The objective of this study was to explorefunctional groups(alkaline phosphomonoesterase ALP and β-propeller phytaseBPP)of microbes driving soil P turnover.Diversity of ALP-and BPP-encoding genes in the hyphosphereofAllium porrum was studied with the combination of compartmented microcosms and high-throughput sequencing technologies.Leek was grown with or without the AM fungus Funneliformismosseaein root compartment,and the extraradical mycelium of F.mosseae was allowed to grow into a separate hyphal compartmentcontaining no P,KH2PO4or phytin.Illumina MiSeq sequencing revealed community compositions ofALP-and BPP-harboring bacteriausing the specific primer pairs.Different P formssignificantly changedthe bacterial ALP-and BPP-harboring community structures.The more abundant community compositions of ALP-harboring bacteria were Sinorhizobium,Bradyrhizobium,Pseudomonasand Ralstonia,and specifically,organic P treatmentssignificantlyincreased relative abundance of Pseudomonas compared with control and inorganic P treatments.Likewise,the predominant community composition of BPP-harboring bacteria was Pseudomonas,moreover,the highest abundance was presented in organic P treatments.These results show that community composition on bacterial ALP and BPPgenesare meditated by P forms and the dominant bacteria harboring these two genes was Pseudomonas,which might drive the turnover of soil Pin bacterial communitiesand consequently manipulate the biogeochemical cycle of soil P.
