Call for contributed talks and posters for symposium on "New Frontiers in Genome Diversity and Evolution: Exploring the 3D Organization and Function of Genomes" (Symposium 38) at ESEB 2025 The ESEB 2025 Congress will be held at the International Convention Centre of Barcelona (CCIB) in Barcelona, Spain, from August 17th to 22nd, 2025. Within this congress, we are excited to announce a symposium on the evolution of 3D genome organisation, and we invite you to submit an abstract for a talk or poster presentation. Symposium organisers are Aurora Ruiz-Herrara (Universitat Autonoma Barcelona), Thea Rogers (University of Vienna) and Rui Faria (University of Porto). Symposium description The study of genome structure and function across diverse phylogroups is key for our understanding of evolutionary dynamics and their role in speciation and the generation of biodiversity. In this context, the evolution of chromatin conformation is fundamental for deciphering the mechanisms underlying the origin and evolvability of genome architecture, opening new frontiers in comparative genomics and evolution. This rapidly accelerating research field is fueled by significant recent progress in genomic resources, including the generation of complete genomes. Consequently, this symposium will delve into a cutting-edge area of evolutionary biology, exploring the relationships between 3D genome organization and the evolution of novel genomic, recombination and regulatory patterns. It will provide a forum to discuss topics ranging from local regulatory architecture focusing on the intricate interactions between genes to large-scale genomic processes that can shape the evolution of regulatory regions. Topics will include, but are not limited to, large-scale genome rearrangements, transcriptional regulation through long-distance enhancer-promoter interactions and chromosome-scale phenomena such as meiosis and dosage compensation. The symposium will also cover functional and comparative genomics, examining the conservation and divergence of genome topology across species. This comparative approach will shed light on the distinct evolutionary trajectories of lineages and offer valuable insights into the genetic underpinnings of species' adaptation and innovation. We have two exciting invited speakers presenting at this symposium, Claire Mérot, University of Rennes (France), and Harris Lewin, Arizona State University (USA).
