Summary[edit]

Description
English: Intranuclear assembly of Oryctes rhinoceros nudivirus (OrNV) virions. (A) A slice from FIB-SEM reconstruction of an infected cell. Scale bar, 2 μm. (A1) The nucleus is filled with long tubules (Tu) extending from chromatin-like structures (CLS). Clusters of new virions associated with Tu migrate toward the inner nuclear membrane (INM). The INM invaginates inside the nucleus (A2), engulfing fully assembled virions (A3). Scale bar, 500 nm. (B) TEM micrograph of an OrNV-infected cell displaying the mechanism of virion assembly and virion enwrapping in vesicles (scale bar, 1 μm). Tomographic reconstruction of the region shown in the inset. (B1) A 11-nm-thick section showing long filled tubules (fTu) and virion clusters being enveloped in membranes. Scale bar, 500 nm. (B2) Segmentation of the tomogram displaying viral capsids (red) inside filled tubules (gray) and membrane structures (blue).
