Phylogenetic analysis of MAPKs in various species. A total of 21 MeMAPKs from cassava, 20 AtMPKs from Arabidopsis, and 15 OsMPKs from rice, 16 SlMAPKs from tomato, 26 MdMPKs from apple, and 14 CsMPKs from cucumber, were used to create the NJ tree using ClustalX 2.0 and MEGA5 with 1000 bootstrap. Branches with less than 50% bootstrap support were collapsed. Four clades were labeled as A, B, C, and D.
