Regulation and Improvement of Carotenoid Metabolism in Tomato

Carotenoids are essential pigments for human and plant life, but only plants can produce them. Seven hundred fifty carotenoids improve the lives of different organisms. The tomato is used as a model to get complete information on the biosynthesis of carotenoids. Different horticultural crops are used to learn about biochemical and genetic pathways. Some genes and enzymes play a significant role in regulating carotenoids, like SIPSY1 and DXS. Similarly, some pathways, like the MEP pathway, contribute a lot to the biosynthesis of carotenoids in tomatoes. This study presents a thorough overview of carotenoid biosynthesis and emphasizes new developments in genetic pathways that improve tomato carotenoid production, accumulation, and regulation.
