    摘要： The present invention discloses the use of a flavonoid glycoside and glycosyltransferase gene thereof in regulating plant resistance to weeds. The present invention provides the use of tricin-5-O-glucopyranoside in any one of the following: regulating plant allelopathy; regulating plant resistance to weeds; inhibiting the growth of weeds, and the use of Os07g0503900 protein or related biological materials thereof in any one of the following: regulating plant allelopathy; regulating plant resistance to weeds; regulating the content of tricin-5-O-glucopyranoside in plants; catalyzing the glycosylation of tricin to generate tricin-5-O-glucopyranoside; act as or preparing glycosylation transferase; inhibiting the growth of weeds. The present invention is of great significance for developing environment-friendly green pesticides, cultivating rice varieties with high allelopathy and regulating the biosynthesis of tricin-5-O-glucopyranoside, and provides theoretical guidance for the control of weeds in paddy fields.

    摘要： Disclosed are methods of using Simazine for controlling, reducing formation of flowers and seedheads of, and suppressing growth of annual bluegrass (Poa annua) in a turf comprising a cool-season turfgrass species. The methods comprise applying an effective dosage of Simazine to the turf. Also disclosed is a method of enhancing color and quality of a cool-season turfgrass species as a result of Penoxsulam treatment applied to a turf comprising the cool-season turfgrass species. The method comprises applying an effective dosage of Simazine to the turf. Further disclosed is a method of selectively controlling seashore Paspalum (Paspalum vaginatum) in a turf comprising bermudagrass, the method comprising applying an effective dosage of Simazine to the turf.

    摘要： The present invention relates to the use of a protoporphyrinogen oxidase. A method for controlling weeds comprises applying a herbicide containing an effective dose of a PPO inhibitor to a field in which at least one transgenic plant is present, wherein the transgenic plant comprises, in the genome thereof, a polynucleotide sequence encoding protoporphyrinogen oxidase, and the transgenic plant has reduced plant damage and/or has an increased plant yield compared with other plants that do not have a polynucleotide sequence encoding protoporphyrinogen oxidase. The protoporphyrinogen oxidase PPO1-PPO14 of the present invention has a high tolerance to a PPO inhibitor herbicide. In addition, the plants containing the polynucleotide sequence encoding protoporphyrinogen oxidase have a strong tolerance to the PPO-inhibitor herbicide, and show high-resistance tolerance to almost all of 4-fold field concentration of oxyfluorfen, saflufenacil and flumioxazin and 2-fold field concentration of sulfentrazone. Therefore, the protoporphyrinogen oxidase has broad application prospects in plants.
