[1AS-09]【J】Growth and developmental strategies driven by "programmed stress" in eukaryotes

Wed. Dec 3, 2025 9:00 AM - 11:00 AM JST
Wed. Dec 3, 2025 12:00 AM - 2:00 AM UTC
Room 9(Pacifico Yokohama Conference Center 4F, 411+412)
Organizer: Misato Ohtani (The University of Tokyo), Yasuhiro Kamei (Kanazawa University)
Eukaryotes adjust their growth and development to environments via multilayered regulatory steps, such as transcriptional and post-transcriptional gene regulation and metabolism, then improve their fitness. Such growth strategies are sometimes species-specific; however, similar mechanisms can be found among phylogenetically distant species. Here, based on the talks from researchers using varied species as research materials, we will discuss the fundamentals of eukaryotic growth strategies, focusing on “programmed stress" as a core element of developmental and growth regulation deeply rooted in eukaryotes.
