Heat Shock Proteins: Classification, Functions and Expressions in Plants during Environmental Stresses.

Abstract

Heat shock proteins assist in folding proteins that is a basic cellular constituent responsible for various crucial functions including protein assembly, transportation, folding in normal conditions and denaturation of proteins in stress and in other cellular function. Abiotic factors like increased temperature, drought and salinity negatively affect reproduction and survival of plants. Plants (HSPs), as chaperones, have crucial part in conversing biotic and abiotic stress tolerance. Plants react towards critical changes through biochemical, growth, and physiological mechanisms included expression of stress-reactive proteins, which are regulated by interconnected signaling cascades of transcription factors including heat stress TFs.
