autoregulation of nodulation (AON) is a systemic mechanism related ... -
Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ... -
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 ... -
Silencing of the tomato phosphatidylinositol‐phospholipase C2 (SlPLC2) reduces plant susceptibility to Botrytis cinerea
