Abstract:

Cold shock proteins (CSPs) are nucleic acid-binding proteins containing a cold shock domain (CSD), which are highly conserved in bacteria, plants and animals. They play a critical role for transcription, translation, development and stress responses by the RNA chaperones function. In this review, the progress of plant cold shock proteins were described from the structure, regulation of gene expression, function and the prospects of application research.

Key words: cold shock protein; cold acclimation; cold shock domain; stress response
