Fig. 1From: Identification and expression analysis of expansin gene family in Salvia miltiorrhizaPhylogenetic relationships between EXP sequences. The full-length amino acid sequences of SmEXP, AtEXP, and OsEXP were used to construct the phylogenetic tree using MEGA X via the neighbor-joining (NJ) method. The value at the branch is the confidence level determined by performing 1000 bootstrap testsBack to article page
