Post-anthesis drought stress is the most important problem affecting wheat production in dryland fields, specially in Mediterranean regions. The main objective of this research was to evaluate drought tolerance indices in dryland wheat genotypes under post-anthesis drought stress. The research was including two different experiments. In each experiment, twenty dryland bread wheat genotypes were...

trr14 is a novel protein important in trehalose (α-d-glucosyl-[1,1]-α-d-glucopyranoside) signaling in arabidopsis. in this research, we provided evidences to demonstrate that trr14 plays role in arabidopsis responses to salt and drought stress. the transgenic arabidopsis plants over-expressing trr14 under the control of camv 35s promoter were generated. transformed lines showed higher transcrip...

environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in iran. for cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. in this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...

in order to study stress tolerance indices and identifying tolerance genotypes to drought stress condition 16 genotypes of durum wheat were assessed in a randomized complete block design with four replications under two irrigated and rainfed conditions in the research station located in west of iran ilam in 2006- 2007. results showed that variation in among durum wheat genotypes under irrigated...

Continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. Using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. Thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

The plant-specific NAC transcription factors play important roles in plant response to drought stress. Here, we have compared the expression levels of a subset of GmNAC genes in drought-tolerant DT51 and drought-sensitive MTD720 under both normal and drought stress conditions aimed at identifying correlation between GmNAC expression levels and drought tolerance degree, as well as potential GmNA...

Recent advances in soybean breeding have resulted in genotypes that express the slow-wilting phenotype (trait) under drought stress conditions. The physiological mechanisms of this trait remain unknown due to the complexity of trait × environment interactions. The objective of this research was to investigate nitrogen metabolism and leaf and seed nutrients composition of the slow-wilting soybea...

in order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (opera, karaj1, karaj2, karaj3, zarfam, okapi, talayeh, licord and modena) were evaluated under two conditions (normal and drought stress) in kangavar region in the west iran in 2014-2015 growing season. this research was carried out in a split plot experiment based on completely randomized design in f...
