Their biomass is often limited by iron (Fe) in most ocean waters and is widely affected by global warming. However, the interactive effect of warming and Fe limitation on diatoms has not yet been revealed. Here, we found that Fe limitation inhibited the growth of Phaeodactylum tricornutum, but this inhibition could be alleviated by warming. Fe limitation combined with warming affected most metabolic pathways, including ribosomes, Fe acquisition, photosynthesis and respiration. However, the strategies of P. tricornutum response to warming varied across different temperature ranges under Fe limitation. Under Fe limitation, P. tricornutum enhances catabolism via upregulating the proteolytic pathway while suppressing ribosome biosynthesis/assembly when the temperature is elevated from sub-Topt to Topt, but conversely upregulates the ribosome biosynthesis/assembly and suppresses the catabolism pathways when the temperature is elevated from Topt to super-Topt. These findings revealed that the varied mechanisms of marine diatoms' response to the interaction of Fe limitation and warming depended on the difference between the habitat temperature and their optimal temperatures. Our results provide new insights into the changing trends in diatoms' responses to global warming in Fe-limited regions, with significant implications for ocean productivity and marine biogeochemical cycles in a future changing climate.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184344","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}

While plant defence mechanisms against B. cinerea are well-studied, its epigenetic regulation remains largely unknown. DRM2-mediated de novo DNA methylation plays pivotal roles in plant development and stress adaptation, yet its contribution to tomato resistance against fungal pathogens remains largely unclear. In this study, we show that tomato with lower global DNA methylation levels exhibit stronger resistance to B. cinerea, revealing a key contribution of epigenetic regulation to plant immunity. To determine the role of DRM2 in tomato defence against B. cinerea, we conducted an integrative multi-omics analysis. Further investigation revealed that overexpression of DRM2 promoted jasmonic acid (JA) accumulation and activated the JA-mediated signalling pathway, thereby enhancing tomato resistance to B. cinerea. Particularly, DRM2 was shown to bind the promoter of AOS, a key gene in JA biosynthesis, modulating its epigenetic state. Overall, this study uncovers the epigenetic mechanisms governing plant defence against B. cinerea and identifies a promising candidate gene for breeding tomatoes with enhanced disease resistance.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147229","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}

We used shotgun metagenomics to examine microbial taxonomic and functional colonisation patterns in wild populations of the pan-palaeotropical C4 grass, Themeda triandra, across a globally representative aridity gradient (aridity index 0.318-0.903). We investigated these patterns through the two-step selection process whereby microbes are recruited from bulk soils into rhizospheres (soil on the root surface), and root interiors (endospheres). We provide clear evidence of this process through decreasing microbial taxonomic diversity from bulk soil to T. triandra roots. Surprisingly, microbial functional potential showed the opposite trend: the diversity of potential functions (exponent of Shannon's diversity) increased from bulk soil to the rhizosphere and endosphere, but functional richness did not. Finally, we found that increasing aridity was associated with rhizospheres that were more compositionally similar, yet remained highly diverse in functional potential. Overall, aridity is strongly associated with the root-associated microbiome of T. triandra, selecting for microbiota that likely support plant resilience under dry conditions. Furthermore, microbial functional potential closely tracks taxonomic composition and aridity trends, highlighting how native plants can shape their microbial communities.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147141","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}

While ethylene and abscisic acid (ABA) are known to synergistically regulate anthocyanin biosynthesis via transcription factors (TFs) in plants, their regulatory roles in M. 'Profusion' under rust stress remain elusive. In this study, we found that the release of ABA and ethylene significantly increased during rust infection. Crucially, we identified MpbZIP46, a novel ABA-responsive bZIP TF, as playing a key role in anthocyanin biosynthesis. Overexpression of MpbZIP46 significantly promoted anthocyanin synthesis, while CRISPR/Cas9-mediated knockdown of MpbZIP46 significantly reduced anthocyanin content. Further studies showed that under rust conditions, the release of ABA and ethylene synergistically promoted the accumulation of anthocyanins in M. 'Profusion' rust spots. Mechanistically, MpbZIP46 physically interacts with the ethylene-responsive TF MpERF105, forming a functional complex that synergistically transactivates the promoter of MpMYB10b-the core regulator of anthocyanin synthesis, thereby driving anthocyanin production in rust-stressed leaves. In conclusion, this study established the molecular mechanism by which ABA and ethylene regulate anthocyanin synthesis in M.

Plants develop a plethora of responses to improve phosphate acquisition, known as phosphate starvation responses (PSR). Among them, the induction of phosphoenolpyruvate carboxylase (PEPC) has been described in many plants. However, most studies have been conducted in the absence of phosphate, thus the real impact of PEPC in PSR is missing as there is no phosphate to take up. In this study, we used modified sorghum plants silenced in the main PEPC isozyme in roots, SbPPC3, and analyzed the role of PEPC in the presence of insoluble calcium phosphate (PCa), showing a phosphate starvation phenotype in silenced but not in WT plants. Interestingly, root exudation of citrate was not reduced in silenced plants, probably due to a higher citrate synthase activity, but it was reduced for succinate, another compound with phosphate solubilisation capacity. Finally, silenced plants accumulated less P in roots with PCa, leading to a reduced phosphate acquisition efficiency (PAE). Our results show, for the first time, the actual role of PEPC in phosphate solubilisation through succinate exudation, proposing PPC3 as a specific target to improve PAE in plants.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136172","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}

Although Trichoderma koningiopsis improves damping-off disease resistance in Masson pine by regulating the rhizosphere microbial community, the underlying mechanisms remain unknown. Metabolomic analysis showed that T. koningiopsis altered Masson pine root exudates, especially plant organic acids such as capric acid (CA), lauric acid (LA) and pelargonic acid (PA). Co-culturing rhizosphere microbes with 0.1 mM CA, LA, PA and a combination of the three (1:1:1, CDNs1) significantly inhibited F. oxysporum and promoted the growth of rhizosphere biocontrol strains (Trichoderma, Penicillium and Bacillus), with CDNs1 exerting a superior effect. Amplicon sequencing and RT-qPCR showed that CDNs1 significantly altered the microbial community composition in the rhizosphere, especially inhibited the growth of Fusarium and enriched beneficial microbes (Trichoderma and Penicillium). CDNs1 effectively decreased the incidence and severity index of damping-off disease in Masson pine seedlings by 73.33% and 41.67%, respectively. Mechanistically, CDNs1 enhanced resistance to damping-off disease by modulating plant hormones, oxidative stress defences and the photosynthesis pathway.
