Application of os07g0503900 protein in regulating plant resistance to weeds

Abstract

The invention discloses the application of Os07g0503900 protein in regulating the resistance of plants to weeds. The invention provides applications of Os07g0503900 protein or related biological materials in any of the following: regulating plant allelopathy; regulating plant resistance to weeds; regulating tricin-5-O-glucoside content in plants; Glycosylation generates tricin-5-O-glucoside; as or prepares glycosyltransferase; inhibits weed growth. Experiments show that Os07g0503900 can catalyze the glycosylation of tricin to generate tricin‑5‑O‑glucopyranoside, and tricin‑5‑O‑glucopyranoside can regulate plant allelopathy and inhibit the growth of weeds. It can be seen that Os07g0503900 has important application value in regulating the allelopathy of plants. The invention has important guiding significance for cultivating rice varieties with high allelopathic ability and regulating the biosynthesis of tricin-5-O-glucoside.

Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to the application of Os07g0503900 protein in regulating the resistance of plants to weeds. Background technique

[0002] Flavonoids are a class of natural metabolites that are widely distributed in plants and contain a C6-C3-C6 basic skeleton. The main natural flavonoids can be divided into flavonoids, flavonols, and dihydroflavonoids according to the degree of oxidation of the central three-carbon chain, whether it is cyclic or not, and the position of B-ring connection (2- or 3-position). Classes, dihydroflavonols, anthocyanins, isoflavones, etc. Most flavonoids are combined with sugar to form glycosides in plants, and some of them exist in free state (in the form of aglycone). Flavonoids have strong anti-inflammatory and anticancer effects, and have great application prospects in the treatment of cardiovascular disease, coronary heart disease, tumors and other diseases.
