In this study, fifteen soilswith an AP gradient from 5.03 mg kg-1 to 391.45 mg kg-1 were collected from the topsoil layer (0-20 cm) from different fields in the suburbs surrounding Beijing, north China.. The effect of available phosphorus on soil fungal community

The role of soil microorganisms in soil nutrient cycling is important and has been widely investigated. Although the influence of phosphorus (P) on soil microbial communities has been determined using low levels of available P (AP), the composition of soil fungal communities and their relationship with soil properties with significant variations in AP concentration levels are still poorly understood. In this study, fifteen soilswith an AP gradient from 5.03 mg kg-1 to 391.45 mg kg-1 were collected from the topsoil layer (0-20 cm) from different fields in the suburbs surrounding Beijing, north China. High throughput sequencing was used to analyze the fungal communities using the Illumina Miseq platform based on the ITS gene. Our results showed that Ascomycota, Basidiomycota, Ciliophora and Zygomycota were the dominant phyla in all soils. Results from our study showed that fungal α-diversity was significantly decreased in soils with a high AP concentration (> 120 mg kg-1) compared with soils with an AP < 50 mg kg-1; β-diversity was not affected by AP concentration. In the genus level, it found that 10 genera were changed with the increasing AP concentration. In a word, AP could impact the soil fungal community in our study.
