However, the molecular mechanisms underlying root elongation in rice ( Oryza sativa ) remain unclear. Here, we identified a short root mutant, short root‐31 ( sr31 ), and cloned the causal gene by map‐based cloning, which carries a point mutation in the coding sequence of DYNAMIN‐RELATED PROTEIN 1C ( OsDRP1C ). Genetic complementation analyses demonstrated that OsDRP1C is responsible for the phenotypic defect of sr31 . OsDRP1C is widely expressed in roots, with higher expression in root meristem, epidermal cells and vascular bundles. Colocalization analysis revealed that OsDRP1C is present in the plasma membrane (PM) and endomembrane system. FM4‐64 internalization assay showed that endocytosis is inhibited in sr31 . Further study indicated that OsDRP1D and OsDRP1E are also involved in root elongation; OsDRP1C interacts directly with OsDRP1D/E, and they function additively on root elongation. Furthermore, we showed that the trafficking and recycling of OsPIN1b between endomembrane and PM localization are attenuated in sr31 , which affects auxin polar transport. These results provided the first insights into the molecular mechanism of OsDRP1C modulating OsPIN1b cycling in regulating root elongation, expanded our understanding of OsDRP1s' association with membrane protein trafficking in rice.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"24 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090435","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 tested whether petal light transmission and internal floral temperature influence microbial abundance in two co‐occurring species, Lyonia lucida and Lyonia fruticosa (Ericaceae), which have translucent petal ‘windows’ that modify internal light environments. We measured internal and external floral temperatures, quantified culturable microbial abundance (yeasts, molds, bacteria), and assessed ultraviolet (UV) and infrared (IR) petal transmission using spectrometry. We then experimentally tested the UV resistance of microbial communities across 108 flowers from 18 plants. Additionally, we used manipulative light experiments to test whether IR radiation drove differences in floral warming between these two species. Petal windows transmitted more UV and IR radiation than pigmented tissue. Internal floral temperature predicted microbial abundance, with warmer flowers harboring fewer microbes. A spectral filter experiment confirmed that IR radiation warms L. lucida flowers but not L. fruticosa , while natural variation in UV transmission did not predict microbial abundance or UV resistance. Petal spectral traits shape floral microclimate and microbial abundance primarily through temperature‐mediated filtering linked to IR‐driven warming rather than passive UV sterilization. These results position flowers as microhabitats where petal traits constrain microbial communities.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"147 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090436","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 describe here a comprehensive multi‐omics analysis of the apoplastic washing fluids content just 6 h after the onset of Arabidopsis thaliana infection with Botrytis cinerea , a fast‐killing necrotrophic fungus. By varying plant nitrogen nutrition, known to affect both plant defenses and pathogen virulence, we identify candidates that do not stand out under optimal conditions.

Although hormesis – stimulatory responses to low doses of otherwise toxic compounds – has been documented following herbicide exposure, it has rarely been examined within an evolutionary ecology framework. Here, we examine herbicide‐induced hormesis in the agricultural weed Oxalis stricta across two field experiments. We exposed replicated maternal lines to dicamba drift and quantified growth, reproductive traits, floral allocation, and pollinator visitation. Dicamba drift consistently increased flower production in both years, revealing a plastic shift toward reproductive allocation. Fitness consequences were context‐dependent: in 2022, increased flowering was associated with higher seed production through indirect, trait‐mediated pathways, whereas in 2023, increased flowering did not translate into detectable differences in reproductive output. We detected little genetic variation in hormetic responses, suggesting limited potential for adaptive evolution. Dicamba drift also reduced individual flower size, indicating a shift toward larger floral displays composed of smaller flowers. These allocation shifts reduced pollinator visitation primarily through changes in flower number, linking herbicide exposure to trait‐mediated changes in plant–pollinator interactions. Together, our results show that low‐dose herbicide exposure can generate compensatory responses that reshape ecological interactions, even when evolutionary responses are constrained.

Pore aperture adjustment is a mechanical process whereby changes in guard cell turgor drive changes in cell shape, resulting in stomatal opening or closure. Previous computational models of kidney‐shaped stomata primarily relied on guard cells elongating upon turgor increase, a process dependent on cell wall properties, such as anisotropy in stiffness, strain‐stiffening, and polar fixing. Finite element method simulations using experimentally derived 3D meshes from confocal imaging of Allium cepa (onion) suggest an alternative mechanism for opening that is largely due to changes in guard cell cross‐sectional shape. This mechanism does not rely on the assumptions for cell wall parameters required in previous models based on idealised geometries. We propose that mechanical responsiveness of guard cells to turgor changes is determined by a combination of two processes: one dependent on shape and the other on wall material properties. This suggests the parameters governing guard cell dynamics can be viewed abstractly as a two‐dimensional (shape and material properties) ‘morphospace’, allowing multiple routes of shape adaptation to optimise gas exchange.

Their long‐term evolutionary interactions led to mutual adaptation, creating a complex ecological symbiosis. However, the deep‐time ecological associations of mimicry between insects and plants remain limited due to the scarcity of preserved fossils. Here, we report the fossil evidences of mimicry between praying mantis and spike mosses in 98‐Myr‐old Kachin amber. The new Cretaceous mantis, Folimantis hyalinala gen. et sp. nov., has a rare form of leaf mimicry via abdominal leaf‐shaped extensions that resemble contemporaneous vegetative leaves (trophophylls) of Selaginella in shape, size, and pattern of arrangement. The new findings provide the earliest direct evidence of the co‐associations between mantis and its mimetic plants during the Cretaceous and suggest that the stem‐group had already developed distinct structural features that mimic plant leaves during the early divergences of Mantodea. A diversification analysis of mimicry between fossil insects and plants from the Late Paleozoic and Mesozoic indicates that, before the rise of angiosperms in the Late Cretaceous, mimicry between insects and gymnosperms, ferns, lichens, and even Selaginella had existed for a long time and that changes in mimicry forms paralleled the evolutionary succession of plant lineages.

However, the molecular mechanisms and functions of effectors to achieve this remain poorly understood. Using fluorescent and transmission electron microscopy of P. brassicae ‐infected Arabidopsis, we show that host endomembranes and organelles become closely associated with P. brassicae secondary plasmodial structures and are subsequently phagocytosed by the pathogen. PbALE is a secreted endomembrane‐targeting effector that binds a range of phospholipids. Overexpression of the effector results in plants with glossy leaves that progressively become chlorotic. Fluorescent protein‐tagged PbALE is observed in large condensates that cluster with plant organelles, disrupting endocytic recycling of plant membrane receptors and immune regulatory proteins, thereby impairing penetration resistance to nonadapted barley powdery mildew infection. PbALE's association with the P. brassicae plasmodial surface and the extrahaustorial membrane during adaptive powdery mildew infection, along with the recruitment of PI(4,5)P 2 to these membrane contacts, supports a model in which the effector nucleates lipid‐rich compartments and enriches organelles at the host‐pathogen interface. Our findings reveal a lipid‐binding effector that remodels host endomembranes, disrupts immune trafficking, and aids pathogen colonization, offering insights into strategies for durable disease resistance.

Although its activity depends on transmembrane transport, the transporter of DKC remains unknown. Using transcriptome profiling and a yeast expression system, OsPDR17, an ABCG transporter, was identified and functionally characterized as the major DKC transporter. Its role during Xanthomonas oryzae pv oryzae infection was examined via CRISPR/Cas9 and overexpression, and a transcription factor regulating OsPDR17 was identified. OsPDR17 was localized to the chloroplast membrane, and key enzymes for DKC biosynthesis were chloroplast‐localized proteins. OsPDR17 knockout significantly suppressed the expression of DKC biosynthetic genes, reduced DKC accumulation, and weakened resistance to bacterial blight, whereas overexpression of OsPDR17 showed opposite effects. Notably, we revealed that residue D1149 was essential for OsPDR17‐DKC the interaction using molecular docking and site‐directed mutagenesis analysis. In addition, WRKY10, a known transcription factor of DKC biosynthetic genes, was found to be potentially involved in regulating OsPDR17 expression. Taken together, this work uncovered the pivotal function of OsPDR17 in rice resistance to bacterial blight, mediating the transport of phytoalexin DKC and orchestrating feedback regulation of DKC biosynthesis. These results offered a theoretical insight and an important genetic resource for rice disease resistance research.
