植物低温信号的感知、转导与转录调控
Signal Perception, Transduction and Transcriptional Regulation during Cold Stress in Plant
摘要
Abstract
Cold is one of the key environmental stressors which affect plant growth and development. The response process of plant to cold is a complex procedure. It includes several steps, such as low temperature signal perception, signal transduction, transcription regulation. Cold can be perceived by plasma membrane either due to changes in membrane fluidity or with the help of sensors like Ca2+ permeable channels, histidine kinases, receptor kinases and phospholipases. Cold signal transduction includes calcium signal pathway and other signal pathways, of which calcium signal pathway is an important pathway of cold response process in plant. In this pathway, cytosolic Ca2+induced by cold can be recognized and transduced by CDPKs, phoshatase and MAPKs. Other signal pathways are mainly related to ABA. Cold signal will at last switch on CBF and non-CBF independent transcriptional cascade, thus to improve plant resistance to cold.关键词
