Abiotic 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...

Abiotic Stress in Plants and Metabolic Responses

Role of NO in H2O2 regulating responses against temperature and ultraviolet induced oxidative stress in plants

A range of abiotic environmental stresses results in H2O2 generation, from a variety of sources and it has many essential roles in plant metabolism but at the same time, accumulation related to virtually any environmental stress is potentially damaging. NO, another stress responsive molecule, is gaining high attention as a regulator of diverse physiological and biochemical processes in plant sc...
