摘要: 植物抗逆研究已有很大进展,但传递各种外界刺激的信号通路仍未可知,目前已有一些研究发现很多环境刺激与钙_钙调素系统有关。Ca2+信号系统是很重要的一种信号途径,CaM是目前已知的胞内Ca2+信号受体中最重要的一种,参与了多种生理活动的调节。在热激领域中,研究者已提出Ca2+ CaM系统可能参与了热激反应,在基因调节水平、转录水平、蛋白水平均有Ca2+和CaM参与热激的证据。其它环境刺激也能引起植物体内Ca2+和CaM的一系列变化。这为研究各种环境刺激可能的信号通路提供了基础和依据。

Abstract: Great progresses have been made in the research of plant stress-resistance, but which signal transduction pathways are activated responding to environment stimulation are still unknown. Some researches have found out that many stimuli have something to do with Ca2+ and calmodulin. Ca2+ signal system is a very important transduction pathway, and calmodulin is the most important known r eceptor of intracellular Ca2+, which is involved in regulation of many physiological activities. Research workers have evidences in gene regulation level, transcription level, protein level that suggest Ca2+ and calmodulin are involved in heat shock reaction. Other environment stimulations also can lead to a series of changes of Ca2+ and calmodulin. These provide the foundation and basis for studying the probable signal transduction pathways of nvironment stimulation.
