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 ... -
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 ... -
Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids
(Wiley; Scandinavian Plant Physiology Society, 2016-08)Sweet sorghum has a photosynthetic system which is highly sensitive to cold stress and hence strongly limits its development in temperate environments; therefore, the identification of key exploitable cold tolerance traits ... -
Differential response of Trichloris ecotypes from different habitats to drought and salt stress
(Springer, 2020-08-05)Native plant genetic resources have evolved from long processes of natural selection and adaptation to specific environments, and have developed tolerance to various stresses prevailing in their natural habitats via adaptive ... -
Differential salt-stress response during germination and vegetative growth in in vitro selected somaclonal mutants of Cenchrus ciliaris L.
(2013-07)Four somaclonal mutants (S1, S4, S6 and M10) and their parental Cenchrus ciliaris L. cultivar Biloela were characterized under salinity conditions at germination and vegetative growth stages. Seeds of all somaclonal mutants ... -
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 ... -
Diversity and stress tolerance in rhizobia from Parque Chaqueño region of Argentina nodulating Prosopis alba
(Springer, 2013-11)The aim of this work was to investigate the genetic diversity, symbiotic effectiveness, drought tolerance, and indole acetic acid production of indigenous rhizobial populations in the Parque Chaqueño of Argentina able to ... -
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 ... -
Drought induces distinct growth response, protection, and recovery mechanisms in the maize leaf growth zone
(2015-10)Drought is the most important crop yield-limiting factor, and detailed knowledge of its impact on plant growth regulation is crucial. The maize (Zea mays) leaf growth zone offers unique possibilities for studying the ... -
Drought stress tolerance of Prosopis chilensis and Prosopis flexuosa species and their hybrids
(Springer, 2013-02)Natural hybridization commonly produces individuals with intermediate morphological and genetic characteristics, but their response to environmental stress is still uncertain, with some studies showing that transgressive ... -
Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
(Elsevier, 2018-11)Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ... -
Ecophysiological mechanisms underlying the positive relationship between seed protein concentration and yield in soybean under field heat and drought stress
(Wiley, 2024-06)A positive relationship between protein concentration and yield has been documented in different combinations of genotype and environment, often under potential conditions. However, the ecophysiological bases underlying ... -
Editorial: Legumes and their microbiome in climate change mitigation
(Frontiers Media, 2023-06-12)Climate change accelerates or enhances the incidence of a variety of abiotic and biotic stresses on agricultural and forest productivity. By changing different aspects of agriculture management, we can lower the risk of ... -
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 ... -
Environmental influence on reproductive traits of buffel grass facultative apomictic genotypes and its implication in plant breeding
(Wiley, 2023-10-04)Cenchrus ciliaris L., a perennial C4 grass, is one of the most widely used forage species in warm and dry regions worldwide. The widespread use of the cultivar Texas raises concerns about genetic homogeneity and vulnerability. ... -
