Original sequence data of ammonia-oxidizing bacteria (AOB) (PRJCA048298)
Soil was collected from layer of a grassland in Dafang County, Guizhou Province, China, where limestone-derived soils are typical of karst landscapes. According to FAO-UNESCO classification, the soils are Calcic Cambisols. After air-drying and sieving, soil was placed into plastic pots. White clover and perennial ryegrass were co-planted, and different forms of nitrogen were added. After four months, soils from each pot were homogenized and stored for molecular analyses. Bacteria-amoA genes were sequenced on the Illumina MiSeq platform.
