Outline of Final Research Achievements |
Here we identified a master transcription factor MpBONOBO (MpBNB) that controls sexual organ development in the liverwort Marchantia polymorpha. MpBNB is expressed in the initial cells that are destined to develop into archegonia and antheridia, suggesting its major role in archegonial/antheridial development. Phylogenetic analysis suggested that MpBNB is a member of an evolutionarily conserved transcription factor family. Arabidopsis BNB1 and BNB2 are redundantly required for specification of generative cell in developing pollen, and are functionally replaceable with MpBNB. These findings suggest evolutionarily conserved role of BNB family proteins in the regulation of germ cell differentiation from gametophytes in land plants.
