doi:10.13560/j.cnki.biotech.bull.1985.2016.10.008

Abstract

Abstract: Cold stress is one of the major environmental factors that affect the geological distribution and seasonal growth of the plants. Being exposed to low non-freezing temperature would increase plants’resistance to freezing temperature by a process called cold acclimation. During cold acclimation,plants sense the environmental low temperature,initiate cold signal transduction pathways and change the expression of genes that are critical for plants to survive the freezing temperature. In this review,we focused on recent progresses regarding our understanding of cold signal transduction mechanisms,which including the newly discovered cold signaling components CHILLING-TOLERANCE DIVERGENCE 1（COLD1）and OPEN STOMATA1（OST1）;transcriptomic studies of C-REPEAT BINDING FACTORS （CBFs）triple mutant created by CRISPR/Cas9 technology and proteomic study of early cold regulated proteins etc. Based on these results,a cold signal transduction model is summarized.

Key words: cold stress, cold acclimation, signal transduction, transcriptome, proteome
