Auxin is a class of plant hormones, which is widely distributed in the plant kingdom. Auxin plays an essential role in almost all aspects of plant growth and development. We recently elucidated the major pathway of auxin biosynthesis, and we are currently studying on the regulatory mechanism of this pathway. 


In this laboratory, you can study exciting scientific questions in plant science, to which nobody knows the answers. Sometimes you may face the difficulties, but I hope that you enjoy and overcome them together with the laboratory members. Please feel free to contact and visit us!
