Alignment of the genomic nucleotide sequences of wheat F3H-A1, F3H-B1, and F3H-D1. Uppercase letters in gray boxes indicate exons: 5′ and 3′ untranslated region and introns are in lowercase letters. Putative translation initiation codon (ATG) is shown in italic and A of ATG is labeled as +1, and stop codons (TGA and TAG) are shown as underlined. Primer sequences are written in bold with the primer name and arrow (right arrow: sense primer; left arrow: antisense primer).
