Fig. 3From: Genomic identification and expression profiling of WRKY genes in alfalfa (Medicago sativa) elucidate their responsiveness to seed vigorPhylogenetic tree of WRKY members in alfalfa and Arabidopsis. MsWRKY and AtWRKY protein sequences were aligned with ClustalW, and a phylogenetic tree was constructed with MEGA7.0 using the neighbor-joining method and 1000 bootstrap replicates. The members were divided into Groups I, II, and III, and Group II was further divided into Subgroups IIa, IIb, IIc, IId, and IIeBack to article page
