WebFeb 12, 2024 · Apples (Malus domestica) are rich in flavonols, and 5-aminolevulinic acid (ALA) plays an important role in the regulation of plant flavonoid metabolism. To date, the underlying mechanism of ALA promoting flavonol accumulation is unclear. Flavonol synthase (FLS) is a key enzyme in flavonol bio … Flavonol synthase (FLS) (EC-number 1.14.11.23), the enzyme that catalyses the conversion of flavonols into dihydroflavonols, is part of the flavonoid biosynthesis pathway. In Arabidopsis thaliana, this activity is thought to be encoded by several loci. In addition to the FLAVONOL SYNTHASE1 (FLS1) locus that has … See more Since the (almost) complete genome sequence of A. thaliana has been published (TASP, 2000), five genes (FLS2, At5g63580; … See more The expression of flavonoid biosynthesis enzyme genes is mainly regulated by the activity of transcription factors of R2R3-MYB, BHLH and BZIP type (overview in Quattrocchio et al. … See more Accumulation of flavonols in the mutant seedlings was analysed in a targeted metabolomic approach applying HPTLC (Fig. 4a, b). Phenylpropanoid compounds were extracted from wildtype, fls mutants and from a chalcone … See more To examine the function of FLS1–FLS6 in planta, we isolated A. thaliana plants carrying mutant alleles of these genes by reverse genetics. For FLS2–6, mutant lines with T-DNA … See more

WebBesides, shoot tissues of FLS1-OX plants exhibited lower flavonol levels than those of the wild-type. However, growth performance and abiotic stress tolerance of FLS1-OX, fls1-3, and wild-type plants were not significantly different. Taken together, FLS1 can be manipulated (i.e., silenced or overexpressed) to redirect the flavonoid biosynthetic ... WebJan 5, 2024 · Overexpression of FLS1 (FLS1-OX) not only altered seed coat color (resulting in a light brown color), but also affected flavonoid accumulation.
