Plants have evolved to have sophisticated adaptation mechanisms to cope with drought stress by reprograming transcriptional networks through drought responsive transcription factors. NAM, ATAF1-2, and CUC2 (NAC) transcription factors are known to be associated with various developmental processes and stress tolerance. In this study, we functionally characterized the rice drought responsive tran...

Sesame has great potential as an industrial crop but its production is challenged by drought and salt stresses. To unravel the genetic variants leading to salinity and drought tolerances at the germination stage, genome-wide association studies of stress tolerance indexes related to NaCl-salt and polyethylene glycol-drought induced stresses were performed with a diversity panel of 490 sesame ac...

to breaking dormancy as well as the effect of light, temperature, salinity and drought stress on germination of cutleaf mignonette seeds, experiments were conducted at the research laboratory of birjand faculty of agriculture in 2009. immersion in sulfuric acid (96%) for 30 seconds under continuous dark regime resulted in the highest germinability (73%) and the lowest germination (8%). was obse...

fennel (foeniculum vulgare mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds andmedicinal uses. as the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mm nacl), nitrogen and iron deficiency (0 n, 0.5 n of hoagland’s solution, 0 fe and 0.5 fe ofhoagland’s solution), 2°c cold (2, 3 and 4 h) and drought (3, 5...

aeluropus lagopoides is a salt and drought tolerant grass from poaceae family, distributed widely in arid regions. there is almost no information about the genetics or genome of this close relative of wheat that stands harsh conditions of deserts. differential display amplified fragment length polymorphism (dd-aflp) led to the improvement of a non-radioactive method for which many parameters we...

We isolated and examined two endophytic fungi for their potential to secrete phytohormones viz. gibberellins (GAs) and indoleacetic acid (IAA) and mitigate abiotic stresses like salinity and drought. The endophytic fungi Phoma glomerata LWL2 and Penicillium sp. LWL3 significantly promoted the shoot and allied growth attributes of GAs-deficient dwarf mutant Waito-C and Dongjin-beyo rice. Analysi...

Drought, one of the most important abiotic stress factors limiting biomass, significantly reduces crop productivity. Salinization also affects the productivity of both irrigated and rain-fed wheat crops. Species of genus Aegilops can be considered crop wild relatives (CWR) of wheat and have been widely used as gene sources in wheat breeding, especially in providing resistance to pests and disea...

This study aimed to select and characterize bacterial strains with multiple plant growth promotion properties able to tolerate drought and salinity stress in order to improve plant growth performance under abiotic stresses. Plant growth promoting activities were evaluated in 106 bacterial strains isolated by soil, compost, lignocellulosic biomasses and food matrices. Two strains A. chroococcum ...
