Fig. 1From: Genome-wide identification and expression profiling analysis of maize AP2/ERF superfamily genes reveal essential roles in abiotic stress tolerancePhylogenetic analysis among AP2/ERF proteins of maize, rice and Arabidopsis. The phylogenetic tree was constructed using MEGA 7.0 and the numbers are bootstrap values based on 1000 iterations. The tree was divided into four clades, which contained ERF (DREB and ERF subfamily), AP2 and RAV family and the branch lines for each clade are colored consistentlyBack to article page
