Abstract ：
Recent studies have reported that energy level is an important factor influencing the quality of harvested fruit. 2, 4-Dinitrophenol (DNP) is an inhibitor of oxidative phosphorylation that reduces energy level, whereas, adenosine triphosphate (ATP) is an energy substance that can increase energy level. This work investigated the role of energy status, ion transport and respiration metabolism on the development of pulp breakdown in harvested longan treated by DNP and ATP. Results showed that, in comparison to control longan samples, DNP application worsened pulp breakdown and increased adenosine monophosphate level. Whereas, DNP reduced the levels of energy charge, ATP, adenosine diphosphate, H+ -ATPase, Ca2+-ATPase and Mg2+-ATPase. Furthermore, DNP treatment strengthened the respiration rate, increased the levels of phosphoglucose isomerase, succinate dehydrogenase, cytochrome C oxidase, ascorbic acid oxidase, polyphenol oxidase, alternative oxidase, nicotinamide adenine dinucleotide (NAD), and the reduced form of NAD (NADH), but decreased the levels of NAD kinase (NADK), nicotinamide adenine dinucleotide phosphate (NADP), the reduced form of NADP (NADPH), and glucose-6-phosphate dehydrogenase + 6-phosphogluconate dehydrogenase. These results suggest that DNP treatment induced energy deficiency, impairing ion transport capacity and disrupting the ion transport system, which damaged cell structure. This disruption further perturbed the respiration metabolism by suppressing the pentose phosphate pathway while enhancing the Embden Meyerhof Parnas, tricarboxylic acid cycle, cytochrome pathway, and alternate oxidation pathway. These changes increased the consumption of organic nutrients, thus worsening longan pulp breakdown. However, ATP treatment had the opposite effects, providing sufficient energy to maintain the balanced ion transport and respiration metabolism. This maintained cell structure, reduced nutrition consumption, and mitigated longan pulp breakdown.

Abstract ：
Longan is susceptible to pericarp browning, which reduces its market value. The effects of bongkrekic acid (BKA, an energy transport inhibitor) or adenosine triphosphate (ATP) treatment on the pericarp browning, energy status, and the metabolisms of ROS, membrane lipid and phenolics in postharvest longan fruit were explored. Compared with the control group, BKA-treated longans displayed higher pericarp browning index, but lower levels of ATP and energy charge. Additionally, BKA treatment attenuated the ROS scavenging ability of longans, as evidenced by lower activities of SOD, CAT and APX, as well as lower levels of AsA and GSH, while concurrently increased O2-. production rate, H2O2 and MDA levels. Besides, BKA treatment raised the activities of PLD, lipase and LOX, as well as the amounts of PA and SFAs, while lowered the levels of PC, PI and USFAs, aggravated membrane lipid peroxidation and degradation, resulting in the disruption of membrane compartmentation, allowing PPO directly contact to phenolic substrates and causing pigment degradation. These were manifested by the reduced contents of total phenolics, flavonoid, anthocyanin, carotenoid and chlorophyll, and the declined values of chromaticity L*, a* and b*, which exacerbated longan pericarp browning. Whereas, ATP treatment presented the opposite effects. These outcomes indicated that BKA treatment-induced the suppression of energy transport could accelerate longan pericarp browning via lowering the energy level and thereafter stimulating the ROS over accumulation, membrane lipid peroxidation and degradation, thereby leading to enzymatic browning. However, ATP treatment-postponed longan pericarp browning was because ATP treatment stimulated energy transport, sustained higher levels of energy and antioxidant capacity, thereby diminishing ROS accumulation, maintaining cell membrane integrity, and restraining enzymatic browning.

Abstract ：
Chinese olives (Canarium album L.) are susceptible to chilling injury (CI) at inappropriate low temperature, leading to quality deterioration and loss of nutritional and commercial values. Given that cell wall polysaccharides (CWP) play a crucial role in maintaining fruit texture and quality during postharvest storage, we systematically explored the changes of quality properties, CWP metabolism, and CI development in Chinese olives during cold storage at 8 degrees C and 2 degrees C. Compared with 8 degrees C-stored Chinese olives, 2 degrees C-stored fruit presented a higher CI index, the lower levels of commercially acceptable fruit percentage, total soluble solids, total soluble sugar, sucrose, titratable acid, and vitamin C, and the higher levels of weight loss percentage and reducing sugar during cold storage. Additionally, 2 degrees C-stored fruit showed the higher levels of pectin esterase, polygalacturonase, beta-galactosidase, cellulase, xyloglucan endotransglycosylase, and water-soluble pectin, but the lower values of cell wall materials, covalent-soluble pectin, ionic-soluble pectin, cellulose, and hemicellulose. These results indicate that the inappropriate low temperature (2 degrees C) exacerbated the CI occurrence, accelerated the nutrient loss and the quality deterioration, and aggravated the CWP disassembly by stimulating the activities of cell wall-degrading enzymes in Chinese olives during cold storage.

Abstract ：
This research aimed to compare the fruit storability and quality differences between the 'Fuyan' and 'Dongbi' varieties of longan (Dimocarpus longan Lour.) by assaying their antioxidant system and disease defense systems. The results showed that, compared to 'Fuyan' fruit, during storage, 'Dongbi' fruit exhibited superior storability and appearance, characterized by lower levels of fruit disease, pulp breakdown, pericarp browning, and weight loss, alongside higher pericarp color, brightness, pigments, pulp nutrient content, and commercial acceptability of fruit. Additionally, 'Dongbi' longans exhibited lower ROS accumulation and MDA level, higher levels of antioxidants (AsA, GSH), antioxidant enzymes (SOD, CAT, APX), reducing power, and DPPH center dot scavenging ability. Besides, 'Dongbi' longans retained higher levels of secondary metabolites (lignin, total phenolics, flavonoid), PRMEs (PAL, C4H, 4-CL, CAD, POD), and PRs (CHI, GLU). Therefore, the enhanced storage stability of 'Dongbi' longans may be attributed to the synergistic effects of an improved antioxidant system, phenylpropanoid pathway, and PRs.

Abstract ：
This work investigated how salicylic acid (SA) treatment enhanced the storage quality of longan fruit by affecting its respiration and energy metabolism. Compared to control longan, SA-treated longan exhibited higher levels of commercially acceptable fruit rate, sucrose, vitamin C, TSS, and total soluble sugar, but lower levels of fruit disease index, pulp breakdown index, weight loss, TA, and reducing sugar. Additionally, SA treatment resulted in lower fruit respiration rate, lower activities of the critical enzymes involved in respiratory pathways (PGI, SDH, CCO, AAO), lower values of NADH and NAD, higher activities of enzymes (NADK, G-6-PDH + 6-PGDH), and higher amounts of NADPH and NADP. Besides, SA-treated longan showed higher levels of ATP, ADP, and energy charge, but lower AMP level, along with higher activities of H+-ATPase, Ca2+-ATPase, and Mg2+-ATPase in mitochondrial, plasma, and vacuolar membranes. These data indicated that SA treatment-maintained the storage attributes of postharvest longan was due to the weakened respiratory intensity, the reduced consumption of nutrients, the inhibited respiratory pathways of EMP-TCA cycle, and the enhanced respiratory pathway of PPP. Additionally, SA treatment retained higher levels of ATPase activity and energy status to maintain cellular ionic balance and protect membrane integrity, ultimately improved the storability of fresh longan during storage.

Abstract ：
Banana fruit is susceptible to chilling injury (CI) during cold storage, which causes quality deterioration and commodity value decline. Here, the effects of melatonin on CI alleviation and reactive oxygen species (ROS) metabolism in postharvest banana were studied. The results displayed that 500 mu mol L-1 melatonin treatment effectively inhibited CI development in cold-stored banana during the 96 h of storage. Additionally, lower O2.productive rate and H2O2 content, but higher contents of ascorbic acid (AsA) and glutathione (GSH) were found in melatonin-treated banana, compared with control fruits. Also, melatonin inhibited the declined activities of antioxidant enzymes. Moreover, a total of 1858 and 330 differentially expressed genes (DEGs) were identified between the comparison of CK48h (control bananas at 48 h) and MT48h (melatonin-treated bananas at 48 h), and CK96h (control bananas at 96 h) and MT96h (melatonin-treated bananas at 96 h) through comparative transcriptome analysis of banana fruit, respectively. Further KEGG displayed that DEGs were enriched in secondary metabolites biosynthesis, MAPK signaling pathway-plant and plant hormone signal transduction. The transcriptome expression profiling and RT-qPCR exhibited melatonin treatment improved the expressions of antioxidant enzyme genes (MaSOD, MaCAT, MaAPX and MaGR) but inhibited the expression of ROS production gene (MaRBOH). Collectively, these findings provide a comprehensive view of ROS metabolism associated with the melatonin-alleviated CI in cold-stored banana fruit.

Abstract ：
To understand the underlying mechanism of the organic acid accumulation of postharvest longan fruit, integrative analyses of transcriptome and metabolome were performed in the fruit of two longan varieties ('Fuyan' and 'Dongbi') with different storability. Compared with 'Dongbi' longan, the 'Fuyan' cultivar exhibited higher fruit respiration rate, pulp breakdown index, and TA content, but a lower TSS content during storage. Targeted metabolomic analysis revealed that, in comparison to 'Dongbi' longan, during storage, 'Fuyan' longan accumulated higher levels of four organic acids, including 3-phenyllactic acid, lactate, succinic acid, and oxaloacetate. Transcriptomic analysis showed that DEGs between 'Fuyan' and 'Dongbi' longans were primarily enriched in respiration metabolism pathways, including glycolysis, gluconeogenesis, and the TCA cycle. Additionally, WGCNA identified hub genes involved in these metabolic pathways. RT-qPCR analysis indicated that the expression of related genes (DlLDH, DlACL, DlPEPC, DlMDH, DlAST and DlSCS) was upregulated in 'Fuyan' longan compared with 'Dongbi' longan during storage. These findings suggest that the increase in longan pulp acidity is attributed to organic acid accumulation and an enhanced respiration metabolism, resulting in the poor storability of 'Fuyan' longan during storage.

Abstract ：
Chilling injury (CI) is one of the main symptoms of quality deterioration in cold-stored Chinese olives, leading to the rapid declines of nutrition and commercial value. This work explored the efficacy of 1.0 mM gamma-aminobutyric acid (GABA) treatment on the respiratory and energy metabolisms in Chinese olives during cold storage at 2 degrees C and its relationship with CI development and quality attributes. The Chinese olives were immersed in distilled water and 1.0 mM GABA solution for 10 min, respectively. Compared with the control samples, the GABA-treated Chinese olives presented lower levels of fruit CI index and weight loss percentage, and lower contents of pericarp carotenoid and pulp reducing sugar. Conversely, the GABA-treated samples showed a higher percentage of the commercially acceptable fruit, a higher pericarp h degrees value, higher levels of pericarp chlorophyll and pulp total soluble solids, titratable acidity, tannin, vitamin C, total soluble sugar, and sucrose. Additionally, the GABAtreated samples showed lower respiration rate, lower activities of phosphoglucose isomerase, succinate dehydrogenase, cytochrome C oxidase, and ascorbic acid oxidase, lower values of nicotinamide adenine dinucleotide (NAD) and the reduced form of NAD (NADH), and lower content of adenosine monophosphate, but higher activities of glucose-6-phosphate dehydrogenase + 6-phosphogluconate dehydrogenase, nicotinamide adenine dinucleotide kinase, H+, Ca2+, and Mg2+-ATPase, higher values of nicotinamide adenine dinucleotide phosphate (NADP) and the reduced form of NADP (NADPH), and higher contents of adenosine triphosphate, adenosine diphosphate, and energy charge. These findings elucidate that the alleviating effects of GABA on the CI occurrence and quality deterioration in Chinese olives during cold storage are related to the inhibition of respiratory metabolism and the maintenance of a higher energy status.

Abstract ：
Banana is a cold-sensitive fruit, which exhibits vulnerability to chilling injury (CI), causing browning, pitting, even abnormal ripening, resulting in quality deterioration and economic loss. CI development of banana fruit was caused by membrane integrity damage and was related to the enzymatic and genetic manipulation of membrane lipid metabolism pathway. The involvement of Ethylene Response Factor (ERF) transcription factors (TFs) in membrane lipid-mediated CI development of cold-sensitive fruit, such as banana, remains largely unknown. In this study, we found that cold treatment increased CI index, cell membrane permeability and MDA content, decreased hue angle (h degrees) value. The expressions of membrane lipids metabolism genes, including MaDGK, MaPLA, MaLipase and MaLOX, were upregulated by cold treatment. Also, two banana ERF TFs, designated as MaERF9 and MaERF113, were induced by cold environment and displayed transactivation activities. Additionally, the electrophoretic mobility shift assay (EMSA) and transient expression analysis showed that MaERF9 and MaERF113 directly bound to the GCC-box elements in the promoters of MaDGK, MaPLA, MaLipase and MaLOX, and activated their expressions. These findings imply that MaERF9 and MaERF113 involved in CI development of banana fruit, via affecting membrane lipid metabolism. Collectively, our results provide new insights into the transcriptional regulation network regulating CI development of banana fruit.

Abstract ：
The quality deterioration in pulp of postharvest longan fruit is related to the increase in acidity during storage. However, the main organic acids and their regulatory mechanisms are still unrevealed. This study explored the impacts of 2,4-dinitrophenol (DNP) and adenosine triphosphate (ATP) treatments on the energy level and their influences on titratable acid (TA) contents in longan pulp. Compared with the control samples, lower levels of pulp energy charge, ATP and total soluble solids (TSS), but higher fruit respiration rate, pulp breakdown index and TA content were found in DNP-treated longans. Moreover, higher levels of four organic acids (fumaric acid, lactate, succinic acid, and oxaloacetate) were presented in DNP-treated samples through the analysis of targeted metabolome. However, the ATP treatment showed the opposite effects. The transcriptome analysis showed that differentially expressed genes (DEGs) among the three treatment groups were predominantly enriched in respiration metabolism pathways, including glycolysis, gluconeogenesis and tricarboxylic acid (TCA) cycle. In addition, weighted gene co-expression network analysis (WGCNA) identified four genes (DlSDH, DlLDH, DlSCS, and DlMDH) associated with the aforementioned metabolic pathways. RT-qPCR results exhibited that, during storage, these four genes in longan pulp were upregulated by DNP treatment and downregulated by ATP treatment. Therefore, energy deficit could promote the expression of DlSDH, DlLDH, DlSCS, and DlMDH, enhancing the metabolisms of glycolysis, gluconeogenesis, and TCA cycle, thereby accelerating the increase of organic acids in pulp of fresh longan during storage. This work revealed the main organic acids, the metabolic pathways, and the key genes involved in the increased acidity in pulp of postharvest longan fruit, as well as expanded our knowledge of energy regulating longan fruit quality and its relationship with the metabolism of organic acids.
