Plant RNA chaperones in stress response

摘要

Post-transcriptional regulation of RNA metabolism is a key regulatory process in diverse cellular processes, including the stress response of plants, during which a variety of RNA-binding proteins (RBPs) function as central regulators in cells. RNA chaperones are RBPs found in all living organisms and function by providing assistance to the correct folding of RNA molecules during RNA metabolism. Although our understanding of the role of RNA chaperones in plants is far less advanced than in bacteria, viruses, and animals, recent progress in functional characterization and determination of RNA chaperone activity of several RBPs has shed new light on the emerging roles of RNA chaperones during the stress response of plants.
