The present disclosure provides a microbial agent YF, including four strains: Bacillus sonorensis B-2, Bacillus paralicheniformis B-26, Bacillus sonorensis N-16, and Bacillus pumilus N-17. The four strains were all deposited in the China General Microbiological Culture Collection Center (CGMCC) on Mar. 5, 2020. The Bacillus sonorensis B-2 has a deposit accession number of CGMCC NO. 19454, the Bacillus paralicheniformis B-26 has a deposit accession number of CGMCC NO. 19449, the Bacillus sonorensis N-16 has a deposit accession number of CGMCC NO. 19448, and the Bacillus pumilus N-17 has a deposit accession number of CGMCC NO. 19450. The microbial agent provided by the present disclosure can effectively prevent stem rot of corn in saline-alkali land, improve the quality of saline-alkali land, and significantly promote the growth of corn.

The present invention belongs to the field of biotechnology, in particular to a multivalent fusion protein AB-NAC-189, method for producing the same, and uses thereof. The protein AB-NAC-189 is a fusion of a polypeptide segment AB, nascent polypeptide-associated complex (NAC), and a protein 189 corresponding to amino acids 1-189 from the N-terminal of protein HarpinEa. The fusion has the properties of a multivalent plant immune protein, thus it can effectively stimulate the hypersensitive response of tobacco leaves and has good thermal stability. While stimulating the immune response of plants, it can also improve the disease resistance of plants and promote plant growth. The AB-NAC-189 multivalent vaccine shows higher activity per unit concentration, and greater ability to promote growth of wheat and tobacco; meanwhile it can significantly promote chlorophyll synthesis in Goji berry, thereby improving the yield and quality of Goji berries.
