Deciphering Transcriptome Complexity via Long-read Sequencing
Long-read sequencing is transforming transcriptomics from gene-level quantification to isoform-resolved interpretation by directly resolving full-length transcript structures, transcription in repetitive regions, and linked molecular features; this review provides an end-to-end roadmap covering sequencing platforms, library preparation strategies, computational workflows, the analysis of transcriptome complexity, and downstream analyses; it further highlights current challenges, and emerging frontiers including single-cell and spatial transcriptomics, direct RNA modification detection, and integrated multi-omics approaches.
- Long-read sequencing enables isoform-resolved characterization of transcriptome complexity by directly resolving full-length transcript structures and linked regulatory features.
- The choice of sequencing platform and library preparation strategies critically influences transcript completeness, accuracy, and biological interpretation.
- Standardized computational workflows are needed for reproducible and scalable long-read transcriptomics studies.
- Single-cell, spatial, direct RNA, and multi-omics approaches expand long-read omics frontiers.
