[S02]Symposium 02 National Bioresources for Developmental Biology: Birds and Amphibians Meet Flowers and Bryophytes

Tue. Jun 9, 2026 3:00 PM - 6:00 PM JST
Tue. Jun 9, 2026 6:00 AM - 9:00 AM UTC
Room B = Multi-purpose studio (2F)(JMS ASTERPLAZA 2F)
Chairpersons:Hajime ogino(Hiroshima Univ.), Toshinori Hayashi(Hiroshima Univ.)
Co-organized by NBRP Clawed frogs & Newts, NBRP Chrysanthemums, NBRP Chickens & Quails

The aim of developmental biology is to elucidate the mechanisms underlying the morphogenesis of a variety of organisms. Achieving this goal requires the use of diverse organisms with distinct characteristics, enabling researchers to identify both the commonalities and differences in their developmental processes, and to uncover the cellular behaviors and gene regulatory networks that drive them. Traditionally, research communities have tended to specialize within individual model organisms, deepening knowledge within each species. However, recent advances in genomic information and related resources have made it possible to conduct comparative studies across distantly related taxa-an approach once considered unattainableand these comparisons have led to numerous breakthroughs.
Central to such interspecies comparative research are high-quality biological resources. Hiroshima University, which hosts the Organizing Committee of the 59th Annual Meeting of JSDB, operates multiple bioresource programs that encompass a wide range of species, from animals to plants. This symposium aims to explore emerging directions in next-generation research through presentations by directors of these bioresource projects, as well as researchers who actively utilize them.
