Apart from an Aphanomyces sp. and a Phytophthora sp., baiting from reed rhizosphere samples from flooded, as well as drier, littoral sites revealed only Pythium spp. A total of 67 oomycete isolates was classified according to PCR-RFLP banding patterns and ITS sequencing, and 18 different sequence types could be separated. The majority of these seemed previously unknown species, as indicated by the degree of similarity to those deposited in nucleotide databases. Species communities in both flooded and drier habitats or both reed and oak baits clearly differed from one another, and only few species occurred in both dry and flooded sites, or in both oak and reed baits. A frequently occurring group of related Pythium species appeared to be specifically associated with reed, and these were the only species that proved pathogenic towards this host in vitro. Our study proved that unexplored natural ecosystems harbour diverse communities of oomycete species with specific habitat and host preferences within close-by, but ecologically contrasting, sites. Among the species isolated, those associated with the predominating plant might accumulate and thus may be reed pathogens of considerable importance.</dcterms:abstract> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dc:creator>Mendgen, Kurt</dc:creator> <dc:creator>Wielgoss, Anna Marina</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/8428"/> <dc:contributor>Wielgoss, Anna Marina</dc:contributor> <dcterms:issued>2008</dcterms:issued> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:contributor>Mendgen, Kurt</dc:contributor> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/8428/1/Diversity_host_and_habitat_specificity_of_oomycete_communities_in_declining_redd_stands_Phragmites_australis_of_a_large_freshwater_lake.pdf"/> <dc:rights>deposit-license</dc:rights> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:43:31Z</dc:date> <dc:creator>Nechwatal, Jan</dc:creator> <dcterms:bibliographicCitation>First publ. in: Mycological Research 112 (2008), pp. 689-696</dcterms:bibliographicCitation> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/8428/1/Diversity_host_and_habitat_specificity_of_oomycete_communities_in_declining_redd_stands_Phragmites_australis_of_a_large_freshwater_lake.pdf"/> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
