Ca2+ -dependent signalling processes enable plants to perceive and respond to diverse environmental stressors, such as osmotic stress. A clear understanding of the role of spatiotemporal Ca2+ signalling in green algal lineages is necessary in order to understand how the Ca2+ signalling machinery has evolved in land plants. We used single-cell imaging of Ca2+ -responsive fluorescent dyes in the ...
Water deficit is one of the most important environmental stresses limiting plant growth and crop yield. While the identification of many key factors involved in the plant water deficit response has greatly increased our knowledge about the regulation system, the mechanisms underlying dehydration tolerance in plants are still not well understood. In our current study, we investigated the roles o...
Pathogenic microbes exist in dynamic niches and have evolved robust adaptive responses to promote survival in their hosts. The major fungal pathogens of humans, Candida albicans and Candida glabrata, are exposed to a range of environmental stresses in their hosts including osmotic, oxidative and nitrosative stresses. Significant efforts have been devoted to the characterization of the adaptive ...
Histone H3 phosphorylation has been linked to various environmental stress responses and specific chromatin structure. The role of H3 phosphorylation in the osmotic stress response was investigated on the mouse mammary tumor virus (MMTV) promoter in different chromatin configurations. Hormone-dependent transcription from the MMTV promoter is repressed by osmotic stress when the promoter is inte...
Changes in dry matter and water-soluble carbohydrate components, especially fructan, were examined in the basal 25 mm of expanding leaf blades of tall fescue (Festuca arundinacea Schreb.) to assess their roles in plant response to water deficit. Water was withheld from vegetative plants grown in soil in controlled-environment chambers. As stress progressed, leaf elongation rate decreased sooner...
BACKGROUND Low salinity is one of the main factors limiting the distribution and survival of marine species. As a euryhaline species, the Pacific oyster Crassostrea gigas is considered to be tolerant to relative low salinity. The genes that regulate C. gigas responses to osmotic stress were monitored using the next-generation sequencing of whole transcriptome with samples taken from gills. By R...
In response to osmotic stress, global translation is inhibited, but the mRNAs encoding stress-protective proteins are selectively translated to allow cell survival. To date, the mechanisms and factors involved in the specific translation of osmostress-responsive genes in Saccharomyces cerevisiae are unknown. We find that the mRNA cap-binding protein Cbc1 is important for yeast survival under os...
Summer season with 30C is taken as control, where as rainy season with 20C is taken as cold stress and winter season with 15C is taken as cold adaptation. During summer season (control) The Acetyl Choline Esterase Increases, fats decreases and fatty acids increases. The fatty acids are utilized by the fish for its strenuous activity during summer. During Rainy, season due to cold stress the fat...
The yeast ATF/CREB repressor Sko1(Acr1) regulates genes that are induced upon hyperosmotic stress by recruiting the Cyc8(Ssn6)-Tup1 corepressor complex to target promoters. During hyperosmotic stress, Hog1 MAP kinase associates with target promoters, phosphorylates Sko1, and converts Sko1 into a transcriptional activator. Unexpectedly, Tup1 remains bound to target promoters during osmotic stres...
