AI Technical Summary

Technical Problem

Existing chemical pesticides pose problems of pathogen resistance and environmental pollution in the control of bacterial plant diseases, while there is limited research on plant immune inducers in activating plant immunity.

Method used

Using Panax notoginseng saponin Ft1 as a plant immune inducer, it enhances plant resistance to bacterial diseases by upregulating the expression of key immune genes FRK1, activating plant reactive oxygen species burst, activating calcium ion influx, and promoting MAPK protein phosphorylation.

Benefits of technology

Panax notoginseng saponin Ft1 activates plant immune responses at low concentrations, enhances resistance to pathogens, and does not inhibit plant growth. It has broad-spectrum and low-pollution properties, and has broad application prospects.

Abstract

The invention discloses application of notoginsenoside Ft1 as a plant immune resistance inducer in prevention and treatment of plant bacterial diseases, and belongs to the technical field of biopesticides. It is found for the first time that notoginsenoside Ft1 can effectively activate a plant immune system, promote FRK1 immunomarker gene expression, induce active oxygen bursting and calcium ion influx, and activate MAPKs protein phosphorylation, so that the resistance of plants to bacterial diseases such as pseudomonas syringae is enhanced. Different from existing other types of notoginsenoside serving as bactericides for directly inhibiting fungi, notoginsenoside Ft1 plays a role in activating autoimmunity of plants, has no inhibition effect on plant growth under effective concentration, has the characteristics of high efficiency, safety and environmental friendliness, and can be used as a novel biopesticide for preventing and treating plant bacterial diseases.
