AI Technical Summary

Technical Problem

Current technologies for controlling soybean rust mainly rely on chemical agents, resulting in high production costs and significant environmental risks. Furthermore, the scarcity of resistance gene resources limits the progress of disease-resistant breeding.

Method used

Develop plant immune-inducing protein PpCAE101. By spraying or expressing this protein or its recombinant protein on the surface of plant leaves, the plant immune system is activated, and resistance to soybean rust fungus, Phytophthora infestans, Phytophthora capsici, and Fusarium graminearum is improved.

Benefits of technology

It significantly improves the disease resistance of soybeans, potatoes, tomatoes and wheat, with low application concentration, rapid effect and long duration of action, providing a green and sustainable control approach.

Abstract

The application belongs to the technical field of biology, and discloses a plant immune elicitor protein PpCAE101 and application thereof. The amino acid sequence of the protein is shown as SEQ ID NO:2, the protein can induce plant resistance, and can be applied to the field of plant disease prevention and treatment as a plant immune activator. The protein can be used to treat plants to improve the disease resistance of the plants to soybean rust fungi, and the required concentration is low, the effect is quick, and the effect time is long. The protein can activate the immune system of the plants, and provides a new way to improve the plant resistance, and thus has a wide application prospect in agricultural production.
