摘要
由干旱、低温和高盐等引起的渗透胁迫是影响包括细菌、酵母和高等植物在内的多种生物生长和发育的主要环境因子。生物体自身已进化出多种机制以应答这些胁迫。文中介绍了细菌和酵母中响应渗透胁迫的双组分信号系统,对拟南芥中响应渗透胁迫的重要分子ATHK1的研究进展作了简要综述,并简单讨论了ATHK1在拟南芥逆境胁迫响应过程中的主要功能,为组氨酸激酶ATHK1的进一步合理应用提供依据。
Osmotic stress caused by drought, low temperature and high salinity is the major enviromnental factor that significantly restricts the growth and development of bacteria, yeast and higher plants. Living things have evolved lots of mechanisms to respond to these stresses. This paper firstly described the two-component systems in bacteria and yeast, provided a brief overview of ATHK1, and discussed major functions of ATHK1 in responding to these stresses. It is expected that this study will provide certain basis for further reasonable application of Histidine Kinase ATHK1.
