摘要：

Marigold ( Tagetes erecta ) serves as both an ornamental and economically significant species, owing to its diverse floral coloration and exceptionally high petal carotenoid content. Carotenoid cleavage dioxygenase (CCD), as the key enzymatic component, mediates the carotenoid degradation process. In this study, we cloned and functionally characterized a CCD4 gene to elucidate its regulatory function in petal color and carotenoid biosynthesis. Our findings revealed that in the deep-orange marigold cultivar ‘Lady’, the expression of the TeCCD4...
