V. Lefebvre et al., THE CAPSANTHIN-CAPSORUBIN SYNTHASE GENE - A CANDIDATE GENE FOR THE Y-LOCUS CONTROLLING THE RED FRUIT COLOR IN PEPPER, Plant molecular biology, 36(5), 1998, pp. 785-789
The red colour of pepper fruits is determined by the y(+) dominant all
ele and the yellow colour by the y recessive allele. The capsanthin-ca
psorubin synthase (CCS) gene is activated specifically during the fina
l stages of pepper fruit ripening. RFLP and specific-PCR polymorphisms
derived from the CCS gene were analysed in a F2 progeny of a red by y
ellow-fruited cross. They cosegregated completely with fruit colour. O
ur results support the hypothesis that the yellow phenotype might resu
lt from a deletion of the CCS gene. These specific markers were integr
ated into the genetic map and will be useful for marker assisted plant
breeding.
