From: Bombyx mori nucleopolyhedrovirus (BmNPV) Bm64 is required for BV production and per os infection
TEM analysis. BmN cells were transfected with vBm (a, d, and g), vBm64KO (b, e, and h), or vBm64RE (c, f, and i), and at 72Â h p.i. the cells were analyzed by TEM. Panels a -c show whole cell low magnification micrographs displaying enlarged nuclei (Nu), virogenic stroma (vs), and polyhedra (P). Panels (d, e, and f) show higher magnification micrographs of polyhedra and the production of ODV (arrows). Panels (g, h, and i) compare nucleocapsids (arrows) and the association of nucleocapsids with virus-induced nuclear microvesicles (triangles). C, cytoplasm; nm, nuclear membrane; cm, cytoplasm membrane
