AboutAbout the lab
Unraveling the mechanisms that support plant growth and survival at the molecular, cellular, and tissue levels
The Plant Cell Function Lab studies the mechanisms that support plant growth and survival at the molecular, cellular, and tissue levels.
The Ueguchi Group uses Arabidopsis thaliana to study the shoot apical meristem, which maintains stem cells while producing cells that become leaves and flower buds.
The Takeda Group mainly uses rice to study, among other topics, how the function of the growing point is maintained under environmental stress.
Key terms
- Shoot apical meristem
- A tissue that maintains undifferentiated stem cells while supplying cells that, through cell division, become leaves and flower buds. Abbreviated as SAM.
- Membraneless organelle
- A compartment inside a cell that is not enclosed by a membrane and is formed when proteins and other molecules gather together.

ResearchResearch themes
The lab aims to unravel the mechanisms that support plant growth and survival at the molecular, cellular, and tissue levels. The Ueguchi Group studies the shoot apical meristem, and the Takeda Group studies the maintenance of growing points under environmental stress in rice, as well as membraneless organelles.
*Illustrative imageMaintaining shoot apical meristem function
Using Arabidopsis thaliana, the lab studies the shoot apical meristem, which maintains undifferentiated stem cells while supplying cells that become leaves and flower buds. Using mutants, the lab explores how this function is maintained.
*Illustrative imageRice growing points and membraneless organelles
Mainly using rice, the lab studies how growing-point function is maintained under environmental stress and how the response to jasmonic acid is regulated. The lab is also working on artificially creating membraneless organelles inside plant cells.
