Fig. 2From: Genome-wide in silico identification and expression analysis of beta-galactosidase family members in sweetpotato [Ipomoea batatas (L.) Lam]Phylogenetic tree of bgal proteins in sweetpotato, and Arabidopsis. The bgal protein sequences of Arabidopsis were downloaded from the database of Arabidopsis from the NCBI database. The phylogenetic tree was constructed using MEGA 7.0 by the Maximum-Likelihood method analysis with 1000 bootstrap replications. The tree was classified into 7 different subfamilies indicated by outer rings with blue colorBack to article page
