Flavonoid biosynthesis arabidopsis. Oct 18, 2019 · Chalcone synthase (CHS), chalcone isomerase (CHI), flavonol 3-hydroxylase (F3H) and flavonol 3′-hydroxylase (F3′H) are together involved in biosynthesis of common precursors for the flavonoids in Arabidopsis. Here, we report an analysis of the diverse and specific flavonoids that accumulate during … Feb 12, 2013 · Together, these results provide a molecular model consistent with the specific and highly regulated expression of TT8. The AtMYB12 gene from Arabidopsis thaliana has been shown to regulate the expression of key enzyme genes involved in flavonoid biosynthesis, leading to the increased accumulation of flavonoids. Sep 28, 2012 · Flavonoids are synthesized through the phenylpropanoid pathway, transforming phenylalanine into 4-coumaroyl-CoA, which finally enters the flavonoid biosynthesis pathway (Figure 2). The biosynthesis of flavonoids has long been the focus of intense research in plant biology. Oct 26, 1999 · Here we describe the use of biochemical genetic methods to provide evidence for specific protein–protein interactions among four enzymes of flavonoid biosynthesis in Arabidopsis. This review describes the state-of-art of flavonoid biosynthetic pathway in Arabidopsis regarding both structural and genetic diversity, focusing on the genes encoding enzymes for the biosynthetic reactions and vacuole translocation. Abstract Flavonoids are an important class of secondary metabolites widely found in plants, contributing to plant growth and development and having prominent applications in food and medicine. Polyphenolic compounds represent one of the most numerous and widely distributed groups of substances in the plant kingdom (Tohge et al. Jun 21, 2017 · Here we provide an inventory of current knowledge of pathways of flavonoid biosynthesis in both the model plant Arabidopsis thaliana and a range of crop species, including tomato, maize, rice, and bean. Flavonoids are major secondary metabolites derived from the plant phenylpropanoid pathway that play important roles in plant development and also have benefits for human health. Various stages of flavonoid biosynthesis are subject to complex regulation by three groups of transcription regulators—MYC-like bHLH, R2R3-MYB and In plants, transcriptional regulation is the most important tool for modulating flavonoid biosynthesis. The in vivo relevance of the additional activities attributed to these enzymes, however, has remained obscure. Functional characterization of genes involved in the flavonoid metabolism and its regulation requires in-depth analysis of flavonoid structure and composition of seed from the model plant Arabidopsis thaliana. The first enzyme specific for the flavonoid pathway, chalcone synthase, produces chalcone scaffolds from which all flavonoids derive. These compounds possess diverse functions in plants including Jan 16, 2025 · Flavonoids are a large group of secondary metabolites, which are responsible for pigmentation, signaling, protection from unfavorable environmental conditions, and other important functions, as well as providing numerous benefits for human health. The coordinated activity of different flavonoid biosynthesis genes in Arabidopsis thaliana results in tissue-specific accumulation of flavonols, anthocyanins and proanthocyanidins (PAs). Jul 1, 2010 · In vitro experiments suggested that the dioxygenases involved in their biosynthesis, flavonol synthase and anthocyanidin synthase, are “multifunctional” enzymes showing distinct side activities. Nov 1, 2013 · This review describes the state-of-art of flavonoid biosynthetic pathway in Arabidopsis regarding both structural and genetic diversity, focusing on the genes encoding enzymes for the biosynthetic reactions and vacuole translocation. They shed new light into the transcriptional regulation of flavonoid biosynthesis and provide new clues and tools for further investigation in Arabidopsis and other plant species. , 2013 a).
