ABSTRACT = {Sweet potato is a multifunctional root crop and a source of food with
many essential nutrients and bioactive compounds. Variations in the flesh color
of the diverse sweet potato varieties are attributed to the different phytochemicals
and natural pigments they produce. Among them, carotenoids and anthocyanins
are the main pigments known for their antioxidant properties which provide a host
of health benefits, hence, regarded as a major component of the human diet. In
this review, we provide an overview of the major pigments in sweet potato with
much emphasis on their biosynthesis, functions, and regulatory control. Moreover, current findings on the molecular mechanisms underlying the biosynthesis
and accumulation of carotenoids and anthocyanins in sweet potato are discussed.
Insights into the composition, biosynthesis, and regulatory control of these major
pigments will further advance the biofortification of sweet potato and provide a
reference for breeding carotenoid- and anthocyanin-rich varieties.},
