Chromatin-Based Epigenetic Regulation of Plant Abiotic Stress Response
Plants are continuously exposed to various abiotic and biotic factors limiting their growth and reproduction. In response, they need various sophisticated ways to adapt to adverse environmental conditions without compromising their proper development, reproductive success and eventually survival. This requires an intricate network to regulate gene expression at transcriptional and post-transcri...
متن کاملPlant responses to abiotic stress: The chromatin context of transcriptional regulation.
The ability of plants to cope with abiotic environmental stresses such as drought, salinity, heat, cold or flooding relies on flexible mechanisms for re-programming gene expression. Over recent years it has become apparent that transcriptional regulation needs to be understood within its structural context. Chromatin, the assembly of DNA with histone proteins, generates a local higher-order str...
متن کاملEditorial: ROS Regulation during Plant Abiotic Stress Responses
Plants frequently encounter a combination of abiotic stresses in their natural habitats. Abiotic stresses, including drought, salt, cold, heat, and heavy metal etc., modulate phytohormone metabolism and enhance expression level of transcription factors which activate stress responsive genes. During plant stress response, reactive oxygen species (ROS) act as important molecules and play pivotal ...
متن کاملAbiotic stress responses in plant roots: a proteomics perspective
Abiotic stress conditions adversely affect plant growth, resulting in significant decline in crop productivity. To mitigate and recover from the damaging effects of such adverse environmental conditions, plants have evolved various adaptive strategies at cellular and metabolic levels. Most of these strategies involve dynamic changes in protein abundance that can be best explored through proteom...
متن کاملRegulation of abiotic stress responses in plant by micro RNA: An Overview
Abiotic stress is one of the primary causes of crop losses worldwide. Plants are sessile organisms, so they have to come up with various adverse environmental conditions. The expression of several genes are up regulated and down regulated in response to stress. Micro RNAs play vital role in regulating the expression of most of the genes during stress, these are small non-coding RNA molecule of ...
