Ecological diversity and co-occurrence patterns of bacterial community through soil profile in response to long-term switchgrass cultivation

Abstract Switchgrass (Panicum virgatum L.) is a cellulosic biofuel feedstock and their effects on bacterial communities in deep soils remain poorly understood. To reveal the responses of bacterial communities to long-term switchgrass cultivation through the soil profile, we examined the shift of soi...
