Biaxially oriented polyethylene (BOPE) is a high-strength, lightweight polyethylene material with superior barrier properties. In this study, peaches were packaged using either polyethylene (PE) or BOPE film. The peaches packaged in BOPE film maintained better firmness, color retention, antioxidant content, and nutritional quality than control peaches and those packaged in PE film. Transcriptome sequencing revealed 1041 differentially expressed genes in BOPE-packaged fruit compared with that in the control, and these were enriched in the pyruvate metabolism, flavonoid biosynthesis, and glutathione metabolism pathways. Physiological analyses demonstrated that BOPE packaging reduced malondialdehyde accumulation and increased peroxidase and phenylalanine ammonia-lyase activity, potentially limiting membrane peroxidation and senescence. BOPE-packaged fruit also retained higher levels of soluble sugars, reducing sugars, free amino acids, and proline, which are critical for fruit flavor and stress adaptation. Together, these results underscore the potential of BOPE as a novel packaging material for the preservation of fruits and vegetables.

Fatty acid composition is crucial for determining meat quality. Pigeon meat, renowned for its tender texture, high protein content, and abundant polyunsaturated fatty acid (PUFAs), yet the developmental dynamics and molecular mechanisms of intramuscular fatty acid deposition remain unclear. Previous studies suggest that lipid metabolism is often governed by coordinated gene expression programs. Therefore, we hypothesized that fatty acid profiles in pigeon muscle are regulated by gene co-expression modules identifiable via weighted gene co-expression network analysis (WGCNA). To test this, we analyzed pectoral muscles from pigeons at five developmental stages (28 days to 48 months) using gas chromatography–mass spectrometry (GC–MS) and transcriptomic sequencing. A total of 39 fatty acids were identified, with key PUFAs such as DHA increasing and EPA decreasing over time, while overall MUFAs declined and PUFAs peaked at 6 months, revealing distinct stage-dependent patterns in fatty acid composition. WGCNA revealed that three gene modules (green, yellow, turquoise) were significantly associated with fatty acid traits. GO Enrichment analysis indicated their involvement in ribosome activity, mitochondrial pathways, and unsaturated fatty acid biosynthesis, while KEGG pathway highlighted oxidative phosphorylation and phosphatidylinositol signaling. Protein-protein interaction (PPI) analysis pinpointed hub genes, including RPS16, NDUFS6, RHOJ, and NUDT12 as key regulators of fatty acid metabolism. This study provides the first co-expression network linking fatty acid composition with transcriptional regulation in pigeons, broadening WGCNA application in avian lipid metabolism. The findings offer new insights into gene networks underlying lipid deposition and suggest targets for improving meat quality through molecular breeding.

Fen-flavor Baijiu is produced via two fermentation rounds (Dacha and Ercha), and quality is shaped by microbes in fermented grains. We hypothesized that the two rounds select distinct lactic acid bacteria (LAB) consortia with different metabolic potentials that associate with stage-specific metabolites and flavor compounds. We profiled 24 fermented-grain samples using shotgun metagenomics and untargeted metabolomics. Ercha showed lower alpha-diversity and a composition distinct from Dacha. Lactobacillus acetotolerans dominated Dacha, whereas Acetilactobacillus jinshanensis dominated Ercha. We detected 225 differential metabolites; 12 involved in flavonoid biosynthesis were higher in Dacha, while pyrimidine metabolism was more prominent in Ercha. Several LAB species—including L. acetotolerans, Lentilactobacillus hilgardii, Lactobacillus amylovorus, and Lactobacillus amylolyticus—showed positive correlations with these flavonoids. Genes encoding L-lactate dehydrogenase and acetate kinase were mainly carried by L. acetotolerans and associated with acetic acid and ethyl acetate in fermented grains. These outcomes supported our hypothesis and suggested actionable levers for production: stage-targeted monitoring of marker taxa/genes and rational starter design to steer flavor formation in Fen-flavor Baijiu.

Hydrogen sulfide (H₂S) has been demonstrated to delay ripening and senescence in various fruits, offering great capability for postharvest preservation. However, existing application methods face several limitations, such as unstable release, difficulty in dosage control, and safety concerns, and its regulatory mechanisms in fruit systems remain unclear. In this study, calcium sulfide (CaS) was used as a slow-release H₂S donor that gradually releases H₂S through reactions with airborne moisture and carbon dioxide to treat bananas. CaS treatment significantly downregulated key ethylene biosynthetic genes and corresponding enzymes (ACO and ACS), thereby reducing ethylene production. The expression of starch-degrading and cell wall-modifying genes was also suppressed, delaying starch breakdown and cell wall disassembly. Enzyme assays and transcriptomic analyses confirmed that CaS delays banana ripening through coordinated regulation at both transcriptional and biochemical levels. As a result, CaS treatment effectively extended shelf life and maintained fruit quality of bananas. These findings reveal the potential of CaS as a novel H₂S-releasing agent for postharvest preservation.

Metabolite changes during the ripening process of cashew apples are crucial for their quality development. A total of 2379 metabolites were isolated and identified from fresh cashew apples at four different ripening stages using UHPLC-MS. Metabolite set enrichment analysis (MSEA) revealed that the differential metabolites in CA2_vs_CA1, CA3_vs_CA2, and CA4_vs_CA3 comparisons were mainly enriched in amino acids and peptides, steroids, pyrimidines, and fatty acids and conjugates, etc. Volcano plot analysis identified 631, 384, and 392 upregulated metabolites, and 625, 923, and 392 downregulated metabolites in CA2_vs_CA1, CA3_vs_CA2, and CA4_vs_CA3 comparisons, respectively. KEGG pathway enrichment analysis demonstrated that these differential metabolites were primarily involved in aminoacyl-tRNA biosynthesis, purine metabolism, and glycine, etc. Notably, the differential metabolites in CA4_vs_CA3 showed the highest enrichment in d-glutamine and D-glutamate metabolism, as well as phenylalanine. The metabolic profile of cashew apples revealed stage-specific patterns during ripening, offering key insights for optimizing harvest, storage, and processing.

Mustard greens are gaining global popularity, but preservation methods like salting and pickling raise specific concerns related to high sodium content and microbial safety. This study conducted a proteomics analysis to identify health-beneficial proteins in mustard greens.
Objective
To explore protein profiles associated with health benefits in fresh and preserved mustard greens.
Methods
Shotgun proteomics combined with LC-MS/MS was applied to identify proteins, followed by statistical analysis using Welch's t-test with Benjamini–Hochberg false discovery rate correction. Unique proteins were visualized with a Venn diagram, annotated using the Gene Ontology (GO) database, and mapped to functional categories with Sankey diagrams. In silico validation of protein stability and gastrointestinal digestion was performed to assess the release of bioactive peptides.
Results
A total of 118 high-confidence proteins were identified, including 27 unique to fresh, 23 to salted, and 22 to pickled mustard greens. Unique proteins in fresh mustard greens were associated with carbohydrate, amino acid, and nucleotide metabolism. Pickled mustard greens had proteins linked to carbohydrate, lipid, glycerol, vitamin, and cofactor metabolism, while salted mustard greens had proteins involved in amino acid, nucleotide, lipid, and glycerol metabolism. In silico digestion revealed that approximately 19–20 % of peptide fragments contained bioactive motifs, predominantly angiotensin-converting enzyme (ACE) and dipeptidyl peptidase-IV (DPP-IV) inhibitory sequences.
Conclusion
Preserved mustard greens contain unique proteins associated with health benefits based on GO annotations, distinguishing their protein profiles from fresh mustard greens. This study provides insights into their functional properties, addressing concerns related to their consumption.

Curcuminoids are the active compounds richest in turmeric rhizomes (Curcuma longa L.), comprising curcumin I, demethoxycurcumin (curcumin II), and bisdemethoxycurcumin (curcumin III). This study hypothesized that particular curcumin derivatives could mitigate oxidative stress and inflammation response by targeting specific inflammatory mediators. Therefore, this study aimed to quantify the concentrations of these curcuminoid forms in local turmeric extracts from Thailand. Subsequently, the study analyzed their in vitro antioxidant properties, alongside molecular docking and dynamics simulations targeting key oxidative stress- and inflammation-related proteins. Samples were collected from three representative cultivated areas in Thailand: the eastern, southern, and northern regions. The ethanolic extracts from all samples exhibited relatively high total curcuminoid content (eastern: 15.1 %, southern: 25.9 %, and northern: 31.6 % w/w in extract), as determined by high-performance liquid chromatography. Curcumin I emerged as the predominant variant, followed closely by curcumin II and III. The ethanolic extracts from the three cultural areas demonstrated significant antioxidant activity, as assessed by ORAC, FRAP, and DPPH assays. Among the three curcuminoids, curcumin III exhibited the strongest predicted binding affinities in molecular docking studies toward antioxidant and anti-inflammatory targets, including 5-LOX, NRF2, IKK1, NF-κB, and NOX4. Molecular dynamics simulations corroborated these findings, revealing that curcumin III formed the most stable complexes, particularly with IKK1, as indicated by low RMSD values (2–3 Å), and high hydrogen bond occupancy. Thus, curcumin III exhibits potential in silico inhibition of inflammatory mediators, supporting its promise as a natural compound for antioxidant and anti-inflammatory nutraceutical development.
姜黄素是姜黄根茎（Curcuma longa L.）中最丰富的活性化合物，包括姜黄素I、去甲氧基姜黄素（姜黄素II）和双去甲氧基姜黄素（姜黄素III）。本研究假设特定的姜黄素衍生物可以通过靶向特定的炎症介质来减轻氧化应激和炎症反应。因此，本研究旨在量化泰国当地姜黄提取物中这些姜黄素形式的浓度。随后，该研究分析了它们的体外抗氧化性能，以及针对关键氧化应激和炎症相关蛋白的分子对接和动力学模拟。样本采集自泰国三个具有代表性的种植区：东部、南部和北部地区。通过高效液相色谱法测定，所有样品的乙醇提取物均具有较高的姜黄素总含量（东部：15.1%，南部：25.9%，北部：31.6% w/w）。姜黄素I是主要的变体，其次是姜黄素II和III。通过ORAC、FRAP和DPPH检测，三个培养区的乙醇提取物显示出显著的抗氧化活性。在三种姜黄素中，姜黄素III在抗氧化和抗炎靶点（包括5-LOX、NRF2、IKK1、NF-κB和NOX4）的分子对接研究中表现出最强的预测结合亲和力。分子动力学模拟证实了这些发现，显示姜黄素III形成了最稳定的复合物，特别是与IKK1，正如低RMSD值（2-3 Å）和高氢键占用所表明的那样。因此，姜黄素III显示出对炎症介质的硅抑制潜力，支持其作为抗氧化和抗炎营养品开发的天然化合物的前景。

This pilot study explores the relationship between the genetic profiles of olive cultivars and monounsaturated fatty acid (MUFA) content of their oils, with emphasis on oxidative stability and phenolic integrity. Our working hypothesis was that cultivar-specific genetic variation in MUFA content, directly affects the oxidative stability of key phenolics, particularly oleocanthal and oleacein. To examine the association between genetic clustering and oleic acid content, eighty Greek olive cultivars cultivated under controlled nursery conditions were genotyped using eleven genomic simple sequence repeat (SSR) markers, and their fatty acid composition was determined by 1H NMR. Phenolic stability was tested using oils with contrasting MUFA levels. Genetic analysis identified three clusters. Chemical cluster analysis, by dividing cultivars into three MUFA classes, revealed significant differences among divisions. Linking genetic and lipid profile groups highlighted notable overlap. This study reveals a clear experimental association between MUFA abundance in the olive matrix and its capacity to preserve phenolic integrity. By confirming the role of MUFA content in phenolic stability, our results provide a baseline reference for early-stage cultivar selection and for future breeding programs targeting enhanced olive oil quality.

Our working hypothesis was that cultivar-specific genetic variation in MUFA content, directly affects the oxidative stability of key phenolics, particularly oleocanthal and oleacein. To examine the association between genetic clustering and oleic acid content, eighty Greek olive cultivars cultivated under controlled nursery conditions were genotyped using eleven genomic simple sequence repeat (SSR) markers, and their fatty acid composition was determined by <sup>1</sup>H NMR. Phenolic stability was tested using oils with contrasting MUFA levels. Genetic analysis identified three clusters. Chemical cluster analysis, by dividing cultivars into three MUFA classes, revealed significant differences among divisions. Linking genetic and lipid profile groups highlighted notable overlap.

To improve the quality and efficiency of cultivating Amomum tsaoko (AT), a non-model plant, it is crucial to understand the intrinsic molecular mechanisms underlying its growth. This review summarizes the significance of multi-omics in the study of plant molecular mechanisms and illustrates how multi-omics technology can solve the practical problems of non-model plants using AT as an example. In this review, we argue that nonlinear dimensionality reduction is more suitable for data organization in multi-omics because it is compatible with the nonlinear relationship between the components of systems biology. Subsequently, researchers have verified the strong vitality of multi-omics from three perspectives: the natural communication, breeding, and shade tolerance mechanisms of AT. Finally, we summarized some of the current commonly used plant genome databases and analyzed their utility for such research. We believe that our study makes a significant contribution to the literature because this review summarizes the multi-omics research process in detail, from data processing to application to the use of public databases, and illustrates the potential for the application of multi-omics with the example of a non-model plant, AT.

We hypothesized that the differences in meat quality stem from breed-specific regulation of muscle metabolic pathways. To explore the molecular mechanisms underlying meat quality differences between Liangshan cattle and Simmental crossbred cattle, we conducted metabolomic and transcriptomic analyses of the longissimus dorsi. Metabolomics revealed that Liangshan cattle exhibited higher l-carnitine levels, which may contribute to enhanced energy metabolism and improved meat quality, as well as a more favorable fatty acid composition. Integrated transcriptomic and metabolomic analysis suggested potential regulatory mechanisms: FASN may enhance fat deposition and tenderness by promoting butanoyl-CoA biosynthesis. Additionally, ALDOC, PFKL, PGAM1, and SDS may modulate citrulline metabolic flux, thereby influencing protein synthesis and promoting lipogenesis. These findings support our hypothesis by clarifying how coordinated gene–metabolite interactions influence meat quality. A potential regulatory model for the genetic-metabolic interaction of beef quality was established, providing a candidate framework for molecular breeding targeting beef quality traits.
