Amplicon sequencing of amoA gene: oat rhizosphere
Gene libraries were prepared with primers amoA1F/amoA2R (AOB) and CrenamoA23f/CrenamoA616r (AOA) using Fluidigm two-step access array amplification protocol at the DNA Service Laboratory, Roy J. Carver Biotechnology Center  at University of Illinois (Urbana-Champaign, USA)
