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.

The present invention relates to plants, particularly crop plants, having enhanced tolerance to biotic stress, particularly enhanced tolerance to stress caused by a wide range of plant pathogens. The tolerant plants of the invention show enhanced expression of Arabidopsis S30 protein or of homologs or orthologs thereof.

A technique for inducing tolerance to environmental stress in a plant is provided. Tolerance to environmental stress in a plant is induced by applying to the plant an abscisic acid-like substance, such as abscisic acid and agonists thereof, in combination with a nitrogen-containing compound, such as amino acids and amino acid derivatives.

Compositions and methods of using exogenous antioxidant compounds and additives for Cannabis and hemp production and growth and methods for enhancing the production of secondary metabolites and alleviating stress in Cannabis and hemp plants are described.

The present application discloses a plant senescence accelerator named IDL7 mature polypeptide, and its preparation method and an application thereof. The application belongs to the field of a plant senescence accelerator, and the IDL7 mature polypeptide serves as a major functional ingredient with the following amino acid sequence: F-G-S-L-V-L-N-A-L-P-K-G-S-R-P-G-S-G-P-S-K-K-T-N. The IDL7 mature polypeptide plant senescence accelerator may promote the leaf senescence of plants without other additional adverse manifestations, thus this application has strong field operability.

The present invention relates to a method of improving growth of plants and/or improving germination of plants by applying flonicamid to said plant or plant propagation material or the locus thereof.
