Application of activator protein prepared from Alternaria tenuissima by microbial fermentation to pesticide preparation

Abstract

The invention discloses an application of an activator protein prepared from Alternaria tenuissima by microbial fermentation to a pesticide preparation. The activator protein from Alternaria tenuissima which is prepared from Alternaria tenuissima by fermentation and special extraction processes is a single and stable protein with biological activities. The protein can be prepared with glucosamine oligosaccharides and related protein protectants into wettable powder, the protein can be combined with a receptor protein on a plant cell membrane, in order to induce increases of a series of related enzymatic activity and gene expression quantity in the plant, stimulate a series of metabolism regulation in the plant, promote growth of roots, stems and leaves of the plant, increase chlorophyll content, and increase crop yield. The wettable powder prepared by the protein from Alternaria tenuissima completely accords with each national index, and has the effects for preventing and controlling plant virus diseases, greatly improving physiological functions of plants, enhancing disease resistance of plants, and increasing crop output to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation production, and relates to the application of Alternaria ultrafines activator protein obtained through microbial fermentation in pesticide preparations. Background technique [0002] Alternaria ultrafines can produce a plant activating protein that induces systemic resistance in a variety of plants. The crude extract of this protein has ideal growth-promoting and inducing effects on cucumber, rice, tomato, tobacco, and cabbage. It is environmentally safe, does not cause plant resistance, and is a new type of biopesticide with broad development prospects. [0003] Alternaria tennatus activating protein is a single, stable protein with biological activity extracted by fermentation of Alternaria tenurica. The protein is composed of 207 amino acids, its theoretical molecular weight (2005 new atomic weight standard) MW=22590, and its isoelectric point is 4.43. It is easily soluble in wat...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no domestic report on the preparation of Alternaria ultrafines activating protein as the original drug into pesticide preparations, which are widely used in sterilization and enhance the plant's own resistance to remove plant diseases and increase crop yield.
