Whether the calyx tube of Korla fragrant pear falls off seriously affects fruit quality. ‘Xinnonglinxiang’ is a mutant variety pear, which has high removal rate under natural conditions, and fall The mechanism behind remains unclear; thus, (PT) (YB) with different degrees abscission were used as examples areas tubes collected in early (21 April), middle (23 late (25 April) shedding stages to explore regulatory abscission. combination results physiological, cytological, transcriptomic methods indicated highest number differentially expressed genes (DEGs) shedding. GO (Gene Ontology) enrichment analysis showed that expression levels related CEL (cellulase) PG (polygalacturonase) activity functional pathways differed significantly two varieties during three periods, whereas Kyoto Encyclopedia Genes Genomes (KEGG) DEGs concentrated plant hormone signal transduction pathway all periods. for Five gene modules obtained using Weighted Gene Co-Expression Network Analysis (WGCNA), transcriptome data correlated five physiological index values. Two key highly Eth (ethylene) response then screened, 20 core identified, IRX10, IRX9, OXI1 likely hub are involved regulation YB variety. provide reliable screening candidate rate, providing theoretical basis upon fruits can be improved through genetic improvement.
