Outline of Final Research Achievements

In order to investigate the origin and evolution of the multicellular body plan in land plants and charophycean algae, in this study, we compared their multicellular gametophyte and sporophyte generations based on their genes and genomes. We identified shared genes among land plants and charophycean algae, as well as homologues of the important developmental genes, which have been identified in model species of land plants, from charophycean algae. Moreover, we explored the expression/function of these developmental genes in charalean algae and discussed the origin and evolution of the multicellular body plan in land plants and charophycean algae.
