Principal coordinates analyses of the 16S rRNA gene sequences in clone libraries for onion- and sugar beet-associated bacteria. The ordinations were constructed for onion- and sugar beet libraries (A and B, respectively) using UniFrac distances weighted by the relative abundances. OA, OB, SA, and SB denote the experimental field sites. C and UF indicate conventional and UF fertilization, respectively.
