Postharvest chilling injury (PCI) reduces fruit quality and shelf-life in tomato ( Solanum lycopersicum L.). PCI has been traditionally studied in the pericarp, however its development is likely heterogeneous in different fruit tissues. To gain insight into PCI’s spatio-temporal development, we used postharvest biomarkers e.g. respiration and ethylene rates, ion leakage etc., to confirm the occurrence of PCI, and compared these data with molecular (gene expression), biophysical (MRI data) and biochemical parameters (Malondialdehyde (MDA) and starch content) from the pericarp or columella. Tissues were stored at control (12.5 °C) or PCI-inducing temperatures (2.5 or 5 °C) followed by rewarming at 20 °C. MRI and ion leakage revealed that cold irreversibly impairs ripening-associated membrane liquefaction; MRI also showed that the internal and external fruit tissues responded differently to cold. MDA and especially starch contents, were affected by chilling in a tissue-specific manner. The expression of the six genes studied: ACO1 and ACS2 (ripening), CBF1 (cold response ), DHN , AOX1a and LoxB (stress-related) showed non-overlapping temporal and spatially-specific responses. Overall, the data highlighted the interconnectedness of fruit cold response and ripening, and showed how cold stress reconfigures the latter. They further underscored that multidimensional spatial and temporal biological studies are needed to develop effective solutions to PCI.

Postharvest handling of tomato (Solanum lycopersicum L.), specifically low-temperature storage and early harvest are used to extend shelf life, but often reduce fruit quality. Recent work suggests that DNA methylation dynamics influences fruit ripening through the demethylase SlDML2 gene. However, the influence of postharvest handling on DNA methylation in relation to fruit quality is unclear. This work aimed to clarify these issues by analyzing DNA methylation using methyl-sensitive amplification polymorphism (MSAP), semi-quantitative transcriptional analysis of marker genes for fruit quality (RIN; RIPENING INHIBITOR) and DNA methylation (SlDML2; Solanum lycopersicum L. DNA demethylase 2), and, fruit biochemical quality biomarkers. Multivariate analysis of these data supported the view that DNA methylation of fruit was influenced more by postharvest handling than ripening stage, however, fruit quality was influenced mainly by ripening. Fruit chilled postharvest were distinct in their DNA methylation state and quality characteristics, which implied that these three phenomena i.e., chilling, methylation, and quality are highly connected. In addition, different postharvest handling methods modulated SlDML2 transcript levels but had little effect on the level of RIN transcripts in fruit that reached the Turning stage after early harvest, and cold storage. These data collectively helped to advance our interpretation of tomato fruit ripening. In conclusion, our findings revealed that postharvest-induced variation in fruit quality is in relation to DNA methylation. Long-term this work will help better connect physiological changes in tomato fruit to events happening at the molecular level.

Chilling Injury in Tropical Crops after Harvest

Tropical crops suffer from chilling injury after harvest, which has historically limited their global trade. The primary cause of chilling injury relates to membrane dysfunction leading to altered Ca2+flux and upregulation of cold‐regulated genes via C‐repeat binding factors (CBFs). Secondary damage results from generation of free radicals. Chilling injury leads to a diversity of internal and external symptoms in tropical crops. The most serious are those which occur only internally or take time to display after fresh products leave the chilling environment, as these symptoms are likely to lead to product rejection after purchase. Techniques for the detection of chilling injury by non‐destructive technologies are reviewed. A wide range of techniques has been tested empirically for reducing chilling susceptibility in tropical crops (step‐down cooling, hormetic treatments, intermittent warming, atmosphere modification, chemical treatments, and pre‐harvest manipulation) and is reviewed here. Faster progress may be possible if treatments can be based on knowledge of underlying mechanisms; for example, maximal heat shock protein gene expression may be an indicator of effective heat treatments. Options for introducing greater chilling tolerance through breeding are discussed, using wild relatives or introduced CBFs. Improved technologies are already leading to increased trade in tropical products which is beneficial for tropical economies.
