metaTraits is a unified and accessible microbial trait resource that integrates culture-derived trait information from BacDive, BV-BRC, JGI IMG, and GOLD, with genome-based predictions for medium- and high-quality isolate and metagenome-assembled genomes (MAGs) from proGenomes and SPIRE.
metaTraits covers over 2.2 million genomes and more than 140 harmonized traits mapped to standardized ontologies, spanning cell morphology (e.g., shape, size, Gram staining), physiology (e.g., motility, sporulation), metabolic and enzymatic activities, environmental preferences (e.g., temperature, salinity, oxygen tolerance), and lifestyle categories. All records are linked to their original evidence and cross-referenced to both NCBI and GTDB taxonomies.
