In turn, molecular genetic studies of cichlids have focused primarily on more recently diverged groups. Here, we present an evolutionary hypothesis of the major lineages of cichlid fishes based on DNA sequence data from two nuclear loci. One marker, Tmo-4C4, is a single-copy locus containing a region of amino acid similarity to the muscle protein TITIN. Flanking sequence from a second, microsatellite, locus, Tmo M27, shows similarity to mammalian RAS guanine nucleotide-releasing factor. We compare and combine data from these loci to evaluate phylogenetic performance. In separate and combined analyses, the sequence data support and clarify previous morphological hypotheses of cichlid major-group relationships. Indian and Malagasy cichlids form a basal, paraphyletic group. Neotropical cichlids are the sister clade to an African assemblage composed of the paraphyletic west and Pan-African lineages and a group of east African rift lake taxa. We use a consensus phylogeny of the Cichlidae to trace evolutionary changes in the microsatellite repeat motif at Tmo-M27. Analysis reveals that the repeat region was nearly lost in the ancestor to cichlids and then amplified extensively in African taxa. Results demonstrate that these two new DNA markers could be widely applied in perciform systematics. Furthermore, the comparative approach can unveil mutational dynamics of simple-sequence repeat loci over long periods of fish evolution. Simple-sequence repeat regions are increasingly being found in introns of important regulatory genes. We address issues involving their function and suggest caution in making assumptions of strict neutrality.</dcterms:abstract> <dc:language>eng</dc:language> <dcterms:issued>1998</dcterms:issued> <dc:creator>Zardoya, Rafael</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:33:53Z</dc:date> <dcterms:title>Multilocus phylogeny of cichlid fishes (pisces perciformes) evolutionary comparison of microsatellite and single-copy nuclear loci</dcterms:title> <dc:creator>Meyer, Axel</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/7369"/> <dc:creator>Karl, Stephen A.</dc:creator> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:rights>deposit-license</dc:rights> <dc:contributor>Karl, Stephen A.</dc:contributor> <dc:creator>Streelman, Jeffrey Todd</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:33:53Z</dcterms:available> <dc:contributor>Streelman, Jeffrey Todd</dc:contributor> </rdf:Description> </rdf:RDF>
