Identification of a 982-kb deletion including the DFR-A gene responsible for the lack of anthocyanin in onion (Allium Cepa L.) and development of a codominant marker for detection of the deleted DFR-A allele
{{output}}
The DFR-A gene, which encodes dihydroflavonol 4-reductase, an enzyme involved in the anthocyanin biosynthesis pathway, was previously identified as the causal gene responsible for yellow bulb color in onion (Allium cepa L.). Among the various DFR-A alleles, no... ...
