摘要: PP2C是一类丝氨酸/苏氨酸残基蛋白磷酸酶,在高等植物ABA信号途径中起着重要的作用。为阐明巴西橡胶树中PP2C基因的结构与功能,本研究通过生物信息学方法,从橡胶树转录组数据库中鉴定并获得6个PP2C家族基因,均含有PP2CDF1和F2亚族。通过qRT-PCR技术对6个PP2C家族基因进行了干旱处理下的差异表达分析,发现6个基因都不同程度上响应橡胶树干旱胁迫。本研究为探究PP2C基因在橡胶树抗干旱反应机制提供了理论依据。

Abstract: PP2Cs are a group of monomeric serine/threonine protein phosphatases, which play an important role in ABA signaling pathway in higher plants. In order to elucidate the structure and function of PP2C gene in rubber tree,we used a bioinformatics approach to get six PP2C genes members from rubber tree transcription database, six HbPP2Cs all contain PP2C conserved domains.By sequence alignment and phylogenetic analysis,six HbPP2Cs were divided into four subfamilies:subfamily A, D, F1 and F2. Different expression analysis of six PP2C family genes under drought stress by qRT-PCR showed that they all response to drought stress in varying degrees.Our study provides a theoretical basis for exploring the mechanism of PP2C genes in drought resistance of rubber tree.
