The B-Box Family of Proteins from Arabidopsis Have Two Distinct B-Box Domains. Motif logos (Schneider and Stephens, 1990; Crooks et al., 2004) of protein alignments of B-box B1 (A) and B2 (B) show differences. Conservation of residues across all proteins is shown by height of each letter; a position with all like residues has a bit score of 4. The 38 conserved residues of B1 and B2 are shown; see Table 1 for individual coordinates of each B-box motif. B1 is more conserved, containing 12 out of 38 residues that are seen in 95% of the 32 family members. B2 shows seven amino acids with 95% conservation. The conserved residues of B2 are also found conserved in B1.

Phylogenetic Analysis of the Arabidopsis B-Box Family. Full-length proteins of the 32 B-box members were aligned using MUSCLE (maxiters = 16) (Edgar, 2004). Multiple alignments were viewed and realigned using SeaView (Galtier et al., 1996). MrBayes (Huelsenbeck and Ronquist, 2001) was used to construct a Bayesian inference phylogenetic tree with 1,000,000 generations. Bayesian posterior probability values are displayed on the tree as percentages, and if differing values were seen between the two independently run trees, both are displayed. This phylogeny was used to order B-box genes to provide a uniform naming terminology. For full-length protein sequences used and the multiple alignments, see Supplemental Data Set 1 (FASTA format) and Supplemental Figure 1 (alignment) online.

Structure Classification of the B-Box Family. A graphical representation of a phylogeny is shown at left with Arabidopsis Genome Initiative gene names. Schematics of identified protein structures are shown; B-box 1 is labeled as B1, B-box 2 is labeled as B2, and the CCT domain is indicated. Following the structure of each protein is the new BBX naming scheme, synonym/s for proteins, and structure groups. References: 1Koornneef et al. (1991), 2Putterill et al. (1995), 3Robson et al.
