%X Litter decomposition is one of the most important and dynamic components of nutrient cycling in ecosystems. In addition to the well-known actions of plant roots on litter, roots also constitute an important biotic factor regulating litter decomposition. However, relatively little attention has been given to this. Relative to the upper litter layer, the middle and lower layers are enriched in water and nutrients, which provide favorable conditions for root growth. By proliferating in litter, roots potentially influence litter decomposition through a priming effect, mycorrhizal fungi and N uptake. We give an overview of root foraging in litter, including factors influencing it. We then review its influence and possible mechanisms of root growth on litter decomposition. We also propose a conceptual module that enhances understanding of the relationship between root and litter decomposition.
