Phylogenetic analysis of ZmPP2C, a protein phosphatase 2C gene from Zea mays

ZmPP2C was a protein phosphatase 2C gene that we cloned from maize roots. It is an important type of protein phosphatase family. AlignX is a software which can compare homology of many proteins or nucleic acids and search homologous fragments or different bases in high similarity sequences. This paper makes use of the AlignX program to visualize and analyze DNA sequences of ZmPP2C comparing with other protein phosphatase 2C from Arabidopsis and other plants. Based on the AlignX program, we map the phyligenetic trees and analyse them. The conclusion shows that ZmPP2C has high homology with MPC9 from Mesembryanthemum crystallinum Linn (ice plant). And in another phylogenetic analysis of ZmPP2C and all PP2Cs from Arabidopsis thaliana (Arabidopsis), ZmPP2C has high homology with Group F, which was classified by enzyme-catalyzed region.
