Gene expression varies widely in natural populations, yet the proximate and ultimate causes of this variation are poorly known. Understanding how variation in gene expression affects abiotic stress tolerance, fitness, and adaptation is central to the field of evolutionary genetics. We tested the hypothesis that genes with natural genetic variation in their expression responses to abiotic stress...

Music listening is associated with both pain- and stress-reducing effects. However, the effects of music listening in daily life remain understudied, and the psycho-biological mechanisms underlying the health-beneficial effect of music listening remain unknown. We examined the effects of music listening on pain and stress in daily life in a sample of women with fibromyalgia syndrome (FMS; i.e.,...

Pathogenic intracellular bacteria can respond to antimicrobial mechanisms of the host cell through transient activation of stress-responsive genes by alternative sigma (σ) factors of the RNA polymerase. We evaluated the contribution of the extracytoplasmic function sigma factor σ(E) for Corynebacterium pseudotuberculosis resistance to stress conditions resembling those found intracellularly dur...

the sucrose non-fermenting 1-related protein kinase 2 (snrk2) family members are plant unique serine/threonine kinases which play a key role in cellular signaling in response to abiotic stresses. the three snrk2 members including srk2d, srk2i and srk2e are known to phosphorylate major abscisic acid (aba) responsive transcription factors, abf2 and abf4, involved in an aba-dependent stress signal...

To analyze the mechanisms of salt tolerance in the halophyte Suaeda japonica, Escherichia coli was used as a host organism to undertake functional screening of cDNAs encoding proteins that may play an important role for the salt-tolerance mechanisms. A transformant expressing RelA/SpoT homolog (Sj-RSH) was found to have enhanced salt tolerance. In E. coli, RelA/SpoT controlled the amount of gua...

To unravel the molecular mechanisms of drought responses in tomato, gene expression profiles of two drought-tolerant lines identified from a population of Solanum pennellii introgression lines, and the recurrent parent S. lycopersicum cv. M82, a drought-sensitive cultivar, were investigated under drought stress using tomato microarrays. Around 400 genes identified were responsive to drought str...

Eight genes showed significant changes in expression in mice under psychophysiological stress provided by cage-restraint and water-immersion. The transcription level of most of these genes was affected in all the tissues analyzed, and some of them were responsive genes in several different stress systems. Peculiarly, the expression level of one gene, cdc2-like kinase 1 (CLK1), was reduced only ...

The diversified physiological responses in cyanobacteria under ultraviolet-B (UV-B) radiation have been broadly researched. The changes in the metabolic control mechanisms hidden behind these physiological traits still need to be further investigated. This research attempts to identify some of the internal mechanisms of several stressful phenotypes such as a decreased growth rate, an impaired p...

The transcription factor (TFs) BES1, which mediates brassinosteroid (BR) signaling, regulates plant growth and development. However, BES1 genes have not yet been reported in Tartary buckwheat. Here, ten FtBES1 were identified the buckwheat genome, they named FtBES1-1 to FtBES1-10. These divided into four groups according classification Arabidopsis thaliana. Multiple sequence alignment indicated...

Nowadays, crop insufficiency resulting from soil salinization is threatening the world. On basis that has become a worldwide problem, studying mechanisms of plant salt tolerance great theoretical and practical significance to improve yield, cultivate new salt-tolerant varieties, make full use saline land. Based on previous studies, this paper reviews damage stress plants, including suppression ...
