Phylogenetic tree of the galacturonosyltransferase (GAUT) gene family

a. Neighbor-joining phylogenetic tree of galacturonosyltransferase (GAUT) genes from eight species. b: Neighbor-joining phylogenetic tree of galacturonosyltransferase (GAUT) family form the four cotton species. They comparised three types of protein sequences by multiple sequence alignment of the 187 GAUT proteins for eight species. From the four cotton species, GAUT gene family were classified into GAUT-A (62 proteins), GAUT-B (38 proteins), and GAUT-C (31 proteins)
