Though meta-analysis mitigates these issues, its application in rice research remains limited. Here, we report a large-scale meta-analysis of six independent GWAS experiments in rice to mine genes for key agronomic traits. By integrating a rice pan-genome graph to identify structural variants, we obtained 6,604,898 SNP and 42,879 PAV variants for the six panels (7765 accessions). Meta-analysis significantly improved quantitative trait loci (QTLs) detection and hidden heritability by up to 43 and 37.88%, respectively. Among 156 QTLs identified for six agronomic traits, 116 were exclusively detected through meta-analysis, highlighting its superior resolution. Two novel QTLs governing grain width and length were functionally validated through CRISPR/Cas9, confirming their candidate genes. Our findings underscore the utility and potential advantages of this pan-genome-based meta-GWAS approach, providing a scalable model for efficiently gene mining from diverse rice germplasms.</p>","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"7 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To the best of our knowledge, enantio-, atrop-, and diastereoselective macrocyclizations are yet to be reported. Herein, we describe an N-heterocyclic carbene (NHC) and chiral phosphoric acid (CPA) dual-catalytic process for the desymmetrization of 1,3-diols, to achieve macrocyclization and stereoselective control over two chiral elements. It is deduced that the hydrogen bonding of CPA with the 1,3-diols enhances the diastereoselectivity of the process. As a result, various planar-chiral cyclophanes bearing chiral ansa chains are synthesized. Thermodynamic experiments reveal that the presence of an all-carbon quaternary carbon center on the ansa chain significantly increases the rotational barriers of the cyclophanes. Moreover, density functional theory calculations suggest that the chiral substituent shrinks the ansa chain by compressing the bond angle, thereby rendering the conformational rotation reaction more challenging.</p>","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"1 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
