Takahashi Lab
Machine-translated · View original
A lab that investigates how plants respond to environmental stress at the gene level.
AboutAbout the lab
Exploring stress tolerance through communication between organs
Takahashi Lab studies, at the level of genes, how plants respond to environmental stresses such as drought and high temperature.
In particular, it focuses on long-distance signaling, in which environmental information is shared and integrated between distant organs such as roots and leaves, and it searches for and analyzes the regulatory factors and signaling factors that control this process.
Building on these results, the lab is also developing stress-tolerant crops that can grow in harsh environments and help address food and environmental problems.
Key terms
- long-distance signaling
- A mechanism by which environmental information is transmitted and shared between distant organs, such as roots and leaves
- abscisic acid (ABA)
- A plant hormone. It is synthesized in the leaf vascular tissue of plants that sense drought stress, and it leads to drought tolerance
- transcription factor
- A protein that regulates gene expression. NGA1 regulates the expression of an ABA synthesis enzyme

ResearchResearch themes
The lab aims to uncover, at the gene level, how plants respond to environmental stress, and to apply this to developing stress-tolerant crops. It focuses in particular on inter-organ communication, in which environmental information is shared and integrated between distant organs such as roots and leaves.
*Illustrative imageTransmitting drought stress signals between roots and leaves
In 2018, Prof. Takahashi and colleagues showed that the CLE25 peptide, secreted from the vascular tissue of roots, is the mobile molecule that carries drought stress information from roots to leaves. The lab is working to elucidate how information is transmitted and shared between roots and leaves through the secretion of small molecules, including CLE25.
*Illustrative imageSignals that control ABA synthesis
Plants that sense drought stress synthesize the plant hormone abscisic acid (ABA) in the vascular tissue of their leaves and gain drought tolerance. In 2018, Prof. Takahashi and colleagues identified the transcription factor NGA1, which regulates the expression of an ABA synthesis enzyme, and reported its function. The lab is now working to elucidate the mechanism that regulates NGA1 expression.
*Illustrative imageSignal transduction in the high-temperature stress response
Rice is one of the most important food crops for people around the world, but the high temperatures that accompany global warming stunt its growth and reduce yields, creating a need for rice that tolerates heat. Focusing on heat-tolerant varieties, the lab investigates how high-temperature stress is sensed and how signals are transmitted inside cells.
*Illustrative imageDeveloping stress-tolerant crops
To create crops that can grow in harsh environments and help address food and environmental problems, it is important to make use of research results obtained in model plants. Focusing on genes, peptides, and metabolites involved in stress responses, the lab is developing tolerant crops in rice and tomato.
