Abstract Cold-sensitive fruit stored at low temperatures after harvest is vulnerable to fruit chilling injury, and low-temperature conditioning (LTC) treatment has notable effect in alleviating chilling injury of cold-sensitive fruit such as peach (Prunus persica), but slight fruit softening occurs in the initial stage of storage. In this study, weighted gene co-expression network analysis (WGCNA) was used to identify gene modules that were highly correlated with chilling injury and firmness phenotypes. The analysis revealed that WRKY transcription factor PpWRKY43 and P. persica auxin response factor 1 (PpARF1) might be involved in postharvest chilling injury regulation by regulating cold-regulated 413 inner membrane protein 2 (PpCOR413-2) and the lipoxygenase 5 (PpLOX5), and NAC transcription factor PpNAC5 might be involved in postharvest softness of peach fruit by regulating P. persica pectate lyase 2 (PpePL2). The results of this study provides basic data for postharvest preservation and reduction of peach fruit injury.

Key words： Peach Postharvest Chilling injury Weighted gene co-expression network analysis (WGCNA) Firmness
