  "abstract": "The discovery of RNA viruses from metatranscriptomic data remains challenging due to extreme sequence divergence and length heterogeneity, ranging from massive polyproteins to short assembly artifacts. We present Rider, a two-stage framework that synergizes deep representation learning with scalable domain-specific structural validation. In the first stage, Rider leverages a compact pretrained protein language model to broadly detect highly divergent viral signals. To overcome the inherent input length limitations of language models and accurately capture catalytic core domains, the second stage employs an overlapping sliding-window structure prediction strategy. These structures are then aligned against our curated database of non-redundant RdRp (RNA-dependent RNA polymerase) domains. This domain-centric design detects RdRp domains embedded within long polyproteins and truncated fragments. Across >10,000 metatranscriptomes spanning diverse ecosystems, Rider achieves sensitivity comparable to LucaProt, recalling >99% of previously cataloged RNA viruses. Rider identifies thousands of deeply divergent sequences and clades that elude existing methods. In a human inflammatory bowel disease (IBD) cohort, Rider agrees with other methods in detecting RNA viruses while extending detection to divergent lineages, providing a scalable pipeline for global RNA virome exploration.",
