Summary: | Plants resist the invasion and establishment of pathogens through the existence of structural barriers and biochemical response mechanisms. In this regard, long non-coding RNAs (lncRNAs) have been found to play a role in various plant growth and developmental processes, as well as plant disease resistance. This study used high-throughput sequencing and bioinformatics to identify lncRNAs in kiwifruit and predict their function based on their inferred target genes. A total of 591 differentially expressed lncRNAs and 1819 mRNAs were identified in kiwifruit samples infected with P. expansum for 24 h. GO enrichment analysis indicated that the highest number of differentially expressed genes (DEGs) fell into the biological processes category of the three major ontology categories. KEGG pathway analysis indicated that most DEGs were annotated in the Plant-pathogen interaction and Plant hormone signal transduction pathways. LncRNAs in kiwifruit may be involved in the response to pathogen infections through salicylic acid (SA), gibberellin (GA), and abscisic acid (ABA) pathways. In this regard, genes, such as PP2C, GA20ox, and A-ARR, exhibited varying degrees of differential expression in kiwifruit in response to P. expansum infection. Our results provide insight into the molecular response of kiwifruit to invasion by P. expansum and provide a theoretical foundation for understanding and improving disease resistance.
