Succinic acid 2,2-dimethylhydrazide (Alar) and 2-chloroethylphosphonic acid (Ethrel) were applied to peach (Prunus persica L. cult "Redhaven") trees 7 and 9 weeks after bloom, respectively. Fruits harvested weekly throughout the growing season were examined for respiratory behavior and ethylene production with and without the addition of ethylene gas. All fruits harvested during the first (stage 1) of the two periods of rapid fruit growth, as well as mature fruits (in late stage 3), displayed a climateric respiratory pattern and produced appreciable amounts of ethylene. Alar significantly increased the ethylene production associated with ripening. Ethrel increased ethylene production only in ripening fruits not given the postharvest ethylene treatment. Both Alar and Ethrel advanced and favored uniform fruit ripening, the combination of these materials appearing to be most effective.

Pectins are synthesized and secreted to the cell wall as highly methyl-esterified polymers and demethyl-esterified by pectin methylesterases (PMEs), which are regulated by pectin methylesterase inhibitors (PMEIs). PMEs and PMEIs are involved in pectin degradation during fruit softening; however, the roles of the PME and PMEI gene families during fruit softening remain unclear. Here, 71 PME and 30 PMEI genes were identified in the peach (Prunus persica) genome and shown to be unevenly distributed on all eight chromosomes. The 71 PME genes comprised 36 Type-1 PMEs and 35 Type-2 PMEs. Transcriptome analysis showed that 11 PME and 15 PMEI genes were expressed during fruit ripening in melting flesh (MF) and stony-hard (SH) peaches. Three PME and five PMEI genes were expressed at higher levels in MF than in SH fruit and exhibited softening-associated expression patterns. Upstream regulatory cis elements of these genes related to hormone response, especially naphthaleneacetic acid and ethylene, were investigated. One PME (Prupe.7G192800) and two PMEIs (Prupe.1G114500 and Prupe.2G279800), and their promoters were identified as potential targets for future studies on the biochemical metabolism and regulation of fruit ripening. The comprehensive data generated in this study will improve our understanding of the PME and PMEI gene families in peach. However, further detailed investigation is necessary to elucidate the biochemical function and regulation mechanism of the PME and PMEI genes during peach fruit ripening.

We analyzed the transcriptomes in the shoots of five-year-old ‘Soomee’ peach trees (Prunus persica) during cold acclimation (CA), from early CA (end of October) to late CA (middle of January), and deacclimation (DA), from late CA to late DA (middle of March), to identify the genes involved in cold hardiness. Cold hardiness of the shoots increased from early to late CA, but decreased from late CA to late DA, as indicated by decreased and increased the median lethal temperature (LT50), respectively. Transcriptome analysis identified 17,208 assembled transcripts during all three stages. In total, 1891 and 3008 transcripts were differentially expressed with a |fold change| > 2 (p < 0.05) between early and late CA, and between late CA and late DA, respectively. Among them, 1522 and 2830, respectively, were functionally annotated with gene ontology (GO) terms having a greater proportion of differentially expressed genes (DEGs) associated with molecular function than biological process or cellular component categories. The biochemical pathways best represented both periods from early to late CA and from late CA to late DA were ‘metabolic pathway’ and ‘biosynthesis of secondary metabolites’. We validated these transcriptomic results by performing reverse transcription quantitative polymerase chain reaction on the selected DEGs showing significant fold changes. The relative expressions of the selected DEGs were closely related to the LT50 values of the peach tree shoots: ‘Soomee’ shoots exhibited higher relative expressions of the selected DEGs than shoots of the less cold-hardy ‘Odoroki’ peach trees. Irrespective of the cultivar, the relative expressions of the DEGs that were up- and then down-regulated during CA, from early to late CA, and DA, from late CA to late DA, were more closely correlated with cold hardiness than those of the DEGs that were down- and then up-regulated. Therefore, our results suggest that the significantly up- and then down-regulated DEGs are associated with cold hardiness in peach tree shoots. These DEGs, including early light-induced protein 1, chloroplastic, 14-kDa proline-rich protein DC2.15, glutamate dehydrogenase 2, and triacylglycerol lipase 2, could be candidate genes to determine cold hardiness.

A comparative study between melting flesh peach fruit (Prunus persica L. Batsch cvs. Royal Glory and Morettini No 2) with contrasting tissue firmness during their on-tree ripening was conducted. Such fruit were cold stored (0 °C) for 4 and 6 weeks, and subsequently transferred at 25 °C (shelf life) for up to 5 days and evaluated for quality attributes and cell wall physicochemical properties. Data were partly unexpected, since fruit of the soft cultivar (Morettini No 2) were characterized by lower exo- and endo-PG activity, lower amounts of ethylene evolution, as well as higher amounts of endogenous calcium bound in the cell wall compared to fruit of the firmer cultivar (Royal Glory). These differences may be attributed to the incidence of chilling injury symptoms, evident as loss of juiciness in Morettini No 2 fruit, while Royal Glory fruit were characterized by acceptable appearance and eating quality even after 6 weeks cold storage plus 5 days shelf life, as the fruit softened gradually without cell rupture. Overall results showed that no direct relationship between cell wall physicochemical properties and sensory attributes can be established, indicating the complexity of peach fruit ripening. Since fruit of both cultivars presented similar tissue firmness after 5 days shelf life an attempt to distinguish normal peach fruit softening from cell rupture-chilling injury also has been made in the current study.
