We aim to study the basis of animal behavior on the level of molecular, cell and individual.
Our research
This laboratory is devoted to the study of molecular and cellular bases of innate behavior, with special reference to the genetic mechanism whereby the behavior has diversified in evolution. Our favorite organism is the fruit fly Drosophila, which is highly amenable to genetic analysis. We succeeded in isolating a mutant strain, satori, the males of which engage in homosexual courtship. satori mutants harbor a mutation in the gene fruitless (fru), which encodes a set of transcription factors Fru proteins that are translated only in the male but not female neurons. We discovered that the presence or absence of Fru determine the sex difference in the structure and survival of expressing neurons. A specific set of male-specific neurons thus produced respond to the key stimuli and initiate male courtship. We are in the process to unveil the entire circuitry for courtship.
