Segments of Adh gene in azuki bean (variety KS 5), covering an interval between partial intron 3 and intron 9, were amplified and sequenced with two pairs of primers. The result has proven the viability of using conserved sequences in a completely sequenced gene of one species to clone same gene in another species. In the comparison between Adh genes of azuki bean and pea, high sequence similarity (about 80%) in exon and long length difference (up to 116 bp) in intron were found. Besides, the edge regions of Adh introns with GT/AG counterparts and more conserved sequences than central regions was observed in both species.
