Our unifying goal is to understand the diversity and evolution of higher plants. Toward this end, we are investigating particular plants found in Japan and adjacent areas from various aspects. We are also involved in the management of Makino Herbarium (MAK).

Taxonomy and Phylogeny of Higher Plants
Image
Phylogenetic relationship of Asarum cordifolium and its related species
To understand the diversity and evolutionary history as well as the evolutionary process of higher plants, we are investigating several plant groups such as Aristolochiaceae, Rutaceae, Scrophulariaceae, etc.
Phytogeography

Chloroplast DNA phylogeny and phytogeography of Pedicularis chamissonis var. japonica
Each plant usually has a distinct area of distribution with varying geographical distribution. To infer the evolutionary history or past migration of plants we are investigating the geographical genetic variations of chloroplast or nuclear DNA on some alpine or temperate plants.
Floral and Reproductive Biology in Flowering Plants

Heterostyly found in Psychotria homalosperma
To understand the evolution of flowering plants it is important to know not only how plants vary in floral structure but also how their reproductive systems serve to maintain their natures. We are investigating insect-pollinated plants with peculiar floral structures, and plants with sexual polymorphism or heterostylous nature in flowers.
