| Outline of Final Research Achievements |
Organisms are remarkably adapted to diverse environments, but molecular mechanism underlying environmental adaptation still remains elusive. To address this issue, we utilize a unique Drosophila line, "Dark-fly", which has been maintained for 62 years in a constant dark condition.
We determined whole genome sequence of Dark-fly using next-generation sequencer and identified approximately 220,000 single nucleotide polymorphisms (SNPs) in the Dark-fly genome. To identify SNPs associated with dark-adaptation, we reared mixed populations of Dark-fly and the wild type fly in light and dark conditions. Our analyses of population genome detected environment-dependent selections of the Dark-fly genome. We consequently listed 84 candidate genes potentially involved in the adaptation of Dark-fly. We currently aim to clarify the roles of Dark-fly's SNPs in environmental adaptation using genome editing technology.
