[2AS-16]【J】Genomic imprinting redefinition and associated examples: Evolution of the epigenomic regulation system and conflict theory

Thu. Nov 28, 2024 9:00 AM - 11:15 AM JST
Thu. Nov 28, 2024 12:00 AM - 2:15 AM UTC
Room 16(Marine Messe Fukuoka Hall B, 2F Meeting Room 2-1)
Organizer: Hisato Kobayashi (Nara Medical University), Yuko Wada (Nara Institute of Science and Technology)
The year 2024 commemorates the 40th anniversary of the discovery of the "mammalian genome imprinting mechanism" through mouse nuclear transfer experiments. During this symposium, we will present the forefront of genome imprinting research across a diverse range of organisms. We will also explore topics such as the diversification of genomic imprinting mechanisms in speciation and their role in species evolution, the examination of the conflict hypothesis, and the prospects for future research in this field.
