Here we present a chromosome-scale genome assembly of Hordeum brevisubulatum (II, 2n = 2x =14) and genome resequencing of 38 diploid germplasms spanning 7 I-genome species. We reveal that the adaptive evolution of the H. brevisubulatum genome is shaped by structural variations, some of which may contribute to its adaptation to high alkali and salt environments. Evolutionary duplication of the stress sensor-responder module CaBP-NRT2 and the horizontally transferred fungal gene Fhb7 were identified as novel alkaline–saline tolerance mechanisms. We also demonstrate the potential of the Hordeum I genome in crop breeding through the newly synthesized hexaploid Tritordeum (AABBII) with enhanced alkaline–saline tolerance. Our study fills critical gaps in Hordeum genomics and CWR research, advancing introgression of CWR resources into current crops for sustainable agriculture. The authors present a reference genome for Hordeum I-genome species.

Although recent studies have shown m6A effects on determining the fate of mRNA through modulating various aspects of plant mRNA metabolism, whether and how m6A affects gene transcription in plants remains elusive. Here we show that NEEDED FOR RDR2-INDEPENDENT DNA METHYLATION (NERD), a plant-specific protein, is an essential component of the m6A methyltransferase complex required for regulating the transcription of a central floral repressor FLOWERING LOCUS C (FLC) in Arabidopsis. NERD interacts with and stabilizes the two core methyltransferases, mRNA adenosine methylases A and B, to promote m6A modification of nascent RNA, conferring an overall negative effect on gene transcription. At the FLC locus, NERD-mediated m6A modification on the nascent transcript negatively affects H3K36me3 deposition and FLC transcription through NERD interaction with the H3K36me3 methyltransferase SET DOMAIN GROUP 8. Collectively, our findings reveal that NERD mediates the crosstalk between epitranscriptomic and epigenetic regulation of FLC to modulate flowering in Arabidopsis. This study reveals NERD, a zinc finger protein, as an essential component of the plant m6A methyltransferase complex that mediates epitranscriptomic and epigenetic regulation of the floral repressor gene FLC to modulate flowering in Arabidopsis.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"468-482"},"PeriodicalIF":15.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618714","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}

In line with the fungus’s apoplastic lifestyle, STB resistance genes isolated to date encode receptor-like kinases (RLKs) including a wall-associated kinase (Stb6) and a cysteine-rich kinase (Stb16q)3,4. Here we used genome-wide association studies on a diverse panel of 300 whole-genome shotgun-sequenced wheat landraces (WatSeq consortium5) to identify a 99-kb region containing six candidates for the Stb15 resistance gene. Mutagenesis and transgenesis confirmed a gene encoding an intronless G-type lectin RLK as Stb15. The characterization of Stb15 exemplifies the unexpected diversity of RLKs conferring Z. tritici resistance in wheat. Stb15 provides resistance to Septoria tritici blotch in wheat and encodes a G-type lectin receptor-like kinase. The three cloned Stb genes, which are effective against different pathogen isolates, encode diverse receptor-like kinases with extracellular domains potentially involved in sugar binding.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"410-420"},"PeriodicalIF":15.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41477-025-01920-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618503","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}

In mosses, which retain features of ancestral land plants, the gametophyte is dominant and has an independent existence. However, in flowering plants the gametophyte has undergone evolutionary reduction to just a few cells enclosed within the sporophyte. The gametophyte is thought to retain genetic control of its development even after reduction2. Here we show that male gametophyte development in Arabidopsis, long considered to be autonomous, is also under genetic control of the sporophyte via a repressive mechanism that includes large-scale regulation of protein turnover. We identify an Arabidopsis gene SHUKR as an inhibitor of male gametic gene expression. SHUKR is unrelated to proteins of known function and acts sporophytically in meiosis to control gametophyte development by negatively regulating expression of a large set of genes specific to postmeiotic gametogenesis. This control emerged late in evolution as SHUKR homologues are found only in eudicots. We show that SHUKR is rapidly evolving under positive selection, suggesting that variation in control of protein turnover during male gametogenesis has played an important role in evolution within eudicots. Ancestral land plants had a free-living gametophyte, but in flowering plants the gametophyte develops within the sporophyte. This study shows that male gametophyte development in Arabidopsis is directed by the sporophyte through repression of gametogenesis genes.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"398-409"},"PeriodicalIF":15.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618504","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}

In the case of dual-floret spikelets, the upper fertile floret develops normally to form a single grain, while the lower sterile floret undergoes abortion. Here we elucidate the role of Double-Grain 1 (DG1), a gene encoding a homeobox-domain-containing protein, in regulating the lower floret meristem activity and double-grain spikelet trait in sorghum. A 35.7-kb paracentric inversion in the DG1 promoter region leads to increased DG1 expression, probably by reducing repressive histone modifications. This increase in DG1 expression transforms the degenerated lower floret into a fertile one. The use of the superior DG1 allele results in an increase of approximately 40.7% to 46.1% in grain number per panicle and a 10.1% to 14.3% increase in overall grain yield. Our findings shed light on the sorghum double-grain spikelet characteristic, offering valuable insights for high-yield breeding designs in cereals. A 35.7-kb inversion in the DG1 promoter increased DG1 expression in sorghum, inducing double-grain spikelets by restoring fertility to the lower floret.
