Phylogenetic trees of GMGT and ManS orthologs involved in galactomannan biosynthesis. (A) ML phylogenetic tree of the ManS ortholog group. The complete tree is shown in Supplementary Fig. S8. The grey circle indicates the ManS ortholog of C. tetragonoloba, and the black circle indicates the ManS ortholog of C. siliqua. (B) ML phylogenetic tree of the GMGT ortholog group. The grey circle indicates the GMGT ortholog of C. tetragonoloba, and the black circle indicates the GMGT ortholog of C. siliqua.
