Development of a co-dominant, PCR-based marker for allelic selection of the pink trait in onions (Allium cepa), based on the insertion mutation in the promoter of the anthocyanidin synthase gene.

Abstract excerpt

Bulb color in onions (Allium cepa) is an important trait and is inherited in a complex manner. However, the mechanism of color inheritance is poorly understood at the molecular level. A previous study showed that pink bulb color in onions is inherited as a single recessive trait. This trait is attributable to a significantly reduced transcription of the anthocyanidin synthase (ANS) gene. In this study, we...
