Yet existing spatial transcriptomics tools are still limited in either transcriptomic coverage or spatial resolution, hindering unbiased, hypothesis-free transcriptomic analyses at high spatial resolution. Here, we develop reverse-padlock amplicon-encoding fluorescence <em>in situ</em> hybridization (RAEFISH), an image-based spatial transcriptomics method with whole-genome coverage and single-molecule resolution in intact tissues. We demonstrate the spatial profiling of transcripts from 23,000 human or 22,000 mouse genes in single cells and tissue sections. Our analyses reveal transcript-specific subcellular localization, cell-type-specific and cell-type-invariant zonation-dependent transcriptomes, and gene programs underlying preferential cell-cell interactions. Finally, we further develop our technology for the direct spatial readout of guide RNAs (gRNAs) in an image-based, high-content CRISPR screen. Overall, these developments offer a broadly applicable technology that enables high-coverage, high-resolution spatial profiling of both long and short, native and engineered RNAs in many biomedical contexts.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"53 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195044","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}

The analyses revealed that black soybeans serve as a critical domestication intermediate, and soybean domestication traits were selected in a stepwise manner. Comparisons across accessions from diverse geographical areas and historical eras identified numerous selected genes that have contributed to trait enhancement and environmental adaptation during the global dissemination and unveiled a temporal shift of breeding priorities in soybean improvement in China. To highlight the allele utilization among soybean varieties, we constructed a variation map and quantitative trait nucleotide (QTN) library.

Across 274 Mtb clinical isolates, we uncovered unexpected diversity in virulence gene expression, which we linked to known and unknown regulators. Surprisingly, we found that many isolates harbor variants associated with decreased expression of EsxA (Esat6) and EsxB (Cfp10), which are virulence effectors, dominant T cell antigens, and immunodiagnostic targets. Across &gt;55,000 isolates, these variants associate with increased transmissibility, especially in drug-resistant Mtb strains.

However, the molecular mechanisms bridging transposon activity and CRISPR immunity remain unclear. We identify TranCs (transposon-CRISPR intermediates) derived from distinct IS605- or IS607-TnpB lineages. TranCs utilize both CRISPR RNAs and reRNAs to direct DNA cleavage. The cryoelectron microscopy (cryo-EM) structure of LaTranC from <em>Lawsonibacter sp.</em> closely resembles that of the ISDra2 TnpB complex; however, unlike a single-molecule reRNA, the LaTranC guide RNA is functionally split into a tracrRNA and crRNA. An engineered RNA split of ISDra2 TnpB enabled activity with a CRISPR array.

We introduce single-cell full-length EU-labeled nascent RNA sequencing (scFLUENT-seq), a single-cell nascent RNA sequencing method using brief 10-min metabolic labeling to capture genome-wide transcription. Surprisingly, individual cells—from splenic lymphocytes to pluripotent stem cells—transcribe only ∼0.02%–3.1% of the genome, versus &gt;80% in bulk, revealing limited genome engagement and profound cell-type and cell-to-cell heterogeneity. Intergenic transcription, especially from heterochromatin, is pervasive and stochastic. Promoter-associated antisense and genic transcription rarely co-occur in the same cell. Proximal intergenic transcription involves both gene readthrough and independent initiation, while distal intergenic transcription is largely independent of neighboring genes and correlates with increased transcriptional diversity, a hallmark of cellular plasticity. Although global RNA synthesis and turnover are coupled in bulk, individual mRNA transcription and decay are poorly coordinated in single cells, suggesting noise-buffering mechanisms. Overall, scFLUENT-seq uncovers complex coding and noncoding transcriptional dynamics that underlie single-cell heterogeneity and state transitions.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"89 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140599","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}

This compels identification of cancer-restricted cell-surface protein antigens, which are rare.
