Mutations in the CCD4 Carotenoid Cleavage Dioxygenase Gene of Yellow-Flesh Peaches

摘要

Peach trees bear either white-or yellow-flesh fruit. We found that Japanese peach cultivars have two types of mutation in a carotenoid catabolic gene, CCD4: the insertion of a retrotransposon, and a frame shift in the microsatellite sequences of the first exon. CCD4 in yellow-flesh peaches was disrupted by these mutations.
