Multicellularity emerged independently in plants and animals. There are crucial differences between the development of land plants and animals, such as, cell movement, germline, rigidity, and plasticity etc… We are interested in the fundamental regulatory mechanism of multicellularity in plants, and how the regulatory system diverged in the evolution of land plants.
Emergence of land plants, approximately 480 million years ago, was one of the major events for the life on planet earth. Liverworts, as extant representatives of the earliest land plants, are a key group to understand the regulatory mechanisms and the evolution of plant development. Marchantia polymorpha is a common, well-propagating, dioecious liverwort species, and the haploid gametophytic generation dominates over the diploid sporophytic generation in its life cycle. We focus on the potential of M. polymorpha as a model plant for molecular genetics, and have been developing crucial experimental procedures and resources, such as efficient genetic transformation, induction of reproductive growth in laboratory condition, genetic map, establishment of standard line, mutagenesis, EST, and genomic sequencing. Our system founded on M. polymorphashould contribute to fundamental understanding of the regulatory mechanisms that mediate plant development and the evolution of the developmental machinery in plants.
