The effect of 1‐methylcyclopropene (1‐MCP) treatment on postharvest quality of French prune (Prunus domestica L.) during low temperature storage was investigated. French prunes were exposed to 1.2 μl/L 1‐MCP and stored at 1 ± 1°C under 90 ± 5% RH. The physiological and biochemical indexes were measured and recorded weekly throughout the experimental period. Our experimental results showed that 1‐MCP had a significant effect on maintaining fruit hardness (~20%), titratable acidity (~29%), ascorbic acid (~18%), total soluble solid (~21%), anthocyanin, retarding moisture loss (~44%), and delaying the color changes and harvest ripening (~7 d) as compared to non‐1‐MCP treated fruit. Furthermore, 1‐MCP treatment significantly inhibited malondialdehyde (MDA) production (~33%) and maintained the total phenolic content. Therefore, 1‐MCP, an ethylene antagonist, could effectively maintain postharvest quality of prune during storage at low temperature. Practical applications French prune (Prunus domestica L.) is very popular in the world, because it has the very high nutritional value. However, the harvested French prunes tend to soften rapidly at ambient temperature. Low temperature storage is beneficial to prolong the postharvest life of prunes. Besides, 1‐methylcyclopropene (1‐MCP) is effective in delaying fruit ripening and extending the postharvest life. The aim of this study is to evaluate the influence of 1‐MCP on postharvest quality of French prune during low temperature storage. In general, 1‐MCP could effectively maintain postharvest quality of prune during storage at low temperature.

“…BZR1 increased over time in 'D'Anjou' and decreased over time in 'Bartlett' [40] (Supplementary File 3). These observations may provide further insight into the cultivar specific nature of ripening in pear, as 'D'Anjou' is known to be inherently more recalcitrant to ripening [41]. The different ripening trajectories apparent from analysis in this study are congruent with the different vectors followed by the two cultivars in the recent study, which used NMDS analysis to evaluate the relationship between ripening and genes related to the process [26].…”

European pear (Pyrus communis L.) cultivars require a genetically pre-determined duration of cold-temperature exposure to induce autocatalytic system 2 ethylene biosynthesis and subsequent fruit ripening. The physiological responses of pear to cold-temperature-induced ripening have been well characterized, but the molecular mechanisms underlying this phenomenon continue to be elucidated. This study employed established cold temperature conditioning treatments for ripening of two pear cultivars, 'D'Anjou' and 'Bartlett'. Using a time-course transcriptomics approach, global gene expression responses of each cultivar were assessed at four different developmental stages during the cold conditioning process. Differential expression, functional annotation, and gene ontology enrichment analyses were performed. Interestingly, evidence for the involvement of cold-induced, vernalization-related genes and repressors of endodormancy release was found. These genes have not previously been described to play a role in fruit during the ripening transition. The resulting data provide insight into cultivar-specific mechanisms of cold-induced transcriptional regulation of ripening in European pear, as well as a unique comparative analysis of the two cultivars with very different cold conditioning requirements.For both cultivars, fruit softening accelerated once the fruit was transferred to 20°C. The rate of softening was more rapid for 'Bartlett' than 'D'Anjou'. RNAseq Assembly AnalysisRNAseq assembly generated 140077 contigs (Supplementary File 1). In the OmicsBox suite, the maSigPro R package was used to conduct time course differential expression analyses for both cultivars. 17,711 differentially expressed contigs (p<0.05) were identified for 'D'Anjou', with 7,174 of these contigs exhibiting significant linear or quadratic trends over time (R>0.8). In 'Bartlett' 31,481 contigs were identified as being differentially expressed, with 7,174 contigs exhibiting significant quadratic or linear trends over time (R>0.8) (Supplementary File 2). Similarities and differences in expression trends of contigs of interest between 'D'Anjou' and 'Bartlett', as well as expression patterns of differentially expressed contigs (DECs) associated with ethylene and phytohormone metabolism, abscisic acid metabolism, TCA cycle, respiration, were assessed. Additionally, in order to better understand the mechanisms underlying the chilling requirement for ripening in Pyrus, the expression of genes associated with: vernalization, flowering, dormancy, and other processes directly induced by cold/chilling were observed. Preclimacteric expression of AOX1 peaked during conditioning prior to onset of ripening (Figure 1), supporting the hypothesis. Additional key genes, including those that mediate vernalization and endodormancy release were also observed to be differentially expressed. Detailed analysis of RNAseq results and enriched gene ontologies related to phytohormone metabolism and coldresponse pathways are discussed in detail in the following sections.
