“…When plants are subjected to cold stress, the positive regulators ICE1 (inducers of CBF expression 1), CAMTA3 (calmodulin-binding transcription activator 3) and BZR1/BES1 (brassinazole-resistant 1) and negative regulators MYB15, PIFs (phytochrome-interacting factors) and EIN3 (ethylene-insensitive 3) modulate CBF gene expression (Liu et al 2019b ). Then, the CBF proteins bind to the C-repeat of downstream cold-responsive ( COR ) genes (Song et al 2021 ; Fig. 2 ).…”

“…In contrast, 4 °C storage induces the occurrence of CI. In another study the authors focused on the study of membrane lipid metabolomics in peach fruit in response to exogenous application of γ-aminobutyric acid (GABA) (Song et al 2023). The treatment was able to improve peach tolerance to low temperature by inhibiting phospholipid degradation and thus reducing the accumulation of phosphatidic acid and maintaining higher levels of phosphatidylcholine and phosphatidylethanolamine.…”

Storage or transportation temperature is very important for preserving the quality of fruit. However, low temperature in sensitive fruit such as peach can induce loss of quality. Fruit exposed to a specific range of temperatures and for a longer period can show chilling injury (CI) symptoms. The susceptibility to CI at low temperature varies among cultivars and genetic backgrounds. Along with agronomic management, appropriate postharvest management can limit quality losses. The importance of correct temperature management during postharvest handling has been widely demonstrated. Nowadays, due to long-distance markets and complex logistics that require multiple actors, the management of storage/transportation conditions is crucial for the quality of products reaching the consumer.Peach fruit exposed to low temperatures activate a suite of physiological, metabolomic, and molecular changes that attempt to counteract the negative effects of chilling stress. In this review an overview of the factors involved, and plant responses is presented and critically discussed. Physiological disorders associated with CI generally only appear after the storage/transportation, hence early detection methods are needed to monitor quality and detect internal changes which will lead to CI development. CI detection tools are assessed: they need to be easy to use, and preferably non-destructive to avoid loss of products. Graphical Abstract
