The modulation of light quality on carotenoids in maize (Zea mays L.) sprouts

ABSTRACT: Highlights • Red and blue light were associated with increased carotenoid biosynthesis.• Lutein contents increased to 6.3 and 14 folds following red and blue light exposure.• Blue light was associated with higher expression of HY5 and CHYB.• ERF021 and MYB68 were negatively associated with carotenoid biosynthesis.• Phytohormones (IAA, SL and GA) were related to carotenoid biosynthesis. The present study aimed to identify the regulatory mechanisms of red, blue, and white light on carotenoid biosynthesis in maize sprouts. Determinations of carotenoid, chlorophyll and phytohormone profiles, as well as relative gene expression, were explored. The results identified enhancement of carotenoid and chlorophyll production as well as gene expression. Most notably, the expression levels of CRY, HY5,
