专利号:US-2025257331-A1 优先权日:2024-02-09 标题 :FLAVONOID GLYCOSIDE GLYCOSYLTRANSFERASE LbUGT71BX1 IN LAPORTEA BULBIFERA AS WELL AS THE CODING GENE AND THE USE THEREOF 发明人:WU LAN; XIANG LI; GAO RANRAN; CHEN SHILIN; SHI YUHUA; YIN QINGGANG; WANG MENGYUE; CHU YANG; WANG WENTING 权利人:INST CHINESE MATERIA MEDICA CHINA ACADEMY OF CMS 摘要:The invention discloses a flavonoid glycoside glycosyltransferase LbUGT71BX1 in laportea bulbifera as well as the coding gene and the use thereof. The amino acid sequence of the flavonoid glycoside glycosyltransferase LbUGT71BX1 is shown as SEQ ID NO: 2. The nucleotide sequence of the coding gene of the flavonoid glycoside glycosyltransferase LbUGT71BX1 is shown as SEQ ID NO: 1. According to the invention, on the basis of relevant results of the second-generation transcriptome and the third-generation full-length transcriptome sequencing of the laportea bulbifera , the last-step key enzyme LbUGT71BX1 for the synthesis of the flavonoid glycoside in the laportea bulbifera is screened and identified by using a reverse genetics method, filling the terminal blank of the biosynthesis pathway of the flavonoid glycoside in the laportea bulbifera.
专利号:US-2007232495-A1 优先权日:2006-03-24 标题:Compositions and methods to add value to plant products, increasing the commercial quality, resistance to external factors and polyphenol content thereof 发明人:NAPPA ALVARO O; LORENZINI FELIPE C; SANHUEZA ANDRES L 权利人:NAPPA ALVARO O; LORENZINI FELIPE C; SANHUEZA ANDRES L 摘要:The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and/or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and/or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and/or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and/or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and/or propagating material treated with the compositions described in the present document.
