Fig. 1From: Genome-wide identification and expression analysis of the bZIP transcription factors, and functional analysis in response to drought and cold stresses in pear (Pyrus breschneideri)Un-rooted phylogenetic tree of PbrbZIP proteins. MEGA 7 was used to construct the phylogenetic tree based on the protein sequences. iTOL (https://itol.embl.de/) was used to annotate and review the phylogenic tree. The proteins were clustered into 14 groups. Different background colors indicate the different group of the PbrbZIP proteinsBack to article page
