Fe2+ protects postharvest pitaya (Hylocereus undulatus britt) from Aspergillus. flavus infection by directly binding its genomic DNA

ABSTRACT: Highlights • Light was shield on Fe2+ application as antifungal agent on pitaya postharvest.• Fe2+ prevents A. flavus infection by directly binding to A. flavus DNA.• This research will promote the research on the mechanism of fungal death.• A new strategy was provided to combat fungal infection in fruit postharvest industry. Aspergillus flavus (A. flavus) is a postharvest fungus, causing pitaya fruit decay and limiting pitaya value and shelf life. However, safer and more efficient methods for preventing A. flavus contamination for pitaya fruit remain to be investigated. In this study, we successfully proved exogenous Fe2+ could inhibit A. flavus colonization in pitaya fruit and extend pitaya’s shelf life after harvest. Moreover, gel electrophoresis, CD analysis and Raman spectrum tests re
