| Outline of Final Research Achievements |
We studied the logics of plant development from a point of evolutionary view using the liverwort, Marchantia polymorpha, a member of basal land plant lineages as a model. We developed the genome database, genome editing vectors, and other molecular tools for experimental biology of M. polymorpha. By the comparative and reverse genetic studies of fundamental factors known to regulate angiosperm development, we showed that the common ancestor of land plants had acquired the basic system of plant development including auxin-dependent three-dimensional growth, light signaling pathways, cell division regulation, and environmental induction of sexual reproduction. Starting with the mutant analysis and its causal gene identification in M. polymorpha, we identified the master regulator, BONOBO, which determines the germline cell lineage in land plants. We concluded the evolutionary strategies to plant developmental biology are highly effective and informative.
