Calcium-Mediated Abiotic Stress Signaling in Roots
Roots are subjected to a range of abiotic stresses as they forage for water and nutrients. Cytosolic free calcium is a common second messenger in the signaling of abiotic stress. In addition, roots take up calcium both as a nutrient and to stimulate exocytosis in growth. For calcium to fulfill its multiple roles must require strict spatio-temporal regulation of its uptake and efflux across the ...
متن کاملTranscription Factor-Mediated Abiotic Stress Signaling in Rice
Abiotic stresses are the major cause that limits productivity of crop plants worldwide. Plants respond to these stress conditions at physiological and molecular levels. At the molecular level, the expression of thousands of genes is altered in response to various abiotic stress conditions. Several studies have been performed to find out the role of these genes in abiotic stress signaling. Howev...
متن کاملAbiotic Stress Signaling and Responses in Plants
As sessile organisms, plants must cope with abiotic stress such as soil salinity, drought, and extreme temperatures. Core stress-signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing. Stress signaling regulates proteins critical for ion and water transport and for metabolic and gene-express...
متن کاملAbiotic Stress Signaling in Plants–An Overview
Abiotic stress factors [such as salinity, water availability (less or excess water), temperature extremes (freezing, cold, or high), metal/metalloids, nutrient stress, etc.] are basically severe menaces to the global agriculture, restricting the crop plants from reaching their full genetic potential and causing significant yield losses worldwide. In general, stresses are complex and multigenic ...
متن کاملReactive oxygen signaling and abiotic stress.
Reactive oxygen species (ROS) play a dual role in plant biology acting on the one hand as important signal transduction molecules and on the other as toxic by-products of aerobic metabolism that accumulate in cells during different stress conditions. Because of their toxicity as well as their important signaling role, the level of ROS in cells is tightly controlled by a vast network of genes te...
