Description

Technical field

[0001] The invention belongs to the field of biotechnology, and specifically relates to a strain of Aspergillus aculeatus and its application. Background technique

[0002] Aspergillus aculeatus is a kind of Aspergillus Niger, a filamentous fungus belonging to the genus Aspergillus. Aspergillus aculeatus has various biologically active metabolites, such as the antibacterial factor auleacinsA–G, the α-glucosidase inhibitor aspergillusolA, the antimicrobial factor secalonicacids D and F and so on. These compounds have antimicrobial, antifouling, antifeedant activity and phytotoxin activity. In the existing reports, the ability of such strains to induce disease resistance has not been explored in depth.

[0003] Salicylic acid is an important signal molecule in plant resistance to various diseases and response to pathogenic attacks, and it plays a key role in regulating the physiological growth of plants. It is an important inducer of plant systemic acquired resista...
