Three cultivars of Oncidium orchid with varied coloration, such as Oncidium Gower Ramsey (yellow), Sunkist (orange), and White Jade (white), were analyzed for carotenoid metabolites and gene expression of carotenoid-biosynthetic genes. The HPLC analysis revealed that yellow Gower Ramsey accumulates violaxanthin, 9-cis-violaxanthin and neoxanthin, orange… CONTINUE READING
