Phylogenetic analysis of BBX genes in grapevine and pear. a The full-length amino acid sequences of BBX proteins from grapevine (VvBBX) and pear (PbBBX) were aligned by ClustalX, and the phylogenetic tree was constructed using the neighbor-joining method with1000 bootstrap replicates by MEGA5.0. b, c, d The trees shown were based on the alignments of the protein sequences of the B-Box 1 domain, B-Box 2 domain and CCT domain, respectively. The bootstrap values were indicated at each node. The members marked in black triangle contain two B-BOX and one CCT domains
