Expression of four genes of the anthocyanin pathway coding for phenylalanine ammonialyase, chalcone synthase, flavanone-3-hydroxylase, and the UDP-glucose: flavonoid-3-O-glucosyltransferase (UFGT), was analyzed by RT-PCR at three developmental stages from before the onset of ripening to full maturity.

2017年2月7日 · We found that UDP-glucose: flavonoid 3-O-glucosyltransferase (UFGT) gene showed differential expression pattern. The UFGT enzyme activities in RF had a significantly higher than that of WF and lower in the initial stage and increased when the red appeared in the petals, which is identical to the accumulation of anthocyanins.

2022年7月27日 · Among these factors, the UDP-glucose: flavonoid 3- O -glucosyltransferase (UFGT s) have a major role in the development and production of flowers and fruits colors. The UFGT enzymes are critical for upholding anthocyanin synthesis, acylation, and glucosylation in horticulture plants.

本研究从大卫紫菜中克隆了参与花青素生物合成的关键基因 VdUFGT，并使用农杆菌介导的方法进行基因过表达。 值得注意的是，vgt3 转基因细胞系的花青素含量增加了 4.4 倍，在固体培养基中达到 286.9 μg/g （FW），同时黄酮类化合物和原花青素水平升高。 转录组学和代谢组学的综合分析表明，VdUFGT 显著促进花青素生物合成相关基因的表达，导致包括花青素在内的各种黄酮类化合物的积累增强。 建立了一个小型植物细胞工厂，在短短 12 天内实现了 4.11 mg/g （DW） 的 …

2025年3月10日 · UFGT is the final gene in the anthocyanin biosynthesis pathway (Chen et al. 2015). The UFGT is the primary regulatory factor for anthocyanin synthesis, promoting the transfer of glucose to the C-3 hydroxyl group of anthocyanidins, resulting in the colorful pigments referred to as anthocyanin 3-O-glucosides (Zhao et al. 2012a, b).

UDP-glucose: flavonoid 3-O-glycosyltransferase (UFGT, EC. 2.4.1.91) stabilizes anthocyanidin by attaching sugar moieties to the anthocyanin aglycone. In this study, the function of an UFGT gene involved in the biosynthesis of anthocyanin was verified through heterologous expression and virus-induced gene silencing assays.

UDP 葡萄糖：类黄酮-3-O-葡萄糖基转移酶 (UFGT) 基因在果实着色过程中调节荔枝 (Litchi chinesis Sonn.) 中的花青素生物合成。 Molecular Biology Reports ( IF 2.6) Pub Date : 2012-03-27, DOI: 10.1007/s11033-011-1303-3

摘要 类黄酮糖基转移酶(ufgt)可以把不稳定的花色素催化成花色素苷,是花色素苷合成过程中的最后一个酶。在一定范围内,类黄酮糖基转移酶活性与花色素苷的合成呈现正相关,抑制ufgt酶活性比抑制其他酶更能影响花色素苷的合成。

ufgt 酶对于维持园艺植物中的花青素合成、酰化和葡糖基化至关重要。本文总结了 ufgt 编码基因在色素形成中的作用，特别是花青素的形成。此外，这篇评论文章强调了ufgt的联合作用s 和其他下游基因在最后一步稳定花青素。

In enzymology, a flavonol 3-O-glucosyltransferase (EC 2.4.1.91) is an enzyme that catalyzes the chemical reaction. Thus, the two substrates of this enzyme are UDP-glucose and flavonol, whereas its two products are UDP and flavonol 3-O-beta-D-glucoside.
