Metabolome and transcriptome profiling in different bagging pear fruit reveals that PbKCS10 affects the occurrence of superficial scald via regulating the wax formation

•Wax content was negatively correlated with the incidence of superficial scald.•Wax components of Lupeol, lup-20(29)-en-3-one were significantly higher in the fruit bagged with non-woven fabric.•Overexpression of PbKCS10 increased the wax concentration in ‘Chili’ pear fruit.
