| Outline of Final Research Achievements |
In eukaryote cells, communication between organelles is crucial for the cellular homeostasis. Since nuclear genome has most of genetic information in the cell, it is often considered the organelles are slaves of the nucleus. However, organelles such as plastid, which are endosynbiotic origin and have a small genome, transmit signals to the nucleus to control wide variety of cellular function. Our research aim is understanding the signal transduction pathway from chloroplasts to the nucleus (plastid signaling) using Arabidopsis and Marchantia. We isolated new class of plastid signaling mutants using FOX hunting screening. We found GBF1 and TCTP has genetic interaction with previously reported GUN genes.
