Natural variation in flavonol accumulation in Arabidopsis is determined by the flavonol glucosyltransferase BGLU6 [PDF]

Journal of Experimental Botany, 2015
Flavonols are colourless secondary metabolites, primarily regarded as UV-protection pigments that are deposited in plants in their glycosylated forms. The glycosylation of flavonols is mainly catalysed by UDP-sugar-dependent glycosyltransferases (UGTs).
