Eight vRNPs within a virion. (A) (Left) Transverse section of a budding virion (left side of A is reprinted from Noda et al. [2006] with permission from the authors); (right) three-dimensional model of eight vRNPs within a virion reconstructed by electron tomography (right side of A is reprinted from Noda et al. [2012] under a Creative Commons Attribution-NonCommercial-Share Alike 3.0 Unported License). Each of the eight vRNPs is colored differently. (B) A single bundle of eight vRNPs arranged in a “1 + 7” pattern, in which some vRNPs align in antiparallel orientation, associates with the tip of the budding virion, even in huge filamentous virions. Note that only three vRNPs are depicted here for clarity.
