Metabolomics analysis of wild type Arabidopsis thaliana plants, under control and drought stress conditions revealed several metabolic pathways that are induced under water deficit. The metabolic response to drought stress is also associated with ABA dependent and independent pathways, allowing a better understanding of the molecular mechanisms in this model plant. Through combining an in silic...

twenty five durum wheat lines were evaluated under drought stress and non-stress conditions employing randomized complete block design of 4 replications. significant differences were observed among the lines for most traits in either stress or non-stress conditions. correlation analysis under non-stress conditions indicated that grains per spike and number of spikes per m2 and while under stres...

ABA is a central player in plants response to drought stress. How variable levels of ABA under short-term versus long-term drought stress impact assimilation and growth in crops is unclear. We addressed this through comparative analysis, using two elite breeding lines of barley that show senescence or stay-green phenotype under terminal drought stress and by making use of transgenic barley line...

to study of genetic diversity of rapeseed genotypes using multivariate methods under normal and drought stress conditions, 16 genotypes were evaluated using a randomized complete blocks design with three replications in razi university in 2007-08 cropping season. factor analysis under normal condition showed that nine factors explained 89.05 percentage of total data variation, and under drought...

introduction drought stress is one of the most important abiotic stresses all around the world. the aim of breeding studies and breeding for resistance to drought is that breeders seek to identify varieties and genetic resources to drought resistant and comparison of drought resistance among the varieties and the introduction of superior varieties to farmers. drought or imbalance between supply...

the aims of this study were to assess the effects of drought stress on peroxidase (pod), superoxide dismutase (sod) and catalase (cat) activities as well as free proline content and growth parameters of pistacia khinjuk seedlings under drought stress. therefore, the one-year seedlings of pistacia khinjuk subjected to water stress (25%, 50%, 75%, and 100% field capacity) for 8 months in greenhou...

introduction major cultivated cotton regions of iran are located in dry and semiarid climates, therefore water deficiency or drought stress is inseparable part of cotton production systems in these regions. so identification and introduction of drought tolerant cotton genotypes is crucial. showed that water stress decreased plant growth rate, leaf area and finally photosynthesis in cotton. in a...

It is generally accepted that dioecious plants occur more frequently in dry and nutrient-poor habitats, suggesting that abiotic stress factors could contribute to evolution of dioecy from hermaphrodite. Therefore, experimental investigations on the responses of subdioecious species, a special sexual system comprising male, female, and hermaphrodite plants, to abiotic stress factors could quanti...
