Gene Details:

• Gene ID:
• Gene Symbol: FcrNAC22
• Gene Name:
• Genome:
• Species: Fortunella crassifolia

Functional Descriptions:

• Red light-induced kumquat fruit coloration is attributable to increased carotenoid metabolism regulated by FcrNAC22.
• FcrNAC22 localizes to the nucleus, and its gene expression is up-regulated as fruits change color. Results from dual luciferase, yeast one-hybrid assays and electrophoretic mobility shift assays indicate that FcrNAC22 directly binds to, and activates the promoters of three genes encoding key enzymes in the carotenoid metabolic pathway.
• FcrNAC22 overexpression in citrus and tomato fruits as well as in citrus callus enhances expression of most carotenoid biosynthetic genes, accelerates plastid conversion into chromoplasts, and promotes color change.
• Taken together, our results demonstrate that FcrNAC22 is an important transcription factor that mediates red light-induced fruit coloration via up-regulation of carotenoid metabolism.
