Our study focused on vesicles from species in the non-model plant group, Pinus (pine) (P. elliottii, P. radiata, and P. patula × Pinus tec (hybrid)). These plants have tougher tissues and strong, acicular-shaped leaves (needles). Herein, we first developed a protocol to guide effective collection of juice fluid from needles and roots in a clean and efficient manner. The effects of these vesicles were characterized in terms of the global nutrient profile of the pine pitch canker fungus, Fusarium circinatum, generated from growing fungal spores on ~400 substrates embedded across BioLog phenotypic microarray (PM) plates (PM1, PM2A: carbon sources; PM3B: nitrogen sources; PM9: osmolytes/pH; PM24C: chemicals). Our findings revealed that MVs, specifically needle-derived MVs (ndMVs) from P. elliottii, disrupt metabolite assimilation in several important pathways, including carbon and nitrogen metabolism. The PM data were also strongly correlated with observed phenotypic effects, including reduced viability and germination of spores in liquid media, as well as impaired filamentous growth on solid media. Importantly, these MV-induced phenotypic effects were reproducible in other filamentous pathogens (e.g., Botrytis cinerea, Chrysoporthe cubensis and F. graminearum) and during a glasshouse trial conducted with F. circinatum-infected P. elliottii seedlings, demonstrating the stable biological effects of ndMVs. Cumulatively, our results suggest that plant-derived vesicles can disrupt metabolism in pathogenic fungi and, therefore, serve as a cost-effective and sustainable source of novel plant protection molecules.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144566867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant scientists now pay more attention to generating pepper cultivars that offer both increased yield and richness in these crucial ingredients. Indeed, the average pepper yield per hectare, as well as richness of these ingredients, are affected by multiple environmental stimuli. However, expression of specific genes is crucial to stimulate the CAT and CAP levels in response to environmental conditions. Recently, new technologies, like genome editing using CRISPR/Cas and engineering of chloroplasts, have been tested in chilli pepper. The advances in genome editing tools, such as the prime editor and base editor methods, have tremendous potential for plant organelle genome engineering. In this article, we highlight recent advancements in CRISPR/Cas and plastid engineering within Capsicum, coupled with application of base editing approaches for editing plant organelle DNA. We also assess the challenges and opportunities in the pursuit of commercial and sustainable production of bioactive compounds specific to Capsicum species.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Susceptibility of plants to biotrophic and hemibiotrophic infections are mostly enhanced by short-term heat shock (HS), but little is known about HS effects on plants infected by necrotrophic pathogens. Here we evaluated the effects of HS in susceptible barley (Hordeum vulgare cvs. Ingrid and Himalaya) infected with the necrotrophic Pyrenophora teres f. teres (Ptt) by monitoring disease symptoms, Ptt biomass, plant defence components (ROS, antioxidants and defence-related gene expression). Ptt biomass was assessed by qPCR, hydrogen peroxide (H2O2) levels using DAB histochemical staining, enzyme activities and glutathione levels with spectrophotometric methods, and gene expression using reverse transcription qPCR. HS suppressed defence responses to Ptt in both barley cultivars, resulting in increased necrotization and fungal biomass. HS-induced enhanced susceptibility was accompanied by significant increases in H2O2 production. Activities of GR and GST enzymes were induced by Ptt inoculation in both cultivars, but HS further elevated GST activity only in cv. Ingrid. Glutathione concentrations increased in cv. Ingrid due to combined effects of HS and Ptt inoculation. Expression of HvPR-1b encoding pathogenesis-related (PR) protein-1b increased primarily in response to Ptt infection; however, HS-treated plants had higher transcript levels along with enhanced susceptibility. HS induces enhanced susceptibility of barley to Ptt, associated with elevated ROS levels and expression of plant defence-related genes encoding antioxidants and PR-1b. Our results contribute to elucidating the influence of HS on barley defence responses to necrotrophic pathogens.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
