Cryo-electron tomography reveals coupled flavivirus replication, budding and maturation

Selma Dahmane, Erin E. Schexnaydre, Jianguo Zhang…·Lars A. Carlson

Cryo-ET of Langat virus-infected cells shows replication organelle size set by a membrane coat plus RNA pressure, with virion budding and maturation occurring beside the organelles.
