Host-shift adaptation shapes genome architecture in S. eubayanus

Pablo David Villarreal, Juan Ignacio Eizaguirre, Carlos A. Villarroel, Tomás A. Peña, Nicolas Agier, Christian I. Oporto, Valentina Abarca, Pablo A. Quintrel, Catalina Muñoz-Tapia, Felipe Muñoz-Guzmán, Quinn K. Langdon, Chris Todd Hittinger, Javier Echeverría, Roberto F. Nespolo, Gilles Fischer, , Francisco A. Cubillos

This study shows that host-shift adaptation in S. eubayanus leads to genomic changes, particularly structural variants, linked to sugar metabolism and host-specific traits.
