<strong>Soil microbial gene abundance determines soil multifunctionality in Tibetan alpine grasslands</strong>

Soil microbes play a vital role in maintaining soil multifunctionality (SMF) that relates to carbon (C), nitrogen (N), and phosphorus (P) cycles and is severely threatened by climate change. However, how different microbial attributes such as microbial gene abundance, diversity, and network complexity affect soil multifunctionality is poorly understood. In this manuscript, we stressed the effects of diverse bacterial and fungal properties on soil multifunctionality including C sequestration and decomposition, nutrient mineralization and cycling, and microbial acquisition of C, N, and P resources along a natural precipitation gradient in Tibetan alpine grasslands. Our work is pivotal for understanding the roles of soil microbial communities in modulating soil multifunctionality under precipitation changes.
