Surprisingly, fungal cell-wall chitin elicits robust immune responses without causing growth inhibition, yet constitutive intracellular chitin signalling severely impairs growth. How plants resolve this paradox remains unclear. Here we identify two chitin-inducible, paralogous apoplastic chitinases in Arabidopsis thaliana, MIC1 and MIC2, both possessing direct antifungal activity through chitin hydrolysis. MIC2 generates immunogenic chitin oligomers that activate chitin-triggered immunity, whereas MIC1 ultimately degrades chitin into non-immunogenic dimers and monomers, thereby dampening growth-inhibitory signalling. This functional divergence is dictated by Asn137 glycosylation in MIC1. Removing this N-glycan converts MIC1 into a MIC2-like enzyme. MIC1-like chitinases are widespread in plants, and Oryza sativa Osmic1 mutants exhibit enhanced fungal resistance without growth defects. Our work defines an N-glycosylation code that governs the functional specialization of paralogous chitinases and provides a conserved molecular target for breeding crops with improved fungal resistance and uncompromised growth. This work reveals an N-glycosylation code that distinguishes two Arabidopsis chitinase paralogues, directing them to produce or degrade immunogenic chitin oligomers. This enables plants to gain chitin-triggered fungal resistance without a growth penalty.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"2073-2088"},"PeriodicalIF":15.0,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087599","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 maternal epigenetic mechanisms that regulate offspring development remain unclear. Here we profiled the H3K27me3 landscape in maternal integuments and demonstrated that epigenetic changes in maternal tissues shape embryonic patterning. Dynamic changes in H3K27me3 in the integuments are crucial for the activation of the auxin-transport genes AUX1 and LAX1, which allow auxin to accumulate in the micropylar integuments to which the embryo attaches. Deficiencies in H3K27me3 demethylase activity or AUX1/LAX1 expression reduce auxin levels in the micropylar integuments. This disrupts maternal-to-embryo auxin transport, leading to reduced auxin levels in the embryo and thus perturbing embryonic patterning. Our findings reveal a previously unrecognized mechanism of maternal epigenetic regulation that governs embryonic patterning. Post-fertilization remodelling of H3K27me3 in integuments regulates the timely activation of auxin transport genes, thereby facilitating maternal-to-embryo auxin transport and shaping embryonic patterning.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"2042-2054"},"PeriodicalIF":15.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087600","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, using interval assays, genome-wide crossover maps, genetic mapping of recombination modifiers and targeted genetics, we show that cold shifts crossovers towards subtelomeric regions and increases class II pathway output. Genetic mapping identified a major temperature-responsive locus on chromosome 4, resolved to a 15.6-kb interval containing SNI1, the Arabidopsis NSE5 orthologue and a component of the SMC5/6 complex. Reduced SNI1 function alters the temperature response of meiotic recombination, promoting a subtelomere-biased crossover landscape. Cytology in zip4 mutants shows that SNI1 limits class II crossover formation at 21 °C and that cold weakens this constraint. SNI1 also promotes longer synaptonemal complexes at 21 °C, although total SC length does not by itself predict crossover output. Our data identify SNI1/NSE5 as a temperature-sensitive brake on class II crossovers. Cold temperature alters meiotic recombination in Arabidopsis by weakening SNI1/NSE5, a chromosome architecture factor that normally limits class II crossovers and shapes where genetic exchange occurs.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"2026-2041"},"PeriodicalIF":15.0,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41477-026-02400-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021253","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}

Eddy-covariance and tree-ring analyses have suggested a decoupling between photosynthetic carbon assimilation and growth on interannual timescales4,5, often interpreted as evidence for widespread sink limitation5. Using long-term observations at flux towers and a global vegetation model ensemble, we show that such annual, or short-term, decoupling neither implies sink limitation nor constrains long-term growth. Across observations and more than half of the ensemble models, short-term correlations between photosynthesis and woody carbon biomass increment (rΔcWood,GPP) are weak, confirming previously reported decoupling. Despite the weak correlations, however, woody carbon biomass increased in proportion to photosynthesis between 1951 and 2020. Notably, there is no relationship between rΔcWood,GPP and the long-term sensitivity of biomass to photosynthesis across models. These results caution against inferring source–sink control from observational records and suggest that sink limitation is probably less prevalent than previously reported. Using long-term observations and global vegetation models, Nguyen et al. show that the decoupling between photosynthesis and plant wood growth reported in recent studies neither implies sink limitation nor constrains long-term biomass growth.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 10","pages":"1923-1929"},"PeriodicalIF":15.0,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021254","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 present the crystal structure of an Arabidopsis immune complex comprising the CRP SMALL PHYTOCYTOKINES REGULATING DEFENSE AND WATER LOSS (SCREW), the receptor PLANT SCREW UNRESPONSIVE RECEPTOR (NUT) and the coreceptor BRASSINOSTEROID INSENSITIVE 1-ASSOCIATED RECEPTOR KINASE 1 (BAK1). Unlike typical multi-disulfide CRPs with compact folds, SCREW maintains a flexible loop constrained into a neck-ring-like conformation through stabilization by a single disulfide bond and a critical proline residue. In the complex, SCREW’s carboxy-terminal cyclic region inserts between NUT and BAK1, burying a large surface area on BAK1. Disrupting this neck-ring-like conformation or its key interfaces abolishes complex assembly and downstream signalling. This assembly mechanism is conserved in rapeseed and probably among other dicots. Our work reveals a distinct disulfide-dependent conformation, critical for receptor activation and potentially common among two-cysteine CRPs. SCREW peptides adopt a disulfide-dependent neck-ring-like conformation to induce the activation of the NUT–BAK1 immune receptor complex, which may represent a common mechanism among secreted cysteine-rich peptides with only two cysteines.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"12 9","pages":"1756-1768"},"PeriodicalIF":15.0,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981593","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}
