Fig. 1From: Genome-wide identification and characteristic analysis of the downstream melatonin metabolism gene GhM2H in Gossypium hirsutum L.Two rooted phylogeny trees constructed using MEGA-7 by the Neighbor-Joining (NJ) method. Bootstrap values (above 50%) from 1000 replicates are indicated at each node. A Phylogenetic relationship of 1185 M2H genes identified from 4 plants. B Phylogenetic relationship of the 880 identified M2H genes from four Gossypium hirsutumBack to article page
