Genetic mechanisms underlying variation in seasonal reproduction among stickleback ecotypes
For any organism to have offspring, it is critical for it to consider “when to propagate.” This is particularly true for organisms living in regions with seasons such as temperate and frigid zones, where they have achieved a diverse evolution of the reproductive period that suits their habitats. Yet, little was known about what changes in genes and the genome triggered such an evolution of the reproductive period that is adapted to seasonal climate conditions.
Our research team has recently discovered that the same gene repeatedly triggers this evolution of the reproductive period in sticklebacks, a model species of evolutionary biology. This proposed research is intended to elucidate the nature of the genes that were altered and how this mutation came about, in order to understand their importance in the evolution of the reproductive period of organisms. This will be achieved by investigating the function of the aforementioned genes and the mutation that caused the reproductive evolution in question.

Message from recipient

I feel honored to have received Inamori Research Grants, which have supported a number of significant research projects. I have renewed my determination to reveal aspects of the evolution of organisms that can be found in our backyard, and to share with everyone how biodiversity has come about, the mechanism of maintaining it, and its appeal.
