“…Ripening limits fruit shelf‐life to a week or less, after which the fruit deteriorates. To extend its shelf‐life, mature fruit can be stored between 0 and 5°C for few weeks, which delay the ripening process by decreasing the fruit enzymatic activity and slowing down harvested fruit respiration (Lauxmann et al , Pedreschi and Lurie ). For chilling sensitive varieties, the ripe fruit that follows cold storage displays the chilling injury syndrome, a series of physiological disorders at the fruit mesocarp and epidermis that can include mealiness (Lurie and Crisosto ).…”

Chilling injury represents a major constrain for crops productivity. Prunus persica, one of the most relevant rosacea crops, have early season varieties that are resistant to chilling injury, in contrast to late season varieties, which display chilling symptoms such as mealiness (dry, sandy fruit mesocarp) after prolonged storage at chilling temperatures. To uncover the molecular processes related to the ability of early varieties to withstand mealiness, postharvest and genome-wide RNA-seq assessments were performed in two early and two late varieties. Differences in juice content and ethylene biosynthesis were detected among early and late season fruits that became mealy after exposed to prolonged chilling. Principal component and data distribution analysis revealed that cold-stored late variety fruit displayed an exacerbated and unique transcriptome profile when compared to any other postharvest condition. A differential expression analysis performed using an empirical Bayes mixture modeling approach followed by co-expression and functional enrichment analysis uncover processes related to ethylene, lipids, cell wall, carotenoids and DNA metabolism, light response, and plastid homeostasis associated to the susceptibility or resistance of P. persica varieties to chilling stress. Several of the genes related to these processes are in quantitative trait loci (QTL) associated to mealiness in P. persica. Together, these analyses exemplify how P. persica can be used as a model for studying chilling stress in plants.

“…The underlying molecular mechanisms of ethylene action have been studied during fruit development and ripening [3][4][5][6][7]. In tomato, a model organism to study fruit ripening, it is proposed that the TF CNR and in reactive oxygen species, and down-regulation of ethylene biosynthesis [25,26]. The plant responses to LT have typically been studied in vegetative tissues or in chilling sensitive fruit.…”

Low temperature (LT) treatments enhance ethylene production and ripening rate in the European pear (Pyrus communis L.). However, the underlying molecular mechanisms are not well understood. This study aims to identify genes responsible for ripening enhancement by LT. To this end, the transcriptome of 'Bartlett' pears treated with LT (0°C or 10°C for up to 14 d), which results in faster ripening, and control pears without conditioning treatment was analyzed. LT conditioned pears reached eating firmness (18N) in 6 d while control pears took about 12 d when left to ripen at 20°C. We identified 8,536 differentially expressed (DE) genes between the 0°C-treated and control fruit, and 7,938 DE genes between the 10°C-treated and control fruit. In an attempt to differentiate temperature-induced vs. ethylene-responsive pathways, we also monitored gene expression in fruit sequentially treated with 1-MCP then exposed to low temperature. This analysis revealed that genes associated with jasmonic acid biosynthesis and signaling, as well as the transcription factors TCP9a, TCP9b, CBF1, CBF4, AGL24, MYB1R1, and HsfB2b could be involved in the LT-mediated enhancement of ripening independently or upstream of ethylene.

“…Chilling injury is a physiological alteration that becomes evident when the fruit is taken off from the fridge and reaches the consumers. The molecular basis of chilling injury and the signal transduction networks of the chilling response are poorly understood (Sapitnitskaya et al , Pedreschi and Lurie ). In addition, the diversity of chilling injury symptoms of tropical and subtropical fruits and vegetables suggests a multitude of responses to low temperature (Wang ).…”

Small heat shock proteins and the postharvest chilling tolerance of tomato fruit

Plants have the largest number of small heat shock proteins (sHsps) (15-42 kDa) among eukaryotes, but little is known about their function in vivo. They accumulate in response to different stresses, and specific sHsps are also expressed during developmental processes such as seed development, germination, and ripening. The presence of organelle-specific sHsps appears to be unique to plants. The sHsps expression is regulated by heat stress transcription factors (Hsfs). In this work, it was explored the role of sHsps in the chilling injury of tomato fruit. The level of transcripts and proteins of cytoplasmic and organellar sHsps was monitored in fruit during ripening and after cold storage (4 weeks at 4°C). Expression of HsfA1, HsfA2, HsfA3, and HsfB1 was also examined. Two cultivars of tomato (Solanum lycopersicum) contrasting in chilling tolerance were assayed: Micro-Tom (chilling-tolerant) and Minitomato (chilling-sensitive). Results showed that sHsps were induced during ripening in fruit from both cultivars. However, sHsps were induced in Micro-Tom fruit but not in Minitomato fruit after storage at a low temperature. In particular, sHsp 17.4-CII and sHsp23.8-M transcripts strongly accumulated in Micro-Tom fruit and HsfA3 transcript diminished after cold storage. These data suggest that sHsps may be involved in the protection mechanisms against chilling stress and substantiate the hypothesis that sHsps may participate in the mechanism of tomato genotype chilling tolerance.
