DNA Damage Inducible Protein 1 is Involved in Cold Adaption of Harvested Cucumber Fruit.

ABSTRACT: Chilling stress can cause cellular DNA damage, affecting the faithful transmission of genetic information. Cold acclimation enhances chilling tolerance, but it is not clear that the process of cold adaption involves DNA damage responses, as cold acclimation does not form real chilling stress. Here we showed with cucumber fruit that pre-storage cold acclimation (PsCA) reduces chilling injury and upregulates DNA damage inducible protein1 (CsDDI1), suggesting that the chilling tolerance induced by cold acclimation involves CsDDI1 transcription. Application of nitric oxide (NO), abscisic acid (ABA) or H₂O₂ biosynthesis inhibitor before PsCA treatment downregulates CsDDI1 and aggravates chilling injury, while H₂O₂ generation inhib
