The Department of Botany consists of two major courses. In the molecular plant science course, we are studying the perception and transduction of external environmental signal, the diversity of timing systems and their structural bases, the genome-scale gene expression regulation in response to environmental stimuli, and the physiology and molecular biology of chloroplasts and mitochondria. In the evolutionary plant science course, we study plant phylogeny and taxonomy, including plant diversity, plant phylogenetic evolution and mechanisms of plant speciation, by means of fieldwork, morphology, anatomy, cytology, DNA sequencing and genome-wide analysis.

Core Course

Plant Physiology

We are conducting longitudinal research on the signal transduction mechanism of plant light response from molecules to cells, individuals, and ecological levels.


We are conducting research on the formation of dynamical systems for living organisms using plants and microorganisms as materials.

Plant Molecular Physiology

We are conducting research at the gene, protein, and cell levels, making full use of various methods to understand the amazing ability of plants to adapt to their environment.

Plant Molecular Genetics

We are conducting research on the mechanism by which various plant functions, including photosynthesis, are optimized in response to changes in the environment, using various cutting-edge technologies centered on the analysis of mutant strains.

Plant Systematics

We are working on the evolution and diversity of wild plants from various perspectives and approaches, taking advantage of both field research and laboratory experiments.

Cooperation Course

Ecological Science II

We aim to understand the interaction between living things or between living things and the environment, focusing on plants, by making full use of field research, manipulation experiments, molecular genetic methods, theoretical methods, and other methods.
