Skeleton phylogeny reconstructed with transcriptomes for the tribe Drosophilini
Drosophila FallÃ©n, 1832 is the most speciose genus occupying approximately 28% (1,263 spp.) of all known species (4,465 spp.) in the family Drosophilidae. Flies of this genus are distributed all over the world and show very high diversity in various ecological, ethological, physiological, and morphological traits. This genus is thus one of the most important model systems in evolutionary biology. Additionally, research using these Drosophila model organisms has greatly contributed to development of important concepts and theories in modern genetics and revealed molecular and physiological mechanisms of various traits. However, due to the less sufficient taxon sampling from minor lineages and non-Drosophila genera, the evolutionary history of the tribe Drosophilini remains an unsolved problem. Therefore, to elucidate the molecular phylogenetic relationships in the tribe Drosophilini, we carried out phylogenetic analysis using a large number of transcriptome-based gene sets, focusing on the largest, core tribe Drosophilini in the Drosophilidae.
