Fig. 4From: Genome-wide characterization of the GRF family and their roles in response to salt stress in GossypiumPhylogenetic analysis of GRF proteins from three Gossypium species and Arabidopsis thaliana. The phylogenetic tree was established with entire protein sequences with ML methods. The numbers on the branches indicate bootstrap support values from 1000 replications. The scale represents the units of the number of amino acid substitutions per site. The protein sequences used in the phylogenetic analysis are listed in Table 1. a-g represent seven phylogenetic cladesBack to article page
