Fig. 6From: pH rather than nitrification and urease inhibitors determines the community of ammonia oxidizers in a vegetable soilNeighbor-joining phylogenetic tree of AOA amoA gene sequences retrieved from the vegetable soil. Sequences from this study are shown in bold and are described as clone name (accession number) T-RF size. Bootstrap values (>50%) are indicated at branch points. Reference sequences are described as clone name (environment, accession number). The number in bracket means clones. The scale bar represents 0.5% estimated sequence divergenceBack to article page
