Additional file 8. Relationship between carotenoid concentration and VvCCD1 expression levels in grapevine leaves. None of the major carotenoids in the leaves of the grapevine population (measured via HPLC) showed significant correlation with VvCCD1 expression. The concentration of β-carotene (A), lutein (B), violaxanthin (C), neoxanthin (D), antheraxanthin (E) and zeaxanthin (F) found in wild-type (), silenced () and overexpression () lines is shown.
