Chief Scientist: Motoaki Seki (Ph.D.)

Research Summary

Motoaki  Seki(Ph.D.)

Our laboratory aims to elucidate the molecular mechanisms of epigenome regulation networks in plant life cycle. To understand this topic involving histone modification and non-coding RNAs, we perform cutting-edge multidisciplinary approaches using model plants, including molecular biology, chemical biology and integrated omics analysis.
