摘要：

A cDNA clone (DFR) encoding dihydroflavonol 4-reductase was identified from tomato hypocotyls. Nucleotide and amino acid sequence comparisons to Petumia hybrida, Antirrhinum majus and Zea mays DFR sequences confirmed that the cDNA encodes the structural DFR gene. In tomato, the DFR sequence appeared to be present as a single gene and mapped to a region on chromosome 2 near two loci affecting anthocyanin pigmentation, are and aw. DFR was expressed in both leaf and hypocotyl tissue. Sequencing data from two DFR cDNA clones indicated there are alternative polyadenylation sites on DFR.
