Functional metabolic annotations in the soil virosphere are rare but enriched for carbohydrate-active enzymes (CAZymes) and chitin decomposition functions
An analysis of the Global Soil Virus Atlas reveals that while virus-encoded metabolic genes are globally rare in soils, they are non-randomly enriched for carbohydrate-active enzymes, particularly chitinases, suggesting that ignoring viral contributions may lead to underestimating the functional potential for specific carbon degradation traits in soil metagenomic studies.
