Outline of Final Research Achievements

Using the liverwort Marchantia polymorpha, we identified BONOBO, a master regulator of sexual reproduction induction in the plant gametophytic generation, and elucidated the molecular mechanisms of spatiotemporal and environment-dependent regulation of sexual reproduction induction. We also found that female differentiation occurs when the feminization factor FEMALE GAMETOPHYTE MYB (FGMYB) is expressed, and male differentiation occurs when SUPPRESSOR OF FEMINIZATION, a long non-coding (lnc) RNA encoded on its complementary strand, is expressed, and that the regulation of lncRNA-mediated transcriptional repression. Furthermore, we identified a sex-determining factor, BPCU, encoded on the sex chromosome in a sexually dimorphic haploid organism for the first time , and showed that this sex-determining factor functions via regulation of FGMYB locus on the autosome.

Academic Significance and Societal Importance of the Research Achievements

配偶体世代の環境依存的な有性生殖誘導、性分化、性決定において、転写制御ネットワークとエピジェネティックな制御により頑健性と可塑性が達成されることが明らかになった。この制御システムを分子系統学的位置付けと合わせて考察することにより、植物生殖の制御機構の理解が大きく進んだ。また、約100年前に植物として初めて性染色体が発見されたコケ植物から性決定因子が同定されたことで長年の謎が解明されたという意義がある。また、性決定因子には性染色体間の相同遺伝子が存在し、有性生殖誘導機能を共有することを明らかにした。これは予想外の発見であり、性染色体進化や多様な性決定に関する新たな知見を加えた。
