An RNA-Seq experiment was performed using field grown well-watered and naturally rain fed cotton plants to identify differentially expressed transcripts under water-deficit stress. Our work constitutes the first application of the newly published diploid D5 Gossypium raimondii sequence in the study of tetraploid AD1 upland cotton RNA-seq transcriptome analysis. A total of 1,530 transcripts were...

the water deficit is the most important limiting non-biological factor to achieve the potential yield of crops. to evaluate the effect of silicon application on yield of millet under drought stress in field an experimental was carried out. treatments were included three irrigation regimes after 60 (non-stress), 90 (moderate stress) and 120 (severe stress) mm evaporation from evaporation pan, cl...

Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by mountain pine beetle than their healthy counterparts. In this study, we tested the hypothesis that wa...

according to the global water shortage problem, the exploring for reducing its harmful effects is very important. this experiment was conducted as split plots method based on randomized complete block design with three replicates in urmia university research field during growing season of 2013-14. water deficit stress as main plot consisted of three levels (irrigation when soil moisture reached...

The effects of irrigation, dry farming and drought treatments on the activities of antioxidant enzymes including superoxide dismutase, ascorbate peroxidase, catalase and peroxidase in barley leaves at different generative growth stages under field conditions were investigated. Three senescence parameters including chlorophyll, total soluble protein and rubisco large subunit protein loss, were a...

Plants overcome water deficit conditions by combining molecular, biochemical and morphological changes. At the molecular level, many stress-responsive genes have been isolated, but knowledge of their physiological functions remains fragmentary. Here, we report data for RD20, a stress-inducible Arabidopsis gene that belongs to the caleosin family. As for other caleosins, we showed that RD20 loca...

We investigated the role of GlyBet (100 mM) applied exogenously in alleviating water-deficit induced stress in indica rice cv. Pathumthani 1 (PT1). Exogenous GlyBet increased proline concentration in the leaf tissues of water deficit stressed plants depend on a degree of soil water content (SWC), especially at severe water deficit (25% SWC). Foliar GlyBet (100 mM) significantly enhanced chlorop...

introduction lentil (lens culinaris medik.) is a good source of protein, carbohydrates as well as minerals, vitamins and unsaturated fatty acids as such it plays an important role in the human diet and cultivated worldwide. water shortage is one of the most important abiotic factors that can limit morphological, physiological, yield, and plant distribution. legumes such as lentil are highly sen...

to investigate the effects of regulated deficit irrigation (rdi) on the growth, yield and quality of ‘yali’ pears, field experiments for c (fully watered control), ew [early withholding of irrigation, water stress from pullulation to 25 days after flower bloom (dafb)], mw (mid-growth withholding of irrigation, water stress from 25 dafb to 80 dafb), and lw (late withholding of irrigation, water ...
