| Research Abstract |
In order to study the evolution of mycophagy in Drosophilidae, I reconstructed the phylogenetic tree for several mycophagous and non-mycophagous species of Drosophilidae. In the phylogenetic tree, mycophagous species did not regarded as a monophyletic group. This result suggests that the mycophagous character occurred several times independently. Next, in order to identify the genetic basis of mycophagy, I compared the nucleotide sequences of some candidate genes between the mycophagous and non-mycophagous species in Drosophilidae. However, I fail to detect any variant specific to mycophagy. Therefore, more analyses will be required to solve this problem.
