Expansin-like proteins have been implicated in cell wall dynamics and metal binding; however, their in planta role in As detoxification remains unexplored. This study reveals a pivotal role for the rice expansin-like protein OsELP in As compartmentalisation and tolerance. Using transgenic approaches in Arabidopsis thaliana and rice, we showed that OsELP overexpression significantly enhanced tolerance to both arsenite and arsenate stress, protecting biomass and photosynthetic efficiency. Mechanistically, OsELP facilitated the apoplastic sequestration of As in roots, as visualised by Scanning Electron Microscopy-Energy Dispersive x-ray spectroscopy (SEM-EDX) imaging. This sequestration acted as a root filter, increasing root As retention and reducing shoot translocation, which culminated in a significant reduction of As in grains in the overexpression lines. This spatial restriction of As mitigated oxidative and photosynthetic damage by enhancing antioxidant enzyme activities and limiting reactive oxygen species accumulation. In contrast, the Oselp knockout line exhibited increased As accumulation in aerial tissues and heightened sensitivity.

Fluorometric analysis confirmed phytoalexin deficient3 (PAD3) as an HCN synthase, with significantly elevated HCN levels in OE-PAD3 and reduced levels in the pad3 mutant. Subsequent experiments revealed that under salt stress, H₂S enhanced ROS scavenging while HCN promoted accumulation, with the pad3 + H₂S treatment showing significantly improved salt tolerance.

Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si-mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and pathogen and is altered by environmental factors. We performed a meta-analysis to quantitatively assess the benefits of Si fertilisation for improving disease resistance against fungal pathogens in grasses. Overall, Si fertilisation decreased disease severity by 43% and increased biomass of infected plants by 35%. The underlying mechanisms were investigated by analysing the impacts of Si against diverse fungal infection strategies. The disease suppressive effect of Si was greater for pathogens producing appressoria, a structure involved in cell wall penetration and effector release, but lower against pathogens entering through stomata. Furthermore, Si was more effective against pathogens that produce haustoria or infection hyphae, which are involved in nutrient acquisition. These findings advance knowledge of plant-pathogen interactions by identifying key pathogen traits determining Si effectiveness against pathogen attack in grasses. Our results support using Si fertiliser for cereal crops to reduce fungal damage and suggest Si should be considered in studies of grass evolutionary history and community structure.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831420","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}

Plant stomata serve as portals for water transpiration and gas exchange, where adjustments in stomatal aperture critically influence drought resistance in trees. Although guard cell actin cytoskeleton dynamics are essential for stomatal movement, their regulation in trees remains poorly understood. This study characterises PuCIPK11 in Populus ussuriensis Kom., demonstrating its role in enhancing drought resistance via stomatal closure. PuCIPK11 predominantly expressed in guard cells and induced by drought and ABA, and its overexpression promotes microfilaments (MFs) depolymerisation and longitudinal rearrangement, accelerating stomatal closure. Under drought stress, PuCIPK11 is recruited to the plasma membrane by the Ca²⁺ sensor PuCBL9, where it undergoes conformational activation through the formation of a PuCBL9-PuCIPK11 module. Furthermore, PuCIPK11 phosphorylates PuCBL9 at Ser201, a process enhanced by ABA that strengthens their interaction. Functional validation using pucbl9 knockout mutants in a PuCIPK11-overexpression background confirmed that PuCIPK11 acts in concert with PuCBL9 to modulate MFs dynamics and drought tolerance.

Cutinase Transcription Factor 1 (Ctf1) facilitates degradation of the plant cuticle, as well as early infection and colonisation; however, the transcriptional regulation and pathogenic mechanisms of the Ctf1β subfamily remain unclear. We found that the ApCtf1β family contains conserved core domains and variable terminal regions. Through synteny analysis combined with interaction transcriptomics, we identified ApCtf1β2 as a key pathogenicity gene that is significantly upregulated during infection. Functional analyses revealed that ApCtf1β2 is involved in fatty acid metabolism, stress responses, and sporulation, and that ΔApCtf1β2 significantly reduces virulence. Integrated CUT&Tag and RNA-seq analyses identified ApCUT3 as a primary target; Yeast One-Hybrid (Y1H), Electrophoretic Mobility Shift Assay (EMSA), and Dual luciferase assay (DLR) confirmed that ApCtf1β2 directly activates ApCUT3 expression by binding to the GCC(n5)CGG motif in the ApCUT3 promoter. ApCUT3, a secreted cutinase, possesses a functional signal peptide, localises to extranuclear compartments, and plays a pivotal role in degrading the host cuticle. Single-gene knockouts (ΔApCtf1β2 or ΔApCUT3) each attenuate pathogenicity, whereas the double knockout (ΔApCtf1β2/ApCUT3) exhibits a pronounced hypovirulent phenotype with synergistic interaction. Hosts infected with the double mutant maintain relatively intact cuticles, exhibit substantially weakened JA and SA defence signalling, and display markedly reduced defence enzyme activities. In summary, the ApCtf1β2-ApCUT3 module promotes fungal infection by transcriptionally activating ApCUT3, a key cutin-degrading enzyme, thereby compromising the host physical barrier and indirectly modulating host defence responses through Damage-Associated Molecular Patterns (DAMPs) release. These findings provide a theoretical basis for targeted control of fungal diseases.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831570","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}

However, the regulation of PUFA homoeostasis remains poorly understood. Direct molecular and genetic evidence linking specific FA desaturation enzymes to this process is limited. Here, we investigated two soybean FA desaturation genes, GmROD1a/b, and provided their previously unrecognised roles in nodulation. Both were strongly induced during early rhizobial infection and remained highly expressed throughout nodule development. Overexpression significantly enhanced nodulation and plant growth, whereas disruption reduced nodule numbers. Transcriptomic analyses further revealed that GmROD1s promote PUFA accumulation and regulate genes associated with nodulation and nodule function, energy metabolism, membrane biogenesis, etc. We also identified two members of the WRINKLED family of transcription factors that are co-expressed with GmROD1 in rhizobia-infected roots and nodules. Further, promoter binding and transcription activation assays confirmed that GmWRI1 and the newly identified nodulation-associated factor, GmWRI3, directly promote GmROD1a/b expression, and overexpression of either transcription factor in soybean hairy roots significantly promoted nodulation. Together, our study uncovers a previously unappreciated role of ROD1 in nodulation, extending the functional role beyond FA desaturation. More importantly, we provide new molecular evidence linking nodulation to PUFA biosynthesis mediated by a previously unappreciated GmWRI1/3-GmROD1a/b regulatory module.

We demonstrate that the Bacillus amyloliquefaciens SN16-1 exhibits antagonistic activity against M. oryzae Guy11.
