Weed competition imposes both resource-based (abiotic) and allelopathic (biotic) stress, engaging overlapping hormonal pathways. This study examined the hormonal and transcriptomic mechanisms underlying multigenerational stress memory in wheat subjected to inter-specific competition with kochia and Italian ryegrass and intra-specific competition with other wheat plants. Phytohormone analysis revealed increased salicylic acid levels, promoting systemic acquired resistance, whereas jasmonic acid levels declined, indicating suppressed jasmonate-mediated defence. Abscisic acid responses varied, reflecting shifts in water-use efficiency. Cytokinins and auxins exhibited generation- and treatment-specific trends, suggesting adaptive resource acquisition but potential hormonal imbalances. These hormonal shifts corresponded with phenotypic responses, where adaptive benefits peaked at Generation 3 before transitioning to maladaptive responses in later generations. Transcriptomic analysis identified dynamic changes in differentially expressed genes (DEGs) and key pathways. Wheat-only competition peaked in stress-responsive DEGs in Generation 3, while wheat-kochia and wheat-ryegrass exhibited early generation transcriptional reprogramming and long-term adaptations. Intra-specific wheat competition showed early generation transcriptomic surges but persistent growth repression in the current study. These findings provide mechanistic insights into multigenerational stress memory mechanisms and reveal how phytohormonal crosstalk and transcriptional reprogramming shape wheat responses to competition stress across generations.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"3436-3454"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13136550/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147429795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a negative single-stranded RNA virus, tomato spotted wilt orthotospovirus (TSWV) which is a representative member of genus Orthotospovirus in the Tospoviridae family, was used as a model to investigate the mechanisms involving the interaction between the viral and the host plant proteins in vesicle formation and function. We found that the nonstructural protein (NSm) of TSWV, could induce endoplasmic reticulum (ER)-derived pathological vesicle biogenesis. In addition, NSm might hijack the host immunity proteins, NtPOX1 (a peroxidase) and pathogenesis-related protein NtPR-4A, to form a potential tetrameric protein complex with Sar1 (a small GTPase), which was crucial for NSm-induced vesicle biogenesis. The results also showed that these ER-derived pathological vesicles provided sites for TSWV replication.

The levels of m6A are determined by the coordinated actions of methyltransferases ('writers') and demethylases ('erasers') that introduce and remove m6A marks, respectively. Recent studies have demonstrated that chloroplast mRNAs are highly rich in m6A; however, the significance of m6A methylation in chloroplasts remains unknown. As no mRNA m6A writers and erasers have been identified in chloroplasts, in this study, we artificially imported ALKBH10B, a well-characterised mRNA m6A eraser localised in the nucleus and cytoplasm in Arabidopsis (Arabidopsis thaliana), into chloroplasts to uncover the potential impact of m6A modification in chloroplasts on photosynthesis and abiotic stress response. We found that the chloroplast-targeted ALKBH10B successfully removes m6A marks from numerous mRNAs in chloroplasts. Notably, the ALKBH10B-mediated demethylation f m6A marks in chloroplast mRNAs enhanced salt and drought tolerance in Arabidopsis by modulating the stability of m6A-modified photosynthesis-associated mRNAs. Overall, our findings reveal that ALKBH10B-mediated m6A demethylation in chloroplast mRNAs enhances photosynthesis and stress tolerance, highlighting that modulation of RNA methylation in chloroplasts can be a potential means for breeding stress-tolerant plants.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"3306-3323"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147300408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we systematically screened 28 Clonostachys spp. strains for biocontrol efficacy against FCR and identified Clonostachys chloroleuca strain Cc620 as a highly promising agent. Cc620 exhibited strong mycoparasitic activity against Fusarium pathogens and functioned as an endophyte primarily colonizing wheat roots. Seed treatment with Cc620 significantly promoted wheat seed germination, root development, and enhanced resistance to both FCR and FHB under greenhouse and multi-location field conditions. Furthermore, the Cc620 application improved agronomic traits of wheat in fields and suppressed a broad spectrum of wheat and soybean diseases. Genomic and transcriptomic analyses revealed that Cc620 induces extensive metabolic reprogramming and upregulates defense-related pathways in wheat, including key immune regulators such as TaWRKY33. Moderate overexpression of TaWRKY33 in wheat conferred increased resistance to both FCR and FHB without a yield penalty. Field surveys confirmed the natural occurrence and strong colonization potential of C. chloroleuca in major wheat-growing regions. Our findings demonstrate that Cc620 is a robust and sustainable biocontrol agent, offering a promising alternative for integrated disease management in wheat production.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"3254-3271"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147281283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study characterises Burkholderia arboris M13, a novel biocontrol strain exhibiting broad-spectrum antagonism in vitro against major phytopathogenic bacteria of horticultural crops, including Pseudomonas syringae pv. tomato, Ralstonia solanacearum, Paracidovorax citrulli, and Xanthomonas campestris pv. campestris. Applications of its bacterial suspension or culture supernatant significantly suppressed tomato bacterial speck, bacterial wilt, watermelon bacterial fruit blotch, and cabbage black rot in greenhouse and field trials. The strain also induced plant systemic resistance and promoted plant growth. Genomic analysis revealed significant novelty, as B. arboris M13 possesses two unique plasmids and harbours 20 biosynthetic gene clusters for secondary metabolites, with several showing weak collinearity to close relatives, indicating genetic determinants for its expanded functionality. Furthermore, B. arboris M13 demonstrated compatibility with the plant growth regulator (24-epibrassinolide) but incompatibility with the copper-based bactericide copper hydroxide, which enhances its practical integration into existing crop management strategies. This combination of effective biocontrol, plant growth promotion, distinct genomic features, and chemical compatibility establishes B. arboris M13 as a versatile and promising candidate for sustainable agriculture.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"3204-3222"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147275314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light-driven photosynthesis model, parameterised with empirical data, with functional growth analyses to estimate the C costs and amortisation times of upper, sun exposed and lower, shaded branches in the crowns of mature trees from nine European species in a diverse and relatively open mixed forest. Amortisation times for the C costs of 1-year-old branches varied among species, but not between sun and shade branches except for two species. Expressed as percentage of the branch C uptake, branch costs were similar between crown positions in most species. Finally, a similar proportion of C assimilation is used for the seasonal build-up of starch in upper and lower branches. Our results show that, at least in forests with relatively open canopies as the one studied here, the balance of assimilation and structural and non-structural C costs at the branch-level is finely tuned along the light gradient, suggesting a high degree of C autonomy even in shaded branches.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"3351-3362"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13136552/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147352938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
