Precipitation increase promotes soil organic carbon formation and stability via the mycorrhizal fungal pathway

Proceedings of the National Academy of Sciences, Volume 122, Issue 48, December 2025. <br/>SignificanceChanges in soil organic carbon (SOC) critically influence the future climate. Arbuscular mycorrhizal fungi (AMF) are critical regulators of SOC dynamics, yet the impacts of climate-induced changes, such as precipitation increase (Pi), on AMF- …
