Potential epigenetic regulation of RNA 5’-terminal NAD decapping associated with cellular energy status of postharvest Fragaria × ananassa in response to Botrytis cinerea invasion

•Energy metabolism was associated with gray mold disease of postharvest strawberry.•PN functioned as an immune regulator linked energy status with fruit immunity.•B. cienrea applied patterns manipulating strawberry immune genes and PN metabolism.•Localization and structure of FaDXO1 were conserved in NTE and catalytic domain.•deNADing of DXO and TIR domain has epigenetic potential to regulate fruit immunity.
