Figure 1From: Maize protein phosphatase gene family: identification and molecular characterizationPhylogenetic relationships of ZmPPs. An un-rooted NJ tree is made based on the catalytic domain sequences of ZmPPs. The whole PP gene family is divided into different classes, PP2C, PP2A, PTPs, PTPL, CDC25, and LMWP. PP2C class is further subdivided into different classes (A-K). Scale bar represents 0.1 amino acid substitutions per site.Back to article page
