摘　　要：锌指蛋白是转录因子的一种,因其具有指状结构特征且能结合Zn2+而得名。植物C2H2型锌指蛋白是研究较多、较为明确的一种,大多包含特有的QALGGH保守结构。该蛋白广泛参与到植物的生长发育和逆境胁迫信号转导过程中。本研究主要综述了植物C2H2型锌指蛋白的结构、功能、分类及逆境相关的作用机制,概括了C2H2型锌指蛋白在参与植物非生物和生物胁迫耐受性的研究成果,并对其进一步的深入研究进行了展望,为将来利用锌指蛋白基因提高作物抗逆性提供较为全面的资料。Zinc finger protein is a kind of transcription factor,which was named due to its finger structure and being able to combine with Zn2+.Plant C2H2 type zinc finger proteins are studied more clearly and mostly contain unique and conserved amino acids(QALGGH).These proteins are widely involved in the process of signal transduction on plant growth and stressed environments.This paper mainly reviews the structure and function,family classification and stress-related mechanism on plant C2H2 zinc finger proteins and research achievements in response to abiotic and biotic stress,and puts forward to some prospects for deep investigation,which would provide a comprehensive understanding for improving the plant multi-tolerance by using C2H2 type zinc finger protein gene resources.
