Abstract |
The species flocks of cichlid fishes in the East African Great Lakes are a prime model system in evolutionary biology. Lakes Tanganyika, Malawi, and Victoria are each teeming with a unique set of hundreds of endemic cichlid species that have evolved in a few millions to several thousands of years only. The factors underlying explosive speciation in cichlids remain unclear, however. Recently, cichlids have been established as a model system in evolutionary genetics and genomics and five cichlid species are currently being sequenced at Broad Institute of MIT and Harvard. This provides entirely new possibility to study the genetic and genomic basis of the evolutionary success of cichlid fishes. In this project, we plan to make use of these new possibilities, by making use of the forthcoming cichlid genomes and applying next generation sequencing technology to obtain twelve new transcriptomes of cichlid fishes. We intend to search for special genomic features in cichlids and to test for the significance of gene duplication and copy number variation in cichlid evolution. With the evolutionary and comparative genomic analysis of new genome and transcriptome data we expect exciting new insights into the genetic and genomic basis of organismal diversification in general and of cichlid evolution in particular. |
