“Yellow Jimba”: Suppression of Carotenoid Cleavage Dioxygenase (CmCCD4a) Expression Turns White Chrysanthemum Petals Yellow

Carotenoid cleavage dioxygenase (CmCCD4a) contributes to white color formation in chrysanthemum petals.

The white petals of chrysanthemum (Chrysanthemum morifolium Ramat.) are believed to contain a factor that inhibits the accumulation of carotenoids. To find this factor, we performed polymerase chain reaction-Select subtraction screening and obtained a clone expressed differentially in white and yellow petals. The deduced amino acid sequence of the protein (designated CmCCD4a) encoded by the clo...

Mutations in the CCD4 carotenoid cleavage dioxygenase gene of yellow-flesh peaches.

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.

Cloning and functional characterization of carotenoid cleavage dioxygenase 4 genes

Although a number of plant carotenoid cleavage dioxygenase (CCD) genes have been functionally characterized in different plant species, little is known about the biochemical role and enzymatic activities of members of the subclass 4 (CCD4). To gain insight into their biological function, CCD4 genes were isolated from apple (Malus x domestica, MdCCD4), chrysanthemum (Chrysanthemum x morifolium, ...

Inheritance of Carotenoid Differences I N the Tomato Hybrid Yellow

ELLOW varieties of tomatoes have been known since the crop was first Y in t roduced into Europe shortly after the discovery of America, and were probably to be found in Mexico before the conquest (JENKINS 1949). HALSTED et al. (1905) reported on the red x yellow hybrid, establishing the fact that the color difference was due to segregation at a single locus, a conclusion that has been confirmed...
