DNA Sequence Alignment in the BBS1-3 Region of the AG Intron in 17 Brassicaceae Species.

Conserved nucleotides are in bold, and the asterisk marks the most conserved positions. BBS1, BBS2, and BBS3 are shaded. The CCAAT box and the conserved TTCATTtACc motif are underlined twice. Putative WUS and LFY binding sites are underlined with dotted and solid lines, respectively. The number at the end of each sequence indicates the position of the first nucleotide in BBS2 (indicated by an arrow) relative to the 5′ end of the AG intron (44 bp downstream of the 5′ HindIII site shown in Figure 6).
