Chief Scientist Laboratories Plant Epigenome Regulation Laboratory
Chief Scientist: Motoaki Seki (Ph.D.)
Research Summary
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.
