Summary: This study demonstrates that hydrogen sulfide treatment can reduce chilling injury in cucumber fruits, delaying the increase in electrolyte leakage and malondialdehyde content. The H2S-treated fruits exhibit higher antioxidant capacity and enzyme activities involved in energy metabolism, as well as lower levels of reactive oxygen species. Additionally, H2S treatment enhances the activities of key enzymes involved in proline metabolism, promoting proline accumulation.

Summary: Chilling injury (CI) of tomato fruit can deteriorate fruit quality and shorten shelf life. This study investigated the effect of Sly-miR167a on postharvest cold tolerance of tomato fruit. Results showed that overexpression of Sly-miR167a reduced electrolyte leakage, hydrogen peroxide content, malondialdehyde content, and CI index during low temperature storage. The overexpressed fruit also accumulated higher levels of Ascorbic acid, proline, lycopene, phenolics, and maintained higher activities of antioxidant enzymes. At low temperatures, the overexpressed fruit had better quality and exhibited lower expression levels of ARF6a, higher ethylene production, and higher expression levels of CBF1. Overexpression of Sly-miR167a delayed the appearance of CI symptoms and improved the chilling tolerance of postharvest tomato fruit.

Summary: Given the widespread use of cold chain, it is crucial to develop postharvest technologies for reducing chilling injury in fruits and vegetables. Maintaining intracellular adenosine triphosphate (iATP) has been found to be beneficial in inhibiting chilling injury. Extracellular ATP (eATP) acts as a damage-associated signal molecule and plays a significant role in chilling injury of postharvest fruits and vegetables through its receptor and subsequent signal transduction under low-temperature stress.

Summary: This study explores the regulatory mechanism of brassinosteroids (BRs) in enhancing chilling resistance in fruits and vegetables. The results show that exogenous 24-epibrassinolide (EBR) can delay chilling injury in peaches by reducing endogenous brassinolide accumulation and promoting expression of BR signal-related genes. Molecular assays reveal that the regulatory factor PpHDT1 exhibits opposite regulation on BR synthesis and signal pathway-related genes. The findings provide new insights into the underlying mechanism of EBR in regulating chilling resistance in postharvest peaches.

Summary: This study investigates the interplay between melatonin and nitric oxide (NO) in relation to cold stress tolerance in litchi fruit. The results show that melatonin triggers NO accumulation by activating nitric oxide synthase (NOS) and nitrate reductase (NR) in refrigerated litchi fruit, improving cold tolerance. Melatonin also reduces reactive oxygen species (ROS) accumulation and increases antioxidant activity, protecting membrane integrity. However, the effect of melatonin is partially counteracted by the NO scavenger cPTIO.

Summary: Peach fruit is susceptible to postharvest chilling injury during long-term cold storage, with more severe injury occurring at lower storage temperatures. Impairment of ethylene production and softening is greater at 0 and 5 degrees C, associated with lower expression levels of critical genes. Changes in DNA methylation levels in different genomic regions are found to regulate gene expression related to chilling injury, contributing to the development of temperature-dependent injury in postharvest peach fruit.

Summary: The study reveals that CBF1 expression is positively associated with cold tolerance in Citrus cultivars, while CBF2 or CBF3 genes did not show a clear relationship with susceptibility to CI. Light avoidance during fruit growth reduces postharvest CI in most sensitive cultivars, which may be linked to the rapid and transient enhancement in the expression of the three CBFs. This indicates that CBFs-dependent pathways mediate cold tolerance responses in sensitive Citrus, with CBF1 playing a role in natural tolerance to CI.

Summary: In this study, the effects of intermittent stepwise cooling and stepwise warming (ICW) on chilling injury (CI) in mango fruit were investigated. Results showed that ICW exposure maintained normal ripening in mango fruit during refrigeration and shelf storage. ICW inhibited electrolyte leakage rate and production of reactive oxygen species and malondialdehyde. ICW also resulted in higher activities of antioxidant enzymes and more accumulation of phenolics, flavonoids, ascorbic acid, and glutathione. Additionally, the expression of cold-responsive genes was upregulated. These physiological and biochemical changes contributed to enhanced cold tolerance and reduced CI in mango fruit.

Summary: An RNAseq analysis was performed to investigate the molecular mechanisms involved in ABA-induced postharvest cold tolerance in immature zucchini fruit. Results revealed the significance of certain metabolic and signaling pathways, as well as the role of transcription factors and genes involved in oxidative stress response and membrane and cell wall metabolism. ABA was found to regulate genes responsible for reducing oxidative stress damage, inducing cuticular wax biosynthesis, and repressing lignin biosynthesis.
