Transcriptome Analysis Reveals the Changes of Multiple Genes Involved in Disease Resistance of Postharvest “Huangguan” Pears Treated With Lysobacter enzymogenes MB01

“Huangguan” pears during storage are easily infected by various diseases, which resulted in substantial economic losses due to the decline in production and quality. Being a biocontrol bacterium, Lysobacter enzymogenes MB01 ( L. enzymogenes MB01) can bring about the alterations of related defense enzymes, thereby enhancing the shelf life. The genetic changes in samples treated with L. enzymogenes MB01 were discussed by transcriptome. The outcomes indicated that compared to the control, L. enzymogenes MB01 restrained the disease index and total bacterial count and improved the defense enzyme activity. The transcriptome data uncovered the presence of 1975 differentially expressed genes (DEGs). The results of the Kyoto Encyclopedia of Genes and Genomes (KEGG) revealed that the majority of DEGs were enriched in plant hormone signal transduction, phenylpropanoid biosynthesis, plant‐pathogen interaction, flavonoid biosynthesis, and stilbenoid, diarylheptanoid, and gingerol biosynthesis. The above results suggested the treatment with L. enzymogenes MB01 induced the disease resistance of pears through regulating multiple genes, which offers a feasible method for protecting fruit against pathogen during storage.
