It is unclear to what extent cultivar type and/or growth stage affect this process.<h4>Methodology/principal findings</h4>DNA-based pyrosequencing was used to characterize the structure of bacterial communities in a field cropped with potato. The rhizospheres of six cultivars denoted Aveka, Aventra, Karnico, Modena, Premiere and Desiree, at three growth stages (young, flowering and senescence) were examined, in addition to corresponding bulk soils. Around 350,000 sequences were obtained (5,700 to 38,000 per sample). Across all samples, rank abundance distributions best fitted the power law model, which indicates a community composed of a few highly dominant specPloS onee23321https://www.ebi.ac.uk/biostudies/studies/S-EPMC3158761biostudies-literatureComparative analysis of bacterial communities in a potato field as determined by pyrosequencing.PMC3158761Salles JFSemenov AVvan Elsas JDAl-Soud WAInceoglu OfalseComparative analysis of bacterial communities in a potato field as determined by pyrosequencing.<h4>Background</h4>Plants selectively attract particular soil microorganisms, in particular consumers of root-excreted compounds.
