- Abstract
UV-B is an important light condition for inducing anthocyanin synthesis in plants. Plants have corresponding photoreceptors such as UV RESISTANCE LOCUS8 (UVR8) and transduce light signals to the nucleus, which regulate the expression of structural and regulatory genes for anthocyanin synthesis through members such as ELONGATED HYPOCOTYL 5 (HY5), thereby increasing or decreasing anthocyanin accumulation. At the same time, excessive UV-B irradiation (artificial light experiments or extreme environmental conditions) is a light stress for plants, which can damage plants and cause DNA damage or even cell death and other adverse effects. In addition, the effect of UV-B on anthocyanin accumulation in plants is usually combined with other abiotic factors, including other wavelengths of light, water deficit conditions, high or low temperatures, and heavy metal ions, all of which cause plants to change their anthocyanin accumulation in time to adapt to variable survival conditions. The review aims to bring together our understanding of the interactions between UV-B and anthocyanins, which can help further the development of the anthocyanin industry. This review focuses on three aspects of the interactions between UV-B and anthocyanin in plants: (1) the light signal transduction pathway of UV-B and its regulation of anthocyanin biosynthesis; (2) the effects of UV-B and other abiotic factors on anthocyanin synthesis; and (3) the protection of anthocyanins against UV-B radiation damage. This laid a foundation for people to use UV-B to interfere with plant production of more anthocyanins.
