Biochemical and molecular mechanism of abiotic stress tolerance in plants

Abstract

Plants need to acclimatize with sudden changing environment for their adaptation. Plant community, as a whole, is the primary producer in our ecosystem, therefore versatile in nature. In its differential habitats, plants need to cope up with environmental (abiotic) stresses like heavy metals, heat, cold, drought, acidic soil, and various nutrient deficiencies. Plants have their genetic ability to overcome the challenges of different environmental stresses through complex metabolic pro- cesses. There are numerous reports in connection with biochemical and molecular mechanisms in response to abiotic stresses. However, it is difficult to correlate the different molecular mechanisms involved pertaining to abiotic stresses in plants. Therefore, in this article, an attempt has been made to draw a systematic relation- ships of different biochemical and molecular processes involved in plant system during environmental stresses.
