► (+)RNA viruses use conserved mechanisms to build membranous replication complexes. ► Virtually all (+)RNA viruses actively modify lipid synthesis. ► Secretory pathway components contribute to replication of many (+)RNA viruses. ► Hijacked host factors are integrated into networks not found in uninfected cells. ► Membrane composition of replication organelles differs from pre-existing membranes. Positive-strand RNA [(+)RNA] viruses show a significant degree of conservation of their mechanisms of replication. The universal requirement of (+)RNA viruses for cellular membranes for genome replication, and the formation of membranous replication organelles with similar architecture, suggest that they target essential control mechanisms of membrane metabolism conserved among eukaryotes. Recently, significant progress has been made in understanding the role of key host factors and pathways that are hijacked for the development of replication organelles. In addition, electron tomography studies have shed new light on their ultrastructure. Collectively, these studies reveal an unexpected complexity of the spatial organization of the replication membranes and suggest that (+)RNA viruses actively change cellular membrane composition to build their replication organelles.
