Natural variation in flavonol accumulation in Arabidopsis is determined by the flavonol glucosyltransferase BGLU6
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). Although the structures of flavonol glycosides accumulating in Arabidopsis thaliana are known, many genes involved in the flavonol glycosylation...
متن کاملUDP-glucose: glucosyltransferase activity involved in the biosynthesis of flavonol triglucosides in Pisum sativum L. seedlings.
From young, light-grown seedlings of Pisum sativum L. an enzyme activity catalyzing the glucosylation of kaempferol and quercetin in the 3-position to form the 3-0-triglucoside derivative has been demonstrated. The reaction proceeds from the aglycone via the mono- and diglucoside intermediates. The triglucoside can be produced from any of the less substituted derivatives with uridine diphosphat...

متن کاملAuxin and ethylene induce flavonol accumulation through distinct transcriptional networks.
Auxin and ethylene are key regulators of plant growth and development, and thus the transcriptional networks that mediate responses to these hormones have been the subject of intense research. This study dissected the hormonal cross talk regulating the synthesis of flavonols and examined their impact on root growth and development. We analyzed the effects of auxin and an ethylene precursor on r...
متن کاملThe Arabidopsis transcription factor MYB12 is a flavonol-specific regulator of phenylpropanoid biosynthesis.
Comprehensive functional data on plant R2R3-MYB transcription factors is still scarce compared to the manifold of their occurrence. Here, we identified the Arabidopsis (Arabidopsis thaliana) R2R3-MYB transcription factor MYB12 as a flavonol-specific activator of flavonoid biosynthesis. Transient expression in Arabidopsis protoplasts revealed a high degree of functional similarity between MYB12 ...
