Application of rice OsSAFM10 gene or protein coded by rice OsSAFM10 gene in improving resistance of rice to magnaporthe oryzae

The invention discloses application of a rice OsSAFM10 gene or a protein coded by the rice OsSAFM10 gene to improvement of rice blast resistance of rice, and relates to the technical field of rice blast prevention and control. Researches show that the protein coded by the rice gene OsSAFM10 can be used as a medicament for preventing and treating rice blast. The OsSAFM10 protein has an obvious inhibition effect on magnaporthe oryzae appressorium, when the concentration of the OsSAFM10 is 0.05 mu g/mu L, the spore germination rate of the magnaporthe oryzae is 74.66%, and when the concentration of the OsSAFM10 reaches 0.1 mu g/mu L, the spore germination rate of the magnaporthe oryzae is 61.33%. Therefore, the protein coded by the rice gene OsSAFM10 can be used for improving the resistance of rice to the rice blast bacteria. 本发明公开了水稻OsSAFM10基因或其编码的蛋白在提高水稻抗稻瘟病菌中的应用，涉及水稻稻瘟病防治技术领域。本发明经研究发现水稻基因OsSAFM10编码的蛋白质可以作为药剂用于防治稻瘟病。OsSAFM10蛋白对稻瘟病菌附着胞具有明显的抑制作用，当OsSAFM10浓度为0.05μg/μL时，稻瘟病菌孢子萌率为74.66％，当OsSAFM10浓度达到0.1μg/μL时，稻瘟病菌孢子
