Symposium

[3AS-06]【E】Coordination between nucleoid structure and metabolism in bacteria and organelles

Fri. Dec 5, 2025 9:00 AM - 11:00 AM JST
Fri. Dec 5, 2025 12:00 AM - 2:00 AM UTC
Room 6(Pacifico Yokohama Conference Center 3F, 311+312)
Organizer: Kazutoshi Kasho (Kyushu University), Taku Oshima (Toyama Prefectural University)
Mitochondria and chloroplasts are important organelles for cellular metabolism and energy production. Recent studies have revealed that their unique circular genomes, as well as prokaryotic ones, form non-chromatinized 'nucleoid' structures, and play regualtory roles in DNA replication, gene expression, and homeostasis. This symposium will bring together nucleoid research from various organisms to elucidate common principles.
