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.
