Abstract

The phylogenetic composition of bacterial communities in the rhizosphere of three potato cultivars grown at two distant field sites was analysed. Ribosomal gene fragments amplified from total community DNA were hybridized to PhyloChips. A total of 2432 operational taxonomic units (OTUs) were detected by the PhyloChips, of which 65% were found in the rhizosphere of all cultivars at both field sites. From all detected OTUs, 9% revealed a cultivar-dependent abundance at the one or the other field site and 4% at both sites. Differential abundance on the three cultivars was mainly observed for OTUs belonging to the Pseudomonadales, Actinomycetales and Enterobacteriales. More than 40% of OTUs belonging to Bradyrhizobiales, Sphingomonadales, Burkholderiales, Rhodocyclales, Xanthomonadales and Actinomycetales differed significantly in their abundance between the sites. A sequence analysis of six …
