From: New insights into the evolution of SPX gene family from algae to legumes; a focus on soybean
Phylogenetic analysis of 218 SPX containing proteins from 19 plant species. The phylogenetic tree was constructed using the Maximum Likelihood method. The SPX genes of Arabidopsis, rice, wheat, rapeseed, M. truncatula, soybean, and common bean are represented with At, Os, Ta, Bna, Mt, Gm, and Pv abbreviations, respectively. Other species are named based on their Gene IDs and their domains. Four different clades are marked in colors: SPX (green), RING (brown), MFS (pink), and EXS (blue). Sub-clades of each clade are shown with light and dark shades of the respective colors. Five boxes show paraphyletic branches; box E comprises the outgroup species
