Two GM lines and their parental cultivar, as well as four other potato cultivars, were grown in randomized field plots at two sites and in different years. Rhizosphere samples were taken at three developmental stages during plant growth and analyzed using denaturing gradient gel electrophoresis (DGGE) fingerprints of\n            <jats:italic>Bacteria<\/jats:italic>\n            ,\n            <jats:italic>Actinobacteria<\/jats:italic>\n            ,\n            <jats:italic>Alpha<\/jats:italic>\n            - and\n            <jats:italic>Betaproteobacteria<\/jats:italic>\n            ,\n            <jats:italic>Bacillus<\/jats:italic>\n            ,\n            <jats:italic>Streptomycetaceae<\/jats:italic>\n            ,\n            <jats:italic>Pseudomonas<\/jats:italic>\n            ,\n            <jats:italic>gacA<\/jats:italic>\n            ,\n            <jats:italic>Fungi<\/jats:italic>\n            , and\n            <jats:italic>Ascomycetes<\/jats:italic>\n            . In the bacterial DGGE gels analyzed, significant differences between the parental cultivar and the two GM lines were detected mainly for\n            <jats:italic>Actinobacteria<\/jats:italic>\n            but also for\n            <jats:italic>Betaproteobacteria<\/jats:italic>\n            and\n            <jats:italic>Streptomycetaceae<\/jats:italic>\n            , yet these differences occurred only at one site and in one year. Significant differences occurred more frequently for\n            <jats:italic>Fungi<\/jats:italic>\n            , especially\n            <jats:italic>Ascomycetes<\/jats:italic>\n            , than for bacteria. When all seven plant genotypes were compared, DGGE analysis revealed that different cultivars had a greater effect on both bacterial and fungal communities than genetic modification. The effects of genetic modification were detected mostly at the senescence developmental stage of the plants. The site was the overriding factor affecting microbial community structure compared to the plant genotype. In general, the fingerprints of the two GM lines were more similar to that of the parental cultivar, and the differences observed did not exceed natural cultivar-dependent variability.\n          <\/jats:p>","DOI":"10.1128\/aem.00414-09","type":"journal-article","created":{"date-parts":[[2009,4,18]],"date-time":"2009-04-18T01:10:17Z","timestamp":1240017017000},"page":"3859-3865","update-policy":"http:\/\/dx.doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":113,"title":["Rhizosphere Communities of Genetically Modified Zeaxanthin-Accumulating Potato Plants and Their Parent Cultivar Differ Less than Those of Different Potato Cultivars"],"prefix":"10.1128","volume":"75","author":[{"given":"Nicole","family":"Weinert","sequence":"first","affiliation":[{"name":"Julius Ku\u0308hn-Institut\u2014Federal Research Centre for Cultivated Plants (JKI), Institute for Epidemiology and Pathogen Diagnostics, Messeweg 11-12, 38104 Braunschweig, Germany"}]},{"given":"Remo","family":"Meincke","sequence":"additional","affiliation":[{"name":"Graz University of Technology, Environmental Biotechnology, Petersgasse 12, A-8010 Graz, Austria"}]},{"given":"Christine","family":"Gottwald","sequence":"additional","affiliation":[{"name":"Julius Ku\u0308hn-Institut\u2014Federal Research Centre for Cultivated Plants (JKI), Institute for Epidemiology and Pathogen Diagnostics, Messeweg 11-12, 38104 Braunschweig, Germany"}]},{"given":"Holger","family":"Heuer","sequence":"additional","affiliation":[{"name":"Julius Ku\u0308hn-Institut\u2014Federal Research Centre for Cultivated Plants (JKI), Institute for Epidemiology and Pathogen Diagnostics, Messeweg 11-12, 38104 Braunschweig, Germany"}]},{"given":"Newton C.
