Abstract
The invention discloses Ustilaginoidea virens effect protein UvScd1 and application thereof.The target gene UvScd1 is introduced into a secreting type expression vector pBE-S, a strain capable of secreting the target protein UvScd1 is obtained through bacillus subtilis, then a bacterial liquid of the strain is used for treating rice leaves, rice rhizoctonia solani and xanthomonas oryzae are inoculated, and the Ustilaginoidea virens effect protein UvScd1 is obtained. It is found that the rice treated with the bacterial liquid can enhance the resistance to rice sheath blight disease and bacterial leaf blight. Therefore, the invention provides possibility for researching and developing a bacillus subtilis biocontrol strain for preventing and treating rice sheath blight disease and bacterial leaf blight.
