摘 要：In pears,blue mold decay caused by Penicillium expansum,is a destructive postharvest disease around the world,which leads to stasis of the pear industry and creates huge economic *** previous research work proved that *** mainly secretes cell wall degrading enzymes（CWDEs） to infect *** further understand the molecular basis of *** infection and disease progression,in the present study we have tried to investigate the transcriptome of pears infected with *** differentially expressed genes（DEGs） identified from the RNA-seq results were clustered into 2 upward trends and 6 downward trends according to their gene expression *** of Gene ontology（GO） terms in downward and upward trend profiles evidenced that the enriched GO terms（included metabolic processes for L-phenylalanine,aromatic amino acid family and ethylene,etc.）,found in upward trend profiles were more relevant to pear ***,the Kyoto Encyclopedia of Genes and Genomes（KEGG） results revealed that pears can produce a complex defense response against *** ***,*** produced CWDEs to establish infection,which triggers relevant transduction pathways in *** pathways led to further activation of the secondary regulatory ***,some metabolites were synthesised to defense against *** general,the information obtained in this study will be supportive to develop new strategies to control fungal diseases.
