Abstract

Abstract:

To explore the inhibition mechanism of dark septate endophytes fungus A024 Phialocephala bamuru against Rhizoctonia solani Kühn, the non-targeted metabonomics of fungus A024 induced by R. solani were analyzed by LC-MS system. The results showed that the metabolites of A024 strain included 9 categories and 27 classes, and 52 differential metabolites were screened out. Compared with the control group, 31 of them were up-regulated and 21 of them were down-regulated after induction, among which, flavonoids, L-malic acid, guanosine monophosphate and nicotinic acid were significantly up-regulated. Arachidonic acid metabolism, biosynthesis of histidine and purine alkaloids, biosynthesis of plant secondary metabolites, biosynthesis of terpenoids and polyketide alkaloids were significantly enriched in the analysis of KEGG enrichment. Different metabolites and their enriched metabolic pathways were screened in the study, which laid a foundation for further research on the mechanism of their inhibition on R. solani.

Key words: dark septate endophytes, Rhizoctonia solani Kühn, metabonomics, differential metabolites, KEGG enrichment
