Sequence analysis of IbBT4. (A) Sequence alignment of IbBT4 and its homologs from other plant species. The conserved amino acids are indicated by a dark background. Inline graphic, BTB_POZ_BT domain; Inline graphic, ZnF_TAZ domain; Inline graphic, BACK domain. (B) Phylogenetic analysis of IbBT4 and BT proteins from other plant species. (C) Exon and intron constituents of BT4 genes. The exons are represented by boxes; the introns, by lines.
