Recent Activities

Sexual reproduction ensures genetic diversity, and the modes of sex determination and their underlying molecular mechanisms are highly diverse. Bryophytes, which are the sister group to vascular plants, determine sex during the haploid generation. Using the model liverwort Marchantia polymorpha, a dioicous species with sex chromosomes, together with a closely related monoicous species, we have conducted comparative genomic analyses to elucidate how sex chromosomes evolved during the transition from dioicy to monoicy.

Message to Students

With the goal of understanding evolution, we study environmental responses and sexual reproductive systems using bryophytes. We take a broad approach, ranging from genomic analyses to fieldwork. Why not join us in exploring the secrets behind the diversity of life in graduate school?
