Generality and diversity of development in land plants.

Comparisons of development in several model animals showed that basal developmental gene regulatory networks were established at their common ancestor and subsequent modification caused present developmental diversity. In contrast to animals, comparisons of development in land plants were not possible because of the lack of feasible models with genome information and developmental studies in non-flowering plants. However, in the last ten years, draft sequences of the lycopod Selaginella moellendorffii and the moss Physcomitrella patens genomes were published by the international consortia and substantial amounts of developmental studies were accumulated in P. patens, in which gene targeting is feasible. In this talk, I will summarize the studies and discuss on the common mechanisms of development in land plants. As well as the common features, many specific developmental mechanisms evolved in specific lineages are also still unrevealed because of the difficulty in obtaining genome information and gene manipulation techniques. Technical advancement in genome sequencing and gene manipulation techniques makes possible to analyze non-model plants including carnivorous plants, Mimosa pudica, and Houttuynia cordata in my laboratory. I will introduce our recent progress on the evolution of pitcher leaves and digestive enzymes in carnivorous plants.
