{"title":"The class VIII myosin ATM2 stabilizes actin–plasma membrane contacts in tobacco pollen tubes by locally promoting PtdIns(4,5)P2 formation","authors":"Vera C. Wagner, Marta Fratini, Johanna Uhlenberg, Alexandra Schutkowski, Gottfried Hamm, Christoph Kastner, Kirsten Bacia, Kateřina Schwarzerová, Ingo Heilmann","doi":"10.1038/s41477-026-02427-0","DOIUrl":"10.1038/s41477-026-02427-0","url":null,"abstract":"The intersection of actin filaments with the plasma membrane (PM) in plant cells involves lipid–protein interactions by the Arabidopsis class VIII myosin ATM2 that are currently not understood. Using pollen tube cells as a model, we describe how ATM2 enables actin–PM contacts by modulating membrane lipid nano-organization. ATM2 bound anionic PM lipids, including phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2), with no apparent preference for any particular lipid species. Overexpression of ATM2 unexpectedly stabilized actin dynamics and altered pollen tube morphology. Actin dynamics remained unaltered upon overexpression of a lipid-binding-defective ATM2 variant. ATM2 effects on actin dynamics required PtdIns(4,5)P2, as artificial PtdIns(4,5)P2 depletion in pollen tubes abolished the effects of full-length ATM2 on actin dynamics despite its retained PM association. ATM2 colocalized and interacted with the PI4P 5-kinase PIP5K2, which resides at actin–PM contacts and forms PtdIns(4,5)P2 nanodomains facilitating rho-of-plants-dependent actin stabilization. Upon ATM2 overexpression, a fluorescent PtdIns(4,5)P2 biosensor decorated an extended PM region in vivo, indicating a promoting effect of ATM2 on PtdIns(4,5)P2 abundance. The catalytic activity of purified recombinant PIP5K2 protein was enhanced upon coincubation with a purified carboxy-terminal ATM2 fragment in vitro, suggesting that ATM2 contributes to the intrinsic regulation of PtdIns(4,5)P2 formation. Actin dynamics are thus stabilized at the actin–PM interface by ATM2 locally promoting the formation of PtdIns(4,5)P2 nanodomains, thereby self-reinforcing ATM2 recruitment while also facilitating rho of plants activation to stabilize membrane-proximal actin filaments. The Arabidopsis class VIII myosin ATM2 enables actin–plasma membrane contacts by locally promoting PtdIns(4,5)P2 formation. The modulation of plasma membrane lipids self-reinforces ATM2 recruitment and stabilizes membrane-proximal actin dynamics.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"2089-2107"},"PeriodicalIF":15.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41477-026-02427-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207510","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}

Current chromatin conformation capture (3C)-based haplotype-resolved scaffolding methods often produce highly incomplete and mis-phased assemblies of complex polyploids, as short sequences lacking sufficient interaction support and collapsed regions with misleading signals are difficult to resolve. Here we present GPhase, a haplotype-resolved scaffolding algorithm that integrates 3C (for example, Hi-C, Pore-C and Omni-C) data with assembly graphs to enhance accuracy, completeness and contiguity. By leveraging graph connectivity derived from long-read overlaps, GPhase effectively overcomes key limitations of 3C. When applied to 15 complex polyploid genomes, GPhase reduced the sequence missing rate (BUSCO-based) by up to tens-fold, decreased the sequence error rate (k-mer-based) by up to an order of magnitude and improved the contiguity (N50) of gap-free sequences by several-fold compared with existing tools. This study presents GPhase, a haplotype-resolved scaffolding algorithm that leverages assembly graphs to overcome key limitations of 3C data and substantially improve the accuracy, completeness and contiguity of complex polyploid genome assembly.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"1960-1975"},"PeriodicalIF":15.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41477-026-02422-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207458","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}

{"title":"Extreme greenhouse warmth triggered the two major floristic turnover events of the past 120 million years","authors":"J. M. Kale Sniderman, Gregory J. Jordan, Chris Mays","doi":"10.1038/s41477-026-02429-y","DOIUrl":"10.1038/s41477-026-02429-y","url":null,"abstract":"Over the past 120 million years, flowering plants (angiosperms) became ecologically dominant in most terrestrial biomes, displacing other land plants. However, this spectacular transition was delayed until the early Cenozoic, tens of millions of years after major angiosperm groups emerged. One suggested trigger for the transition is the extreme warmth of early Cenozoic climates, but there are perceptions that important steps in angiosperm evolution also occurred under cool climates. To evaluate how angiosperms and other land plants responded to past climates, we implemented sampling-standardized analyses of compilations of spore–pollen fossil records from high and low palaeolatitudes. Here we show that floristic turnover (elevated rates of first and last appearances) of all land plant groups was concentrated within brief mid-Cretaceous and early Cenozoic episodes of extreme global warmth, synchronized across high and low latitudes. Our results suggest a general pattern of climate–plant dynamics through geological time, in which land plant diversity is ultimately controlled by global climate state. Plant microfossil compilations show strong climatic control of land plant diversity. Extinctions and emergence of lineages of flowering plants, gymnosperms and ferns were concentrated within the two warmest intervals of the past 130 million years.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"1930-1944"},"PeriodicalIF":15.0,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149182938","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}

Most current strategies modify a single genetic axis, limiting their effectiveness and stability. Here we developed a dual-layer allele engineering framework integrating structure-guided protein design with precise cis-regulatory tuning to overcome such constraints. Using rice 4-hydroxyphenylpyruvate dioxygenase (OsHPPD) as a model, structural analysis enabled the rational design of coding variants that retain enzymatic activity while conferring herbicide resistance. To further enhance resistance, we introduced a highly efficient 22-bp expression-modulating element into the engineered alleles, generating combinatorial coding and regulatory variants with significantly improved resistance, up to four times the recommended field application rate. Importantly, the dual-layer strategy was successfully applied in polyploid wheat, demonstrating its robustness and cross-species applicability. Our work establishes a versatile framework for functional allele engineering, offering a precise and broadly applicable route for crop improvement. While editing the HPPD protein or its expression alone falls short, doing both at once gives strong herbicide tolerance in rice and wheat, pointing to a general way to engineer dosage-sensitive crop traits.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"1995-2009"},"PeriodicalIF":15.0,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149170265","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}
