The lab studies how plants sense environmental stimuli and use that information to build tissues.
AboutAbout the lab
Unraveling how plants form tissues at the molecular level
The Plant Pattern Formation Lab studies how plants sense external stimuli and use that information to build tissues.
Because plants cannot move, they have developed the ability to cope with environmental stresses such as temperature fluctuations and drought.
At the molecular level, the lab investigates the key factors in signal transduction in response to environmental stress, as well as the mechanisms that form and maintain the stem cells supporting the growth of roots, stems, and leaves.
On the lab's website, the lab is introduced under the name "Torii Group."
Key terms
- Signal transduction
- The mechanism by which plants sense external information and, through signaling molecules, link it to the regulation of organ formation
- Signaling molecules
- Substances that plants produce when they sense external information. They convey the information needed for self-defense and growth
- Stem cells
- Cells capable of producing new cells. They support plant growth and the repair of damaged parts
ResearchResearch themes
The lab aims to gain a comprehensive understanding of how plants sense external stimuli and use that information to form tissues. It approaches this from two sides: signal transduction in response to environmental stress, and the regulation of the formation and maintenance of plant stem cells.
*Illustrative imageSignal transduction in response to environmental stress
It has been suggested that plants sense external information and produce signaling molecules, which convey the information needed for self-defense and growth and thereby control organ formation. The lab investigates the molecular mechanisms and physiological functions of the key factors in this signaling.
*Illustrative imageRegulation of the formation and maintenance of plant stem cells
Focusing on the stem cells that support the growth of roots, stems, and leaves and the repair of damaged parts, the lab investigates how the genes of the key factors for their formation are regulated and how these factors interact with one another. It also studies which surrounding stimuli activate these factors.
MembersFaculty
The members of the Plant Pattern Formation Lab consist of the principal investigator, co-PIs, collaborating researchers, postdoctoral researchers, technicians, technical assistants, and secretaries.
