Salt tolerance variability among stress‐selected Panicum coloratum cv. Klein plants
(Wiley; British Grassland Society; European Grassland Federation, 2016-11)This work assessed intracultivar variability for salt tolerance within Panicum coloratum cv. Klein, explored some physiological parameters potentially associated with it and evaluated the contribution of cell division and ... -
Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils
(Wiley; British Grassland Society; European Grassland Federation, 2017-12)Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
Interspecific hybridization improves the performance of Lotus spp. under saline stress
(Elsevier, 2019-06)Salinity is one of the most frequent limiting conditions in pasture production for grazing livestock. Legumes, such as Lotus spp. with high forage quality and capable of adapting to different environments, improves pasture ... -
Malondialdehyde content as a potential biochemical indicator of tolerant Cenchrus ciliaris L. genotypes under heat stress treatment
(Wiley, 2012-09)Buffel grass (Cenchrus ciliaris L.) is an important forage grass in arid and semiarid regions. As part of a genetic improvement programme, four genotypes [Biloela (Bl), Americana (Am), Texas (Tx) and Sexual (Sx)] were ... -
Diversidad e infectividad de hongos micorrícicos arbusculares nativos provenientes de algarrobales del Parque Chaqueño argentino con características edafoclimáticas contrastantes
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2018)En ambientes severos, la presencia de hongos micorrícicos arbusculares (HMA) es clave para la supervivencia de las plantas y el balance ecosistémico. El objetivo de este trabajo fue caracterizar los hongos micorrícicos ... -
Day length modulates precocity and productivity through its effect on developmental rate in Origanum vulgare ssp.
(Elsevier, 2017-04)In Origanum spp. knowledge about mechanisms controlling development and growth in response to environmental factors such as temperature and photoperiod, is critical to improve management practices and varietal selection ... -
A bacterial endophyte from apoplast fluids protects canola plants from different phytopathogens via antibiosis and induction of host resistance
(American Phytopathological Society, 2019-03)Endophytic bacteria colonize inner plant tissues and thrive at the apoplast, which is considered its main reservoir. Because this niche is the place where the main molecular events take place between beneficial and pathogenic ... -
Assessing spatial genetic structure from molecular marker data via principal component analyses: a case study in a Prosopis sp. fores
(Scientific Research Publishing, 2014-01)Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, ... -
Morphological diversity of populations of the genus Prosopis in the semiarid Chaco of northern Cordoba and southern Santiago Del Estero
(Scientific Research, 2013-11)The objective of this study consisted in the characterization of morphological variability presented in the Prosopis population in the corridor that unites the semiarid with the arid region in Argentina. In this region, ... -
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 ... -
Analysis of genetic variability in in vitro regenerated buffelgrass plants through issr molecular markers = Análisis de variabilidad genética en plantas regeneradas in vitro de buffelgrass mediante marcadores moleculares issr
(Universidad Nacional de Cuyo, 2018)Genetic variability can be generated through in vitro culture via somaclonal variation. This tool can be potentially useful in a breeding program involving apomictic buffelgrass genotypes. The aim of this work was to ... -
Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom
(Taylor & Francis, 2013)Sugars are part of an integrated redox system, since they are key regulators of respiration and photosynthesis, and therefore of the levels of reducing power, ATP and ROS. These elements are major determinants of the ... -
