Research Background |
Professor Jung have been investigating regulatory mechanisms that govern plant response to environmental changes majorly in temperature. The outstanding challenge in the temperature research is to identify the molecules that perceive temperature signals. As a postdoctoral researcher of Wigge group at University of Cambridge, he has discovered that a red-light photoreceptor phytochrome B (phyB) functions as a thermosensor in Arabidopsis (the first thermosensor identified in plants).
*Captured from the commentary on Jung et al. Science (2016)
Plant Biochemistry Lab (PBL), together with research groups in Germany, France, and UK, has recently reported that ELF3, a protein containing prion-like domains (PrDs) controls the plant’s temperature response by forming biomolecular condensates. ELF3 proteins reversibly forms liquid droplets in response to increasing temperature, in a PrD-dependent manner. This is the first study to show that the plant response to heat requires phase separation.
*Captured from the commentary on Jung et al. Nature (2020)
By exploiting new scientific concepts and the latest techniques, PBL aims to target the mechanisms by which plants control their growth and development in response to temperature changes. Our research will provide insights on our understanding how plants adapt to climate warming and will help us breed crop plants to be more resilient to increasing hot weather.
Major three target molecules
(1) Proteins containing intrinsically disordered region (IDR) or prion-related domain (PrD)
(2) RNA molecules interacting with thermosensory proteins
(3) Reactive oxygen species (ROS) to transmit temperature information

연구소개 |
To cope with global warming, a major issue affecting crop productivity, it is very important to understand how warm temperature affects plant flowering at molecular levels. Prion-like domain(PrD)-containing proteins, which are phase separated by heat, would be a key to understand thermosensory flowering in plants. Therefore, I aim to identify prion-like proteins responding to temperature changes and to understand how they form biological condensates for the thermal control of flowering. |
