Maximum likelihood phylogenetic tree of 15 BBX deduced amino acid sequences identified in the sugar beet genome. The respective domain structures of the proteins and their chromosomal locations in the sugar beet genome are given in Table S4. The bootstrap consensus tree inferred from 1,000 replicates was constructed by Mega5.2 after aligning the predicted protein sequences from 15 BvBBXs by MAFFT. The percentage bootstrap values are indicated at the branch points. Scale bar represents 0.2 amino acid substitutions per site. BvCOL1, BvCOL2, and BvCOL3 have been already published by Chia et al. (9). Best Arabidopsis homologs of uncharacterized BvBBXs are indicated in brackets.
