Hyperosmotic stress yields reprogramming of gene expression in Saccharomyces cerevisiae cells. Most of this response is orchestrated by Hog1, a stress-activated, mitogen-activated protein kinase (MAPK) homologous to human p38. We investigated, on a genomic scale, the contribution of changes in transcription rates and mRNA stabilities to the modulation of mRNA amounts during the response to osmo...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

this study was carried out to evaluate the changes in some important cell parameters under water limitation in sorghum genotypes. a factorial experiment was conducted based on randomized completely design in greenhouse, in university of mohaghegh ardabili in 2014. treatments were water stress at levels of 85, 65, 45 and 25 percent field capacity in and three genotypes of forage sorghum (kfs2, k...

In order to investigate the responses of potato plantlets under in vitro conditions to osmotic and temperature stresses, a factorial experiment was carried out in a completely randomized design with three replications. Each replicate contained a glass jar with 5 explants grown in it. The first...

barley (hordeum vulgare l.) is a model plant, as genetic and physiological studies are concerned. abiotic stresses such as drought adversely affect the growth of plants. the objective of this experiment was to identify the responsive genes to osmotic stress, using macroarray (covering 13050 genes). rna was extracted from 5 barley genotypes in stress as well as in normal conditions at 3 times of...
