Long non-coding RNAs (lncRNAs), known to participate in various physiological processes including plant defense against diseases, have an undefined role in kiwifruit's resistance.<h4>Results</h4>Our study aimed to identify lncRNAs induced by B. cinerea infection in 'Hongyang' kiwifruit at 0 to 3 days post-inoculation (dpi) through high-throughput sequencing. The differential expression analysis identified 126 differentially expressed lncRNAs (DELs). Subsequent GO and KEGG analyses indicated that these lncRNAs' target genes were predominantly associated with plant-pathogen interactions, carbohydrate metabolism including starch and suBMC plant biologyTranscriptomic analysis reveals long non-coding RNA involved in the key metabolic pathway in response to Botrytis cinerea in kiwifruit.PMC1199842932001351CSTB2023NSCQ-MSX0066Yang JLi ZJue DSui YMa YZhong HWang XZeng TfalseTranscriptomic analysis reveals long non-coding RNA involved in the key metabolic pathway in response to Botrytis cinerea in kiwifruit.<h4>Background</h4>Understanding the molecular mechanisms that confer kiwifruit resistance to Botrytis cinerea is essential for developing resistant cultivars.
