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 :

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.

Salicylic acid treatment improves the storability of fresh longan by regulating the metabolisms of respiration and energy SCIE

Abstract&Keyword Cite

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&Keyword Cite

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&Keyword Cite

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.

Abstract :

Longan fruit is prone to quality deterioration due to the infection by Phomopsis longanae Chi (P. longanae). This work found that acidic electrolyzed-oxidizing water (AEOW) could effectively enhance disease resistance in P. longanae-infected longans. The treatment of AEOW plus P. longanae infection attenuated fruit disease severity and maintained a higher commercially acceptable fruit of longan as compared to the longans treated only with P. longanae. Further transcriptomic analysis revealed genes associated with flavonoid and phenylpropanoid biosynthesis, MAPK signaling, and plant-pathogen interaction pathways were induced by the AEOW + P. longanae treatment. Moreover, metabolomic analysis showed that higher levels of flavonoids and phenolic acids were found in the AEOW + P. longanae-treated longans. WGCNA and gene-metabolite association networks revealed a variety of genes and metabolites that were increased by the AEOW + P. longanae treatment. These results clarify that AEOW inhibited disease occurrence in P. longanae-inoculated longans by elevating the expression of disease-resistance genes and increasing the accumulation of relevant metabolites.

Abstract :

The impacts of Bacillus amyloliquefaciens LY-1 culture broth (BLCB) on the fruit storage properties and reactive oxygen species (ROS) metabolism of postharvest 'Wuye' litchis were studied. In comparation with control fruit, BLCB-treated litchis showed a lower fruit disease index, a higher rate of commercially acceptable fruit, higher amounts of pericarp pigments (total phenolics, anthocyanin, carotenoid, chlorophyll and flavonoid), higher chromaticity C, a*, b* and L* values but lower hue angle h degrees of fruit surface. Additionally, BLCB-treated litchis exhibited lower malonaldehyde (MDA) accumulation and superoxide anion radical (O2.-) production rate, higher APX, CAT and SOD activities, higher GSH and AsA amounts, higher reducing power, and higher ability of scavenging DPPH radical. Furthermore, the pericarp browning index and fruit disease index were positively correlated with O2.- production rate. These findings suggested that BLCB treatment increased the storability of postharvest litchi fruit through enhancing scavenging capacity of ROS and inhibiting overaccumulation of ROS.

The role of respiration metabolism in dicyclohexylcarbodiimide and disodium succinate regulating the pulp breakdown occurrence of fresh longan (Dimocarpus longan Lour.) during storage SCIE

Abstract&Keyword Cite

Abstract :

Compared to control longan, on day 6, DCC-treated longan presented 18 %, 2 %, 15 %, 34 %, 21 %, 26 % and 10 % higher levels of pulp breakdown index, fruit respiration rate, PGI, SDH, NAD, NADH and QH2, respectively. Meanwhile, DCC-treated longan displayed 25 %, 5 %, 8 % and 12 % higher activities of respiratory terminal oxidases including CCO, AOX, PPO and AAO, respectively. However, DCC-treated longan presented 9 %, 27 %, 24 %, 25 % and 16 % lower levels of NADK, G-6-PDH + 6-PGDH, NADP, NADPH and Q, respectively. These data indicate that DCC-hastened longan pulp breakdown occurrence was owing to the diminished PPP, and the elevated EMP, TCA cycle and CCP, thereby leading to an increased respiration rate. However, DS treatment displayed contrary effects, indicating DS restrained longan pulp breakdown occurrence through diminishing the respiration metabolism and depressing the respiration rate of fresh longan.

Low temperature delays longan pulp breakdown through DlMYB108-DlPME17 transcriptional regulation SCIE
期刊论文 | 2025 , 232 | POSTHARVEST BIOLOGY AND TECHNOLOGY
Abstract&Keyword Cite

Abstract :

Postharvest pulp degradation significantly constrains the shelf life and commercial value of longan fruits. This investigation revealed a temperature-responsive transcriptional network centered on the DlMYB108-DlPME17 regulatory module that controls longan pulp deterioration. Physiological analyses demonstrated that 10 degrees C effectively delayed pulp degradation by maintaining cell wall integrity and inhibiting hydrolase activities compared with 25 degrees C. Transcriptomic profiling identified 9372 differentially expressed genes, with cell wall metabolism being significantly enriched. Among these, DlPME17 (Dil.04g002100.1) exhibited substantial upregulation correlating with degradation progression. Molecular characterization identified DlMYB108 as a nuclear-localized transcriptional activator demonstrating low-temperature inhibitory expression. DlMYB108 directly binds to the DlPME17 promoter and activates its expression. These findings establish DlMYB108 as a critical regulator of pectin disassembly through transcriptional control of DlPME17, offering insights into the molecular mechanisms underlying postharvest longan quality deterioration.
