AI Technical Summary

Technical Problem

In existing technologies, the control of soybean Phytophthora root rot is difficult, the effective utilization period of a single disease resistance gene is short, resulting in serious damage to soybean production and a lack of long-lasting and efficient disease resistance gene resources.

Method used

By overexpressing or knocking out the soybean BSP family gene Glyma.20G130000.1, the resistance of soybean to soybean root rot was improved. The resistance was verified using transient expression technology, and the knockout effect was verified using stable transgenic technology.

Benefits of technology

This study successfully improved soybean resistance to soybean root rot caused by Phytophthora infestans. Soybean plants overexpressing the Glyma.20G130000.1 gene showed stronger resistance, while knocking out the gene resulted in reduced resistance. This study provides genetic resources and tools for disease-resistant breeding.

Abstract

The invention belongs to the technical field of gene engineering, and particularly discloses application of a soybean BSP family Glyma. 20G130000.1 gene in resistance of soybean phytophthora root rot. According to the invention, the gene Glyma. 20G130000.1 is obtained by cloning from soybean, and the gene Glyma. 20G130000.1 is efficiently expressed in a soybean plant through instantaneous transformation, so that an overexpression soybean plant is obtained. Functional identification results show that compared with a control plant, a soybean plant with the overexpressed Glyma. 20G130000.1 gene shows significantly enhanced disease resistance to phytophthora sojae. In addition, the invention also provides application of a biological material related to the gene, and a method for screening or cultivating a disease-resistant soybean plant based on the gene. Therefore, the Glyma. 20G130000.1 gene not only provides an effective tool for revealing a basic resistance mechanism of the soybean to the phytophthora root rot, but also provides a valuable gene resource for soybean disease-resistant breeding.
