PomBase in 2026: expanding knowledge, modeling connections.

PomBase is the model organism database dedicated to the fission yeast Schizosaccharomyces pombe. In this update, we outline recent progress in literature curation, the introduction of new tools, and enhancements designed to better support the research community. We highlight our recent effort to curate biological pathways and modules as causal networks using Gene Ontology-Causal Activity Modelling and describe new features that utilize these models to guide and inform hypothesis-driven research.
