Fig. 2From: Classification of barley U-box E3 ligases and their expression patterns in response to drought and pathogen stressesDomain structures and phylogenetic analysis of Class II genes in barley. a. Domain structures of 23 Class II PUB genes. Green box, U-box domain; sky blue box, ARM repeat domain; blue box, Heat domain. b. Phylogenetic analysis of 23 Class II PUB genes in barley. Brown dot, subclass a; blue dot, subclass b. c. Full-length amino-acid sequences of ARM repeat domain were aligned using the Clustal X2 software. The tree was constructed by neighbor-joining method after bootstrap analysis for 1000 replicates [11]Back to article page
