Fig. 2From: Identification and analysis of glutathione S-transferase gene family in sweet potato reveal divergent GST-mediated networks in aboveground and underground tissues in response to abiotic stressesPhylogenetic tree and subfamily classification of GST proteins from sweet potato, Ipomoea nil, Ipomoea trifida, and Arabidopsis thaliana. The unrooted tree was constructed based on multiple sequence alignment of full-length protein sequences using Muscle program by MEGA 7.0 by the Maximum Likelihood (ML) method. In total, 42, 43, 74, and 55 full-length GST proteins from sweet potato, I. nil, I. trifida, and A. thaliana, respectively, were included. The percentage bootstrap scores which >50 are indicated on the nodes. The major phylogenetic subfamilies are illustrated as different color branchesBack to article page
