Structural studies on the polyhedral inclusion bodies, virions, and DNA of the nuclear polyhedrosis virus of the cotton bollworm Heliothis zea

D W Scharnhorst et al. J Virol. 1977 Jan.

Abstract

The polyhedral inclusion body of the cotton bollworm nuclear polyhedrosis virus contains virions occluded in an orthogonal crystalline matrix. The virions appear as rods or, more frequently, as oval structures that form upon bending of the nucleocapsid within the viral membrane. The nucleocapsid consists at least of DNA surrounded by a capsid composed of subunits, possibly helically arranged. The viral DNA is circular and supercoiled. It is heterogenous in size with contour lengths ranging from 15 to 45 mum.
