Since its inception, RNA sequencing (RNA-seq) technology has revolutionized our ability to analyze gene expression, discover novel transcripts, and identify differential splicing events at the whole-transcriptome level. This review systematically outlines the development of RNA-seq technologies, focusing on comparing the principles, workflows, advantages and disadvantages, and application scenarios of three mainstream technical approaches: short-read cDNA sequencing, long-read cDNA sequencing, and long-read direct RNA sequencing. Short-read sequencing remains the gold standard for quantitative analysis due to its high accuracy and low cost; long-read cDNA sequencing (e.g., PacBio and Nanopore cDNA sequencing) can seamlessly span repetitive regions and homologous genes, enabling precise reconstruction of transcript isoforms; while the emerging long-read direct RNA sequencing (e.g., Nanopore) preserves native RNA modification information, opening new avenues for epitranscriptomics research. The article also reviews the latest applications of RNA-seq in disease research, developmental biology, and single-cell analysis, and discusses future directions, such as multi-omics integration, improvement of long-read quantification accuracy, and development of bioinformatics tools.
