Neighbor-joining tree of authentic Revolver cDNAs and Revolver -like Triticeae ESTs. Two phylogeneric trees were constructed on the exon 1 region (A), and on the exon 2 and exon 3 regions (B), respectively. Revolver-like Triticeae ESTs were diverged into at least 12 types with regardless to species on the basis of mutations in the exon 1 region. On the other hand, the phylogeneric tree on the exon 2 and exon 3 regions showed three major clusters according to wheat, rye and barley species.
