Thermal response KcRCB protein, coding gene thereof and application of thermal response KcRCB protein in enhancing high temperature stress resistance of plants

The invention belongs to the technical field of molecular biology breeding, and particularly relates to a thermal response KcRCB protein, a coding gene thereof and application of the thermal response KcRCB protein in enhancing high temperature stress resistance of plants. The amino acid sequence of the KcRCB protein is as shown in SEQ ID NO. 2, and the nucleotide sequence of the coding gene of the KcRCB protein is as shown in SEQ ID NO. 1. The thermal response KcRCB gene and the encoding protein thereof provided by the invention are related to the high temperature resistance of the desmodium aquilinum, and a transgenic plant with the overexpressed KcRCB gene has enhanced tolerance to high temperature stress, and can improve and enhance the response capability of the plant to high temperature stress and oxidative stress damage; the method is beneficial to stabilizing or improving the yield and quality of plants in a high-temperature frequently-occurring environment, and in addition, the method has great value
