[3MS-11]【J】Understanding the molecular mechanisms of microbial gene expression in natural environments

Fri. Dec 5, 2025 11:15 AM - 12:35 PM JST
Fri. Dec 5, 2025 2:15 AM - 3:35 AM UTC
Room 11(Pacifico Yokohama Conference Center 4F, 414+415)
Organizer: Tomohiro Shimada (Meiji University), Hiroshi Ogasawara (Shinshu University)
Traditionally, microorganisms have been studied in the laboratory as model organisms to understand cellular molecular mechanisms. It is now known that a wide variety of microorganisms exist in a wide variety of natural environments, and understanding their molecular mechanisms is a challenge for current science. In this symposium, we would like to discuss research aimed at understanding the molecular mechanisms, mainly gene expression, of survival strategies of microorganisms in natural environments such as soil and rivers, and in symbiosis and infection among heterologous bacteria and with plants and animals.
