Phylogenetic tree of GeRAVs and other plant RAV proteins. The RAVs used in the phylogenetic tree analysis were from three dicot species (Gelsemium elegans, Glycine max, and Arabidopsis thaliana) and three monocot species (Triticum aestivum, Oryza sativa, and Zea mays) [33,34,35]. The GenBank accession numbers of all RAV homologous proteins were listed in Table S5. Groups I-V were marked in blue, pink, green, purple, and orange, respectively
