To elucidate the regulatory role of jasmonic acid (JA) in the cold stress response in plum fruit, changes in flesh coloration and associated biochemical metabolisms were investigated in yellow-fleshed ‘Hongcui’ plum treated with methyl jasmonate (MeJA) or its antagonist sodium diethyldithiocarbamate (DIECA). Compared with untreated and DIECA-treated fruit, MeJA-treated plums developed more intense and earlier flesh reddening during cold storage and the subsequent shelf life. MeJA treatment elicited the endogenous ethylene production and jasmonic acid level. The contents of total phenolics, flavonoids, anthocyanins, and the antioxidant capacity were markedly enhanced during the flesh-reddening process in MeJA-treated fruit, accompanied by the increased activities of key enzymes such as phenylalanine ammonia lyase (PAL), dihydroflavonol-4-reductase (DFR), anthocyanin synthase (ANS), and UDP-glucose: flavonoid 3-<em>O</em>-glucosyltransferase (UFGT). Gene enrichment analysis revealed an overall up-regulation trend of gene transcription associated with <em>PsPAL</em>, <em>PsDFR</em>, <em>PsANS</em>, <em>PsUFGT</em>, <em>PsACS</em>, and <em>PsACO</em>, and jasmonic acid biosynthesis pathway in the plums after MeJA treatment. Non-targeted metabolomics analysis revealed that the MeJA treatment increased the abundance of specific flavonoids, notably cyanidin-3-<em>O</em>-rutinoside, delphinidin-3-<em>O</em>-glucoside, dihydroquercetin, and rutin. Integrative analysis of transcriptomic and metabolomic data indicated strong correlations between specific differentially expressed genes (DEGs) and differentially accumulated metabolites (DAMs) within the anthocyanin biosynthesis pathway. These findings underscore the potential of MeJA as a promising postharvest method to enhance both the appearance and functional properties of plum fruit.</div></div>","PeriodicalId":20328,"journal":{"name":"Postharvest Biology and Technology","volume":"234 ","pages":"Article 114159"},"PeriodicalIF":6.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon BABA treatment, PpIBI1 is recruited to the pattern-recognition receptor (PRR) co-receptor PpBAK1, triggering activation of the PpRac1/2–PpRBOHD/F component and a rapid burst of reactive oxygen species (ROS)-a hallmark of early pattern-triggered immunity (PTI)-like responses.

Molecular evidence from overexpression and CRISPR/Cas9 knockout confirms that PpIBI1 exerts a dual function by mediating the early ROS burst and later activating the SA-dependent defense. Collectively, these findings outline a sequential pathway in which PpIBI1 activates PpBAK1 to initiate a PTI-related ROS burst, followed by nuclear interaction with PpTCP2 to induce SA-dependent SAR.

In this study, postharvest cucumber fruit was treated with melatonin (MT) prior to cold storage. We found that MT treatment significantly reduced CI development and maintained high total soluble solids content throughout cold storage. Metabolomics data indicated that MT treatment significantly altered the metabolite profiles in cold-stored cucumber fruit. Specifically, the contents of 11 sugar-related metabolites were significantly higher in MT-treated fruit compared to the control at both 6 d and 12 d of cold storage. Of these, 8 were glycosides, such as n-propyl β-lactoside, (4S)-α-terpineol 8-O-β-<span>D</span>-glucopyranoside, limonin 17-β-<span>D</span>-glucopyranoside and kankanoside P, suggesting that MT treatment promotes sugar accumulation, particularly of glycosides. Transcriptomic data revealed that the differentially expressed genes (DEGs) upregulated by MT treatment were highly associated with sugar biosynthesis or metabolism pathways, as well as various types of glycan biosynthesis pathways. Weighted gene co-expression network analysis and gene set enrichment analysis further confirmed the overall upregulation of DEGs in glycan biosynthesis pathway by MT treatment. A joint analysis combining metabolome and transcriptome data showed high correlations between MT-modulated metabolites and DEGs in glycan biosynthesis pathway. Furthermore, RT-qPCR analysis demonstrated that MT treatment significantly upregulated the expression of 6 representative genes involved in glycan biosynthesis. Taken together, these results strongly suggest that MT treatment induces chilling tolerance in cucumber fruit during cold storage, likely by promoting glycoside accumulation and inducing glycosidation. The accumulated glycosides would maintain osmotic equilibrium across cell membranes or enhance the biological activities of various molecules, thereby bolstering resistance to cold stress.</div></div>","PeriodicalId":20328,"journal":{"name":"Postharvest Biology and Technology","volume":"234 ","pages":"Article 114134"},"PeriodicalIF":6.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145786647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
