Recent studies have increasingly highlighted the importance of m⁶A modification in plant defense against viruses. In this investigation, we found that prunus necrotic ringspot virus (PNRSV) infection affected the m⁶A modification process. Plant transcriptomes and epitranscriptomes were sequenced to coanalyze the dynamic changes of m⁶A modifications after PNRSV infection. Further studies revealed that the silencing of evolutionarily conserved C-terminal region (ECTs), encoding m⁶A readers, led to increased PNRSV accumulation, indicating that ECTs confer resistance to PNRSV. Additionally, we demonstrated that <i>UPF3</i> and <i>SMG7</i>, which are involved in non-sense-mediated mRNA decay pathways, as well as phenylalanine ammonia-lyase (PAL), a well-known key enzyme in plant defense and an identified m⁶A-modified gene following PNRSV infection, play crucial roles in regulating PNRSV infection. These findings provide new insights into understanding PNRSV infection and further elucidate the role of m⁶A in modulating viral infection in plants.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"36 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902970","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}

This comprehensive review provides an analysis of the bioactive compounds in bananas, with a focus on the influence of varietal differences and ripening stages. Researchers have identified key bioactive molecules in bananas, including phenolic compounds, carotenoids, and biogenic amines, predominantly located in the banana peel. Unripe bananas contain higher levels of phenolic compounds and biogenic amines, whereas ripened bananas exhibit increased carotenoid content. Additionally, <i>in vivo</i> studies have indicated that flavonoids, particularly leucocyanidin, exert gastroprotective effects by enhancing gastric mucosal thickness and increasing epidermal growth factor receptor expression, which promotes angiogenesis and re-epithelialization of the gastric mucosa, thereby protecting against ulcer formation. The findings reinforce the medicinal value of bananas, particularly in their unripe state, and highlight the importance of further exploration into their bioactive components for the development of natural therapies targeting gastric health.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"280 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902971","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}

To gain deeper insights into how K regulates CA accumulation, we investigated CA synthesis in mitochondria, decomposition pathways, and vacuolar storage under both pot and field culture in Newhall navel orange (<i>Citrus sinensis</i>). Our findings demonstrated that an appropriate level of K enhanced CA concentrations primarily by modulating CA synthesis, as evidenced by the increased activities and gene expressions of citrate synthase (CS) and phosphoenolpyruvate carboxylase (PEPC) in the early stages of fruit development. Integration of mitochondrial proteomic and targeted metabolomic revealed that K promoted CA synthesis by accelerating the TCA cycle, which were supported by the upregulation of TCA cycle-associated proteins, including malate dehydrogenase, 2-oxoglutarate dehydrogenase E2 component, pyruvate dehydrogenase E2 component, and dihydrolipoamide dehydrogenase, along with elevated levels of TCA cycle-related metabolites such as CA, isocitrate, 2-oxoglutarate, and succinate. Additionally, K enhanced CA concentration in vacuoles by promoting vacuolar acidification, as evidenced by the upregulation of P-type ATPase (<i>CsPH8</i>) expression. In summary, our findings provide novel insights into K facilitating CA accumulation by modulating its synthesis and vacuole storage in Citrus.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"25 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898029","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}

A total of 174 ginger phenols and 235 ginger phenol dimers were annotated. Five new ginger phenols (<b>1–5</b>) and 18 known ginger phenols (<b>6–23</b>) were isolated following this proposed strategy, among which compound <b>1</b> was a new natural product and compounds <b>2–3</b> were novel ginger phenol dimers.

Enzyme-linked immunosorbent assay (ELISA) showed that compounds <b>2</b>, <b>18</b>, and <b>19</b> could significantly reduce the expression levels of cyclooxygenase-2 (COX-2) and interleukin-1β (IL-1β). In addition, compounds <b>2</b> and <b>18</b> displayed a certain inhibitory effect on the expressions of interleukin-10 (IL-10) and interleukin-6 (IL-6). The Western blot analysis revealed that compounds <b>18</b> and <b>19</b> effectively attenuated the expression of IL-1β, while only compound <b>2</b> inhibited the expression of phosphorylated nuclear factor kappa B (p-NF-κB) in BV2 cells.

Pot experiments demonstrated effective control of cucumber anthracnose at 0.2 μg/mL for bafilomycin C₁ and 0.4 μg/mL for JBIR-100, with efficacies reaching 78.5 and 67.7%, respectively.

IMI was below the limit of quantitation in plasma within 24 (1 mg/kg) and 48 h (10 mg/kg). At 10 mg/kg, IMI equivalents (sum of IMI and its metabolites) exceeded the regulatory threshold as established by the United States Code of Federal Regulations for pectoral and thigh muscle, brain, liver, spleen, kidney, fat, and eggs after 24 h. At 1 mg/kg, IMI equivalents surpassed the threshold for liver, spleen, and eggs after 24 h.

In this study, metabolomics based on UPLC-MS/MS was integrated with network pharmacology, molecular biology, and molecular docking to investigate the effects of Cin. The findings demonstrated that Cin markedly reduced mortality and lung bacterial load, lessened pulmonary damage while suppressing the levels of proinflammatory factors, including tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the bronchoalveolar lavage fluid (BALF) of infected mice. Additionally, 19 metabolites, primarily involved in tryptophan metabolism and arginine biosynthesis, were notably modified by Cin via suppressing the enzymatic activity of indoleamine 2, 3-dioxygenase 1 (IDO1) and inducible nitric oxide synthase (iNOS), thereby attenuating the inflammatory response. Notably, knockdown of IDO1 or iNOS significantly diminished the anti-inflammation effect of Cin. In conclusion, our study validates the therapeutic potential of Cin against <i>S. aureus</i> pneumonia via anti-inflammation by downregulating IDO1 and iNOS.

Using in vitro and in vivo models, we demonstrated that maltol upregulates RNF213, which inhibits the CDK14-Pdgfrβ signaling pathway, suppressing M1 polarization and reducing NFκB phosphorylation and pro-inflammatory cytokine production. Additionally, maltol decreases TNFSF12 secretion, mitigating estrogen deficiency-induced osteoblast apoptosis and promoting differentiation.
