Digest: Evolution of viral fitness is influenced by host genetic spatial structure.

Evolution; international journal of organic evolution - 8 Jul 2026

Casas Ares

Abstract excerpt

Host population dynamics influence viral evolution and host specialization. In a recent study, Visher et al. (2026) investigate the role of spatially structured host genotypes in the evolution of generalist and specialist viruses. Through experimentally evolving Plodia interpunctella granulovirus in inbred hosts of spatially clustered genotypes, the authors demonstrate that, even in heterogeneous populations,...
