Grapevine (Vitis vinifera L.) is a species well known for its adaptation to radiation. However,
photomorphogenic factors related to UV-B responses have not been molecularly …

The aim of this research was to determine the effect of development and UV‐B on flavonols
and the regulation of gene activity in V itis vinifera L. var. S auvignon blanc grapes …

Background Ultraviolet (UV) radiation modulates secondary metabolism in the skin of Vitis
vinifera L. berries, which affects the final composition of both grapes and wines. The …

UV-B radiation and water deficit may trigger flavonol and anthocyanin biosynthesis in plant
tissues. In addition, previous research has showed strong qualitative effects on grape berry …

Flavonols are important ultraviolet light protectants in many plants and contribute
substantially to the quality and health-promoting effects of fruits and derived plant products …

Flavonols constitute a group of flavonoids with important photoprotective roles in plants. In
addition, flavonol content and composition greatly influences fruit quality. We previously …

Abstract Background Ultraviolet-B radiation (UV-B, 280-315 nm) is a natural component of
sunlight, which has numerous regulatory effects on plant physiology. The nature of the …

Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that
regulates growth and development in plants. Two dose-dependent UV-B response …

Abstract Anthocyanins, flavan-3-ols, and flavonols are the three major classes of flavonoid
compounds found in grape berry tissues. Several viticultural practices increase flavonoid …

Modulation of flavonoid biosynthesis in grape berries has always aroused great attention
among researchers. However, little study has been made on the shikimate pathway that …
