TL;DR: The development and constitution of the inclusion bodies induced by Italian and Californian isolates of cauliflower mosaic virus was studied by light and electron microscopy and suggests that they are sites of virus synthesis and/or assembly.
Abstract: Summary
The development and constitution of the inclusion bodies induced by Italian and Californian isolates of cauliflower mosaic virus was studied by light and electron microscopy. Cytochemical and enzyme-digestion tests revealed that the inclusion bodies are essentially proteinaceous, and contain RNA and some DNA. These inclusions have a matrix composed of densely packed, finely granular or fibrillar material and vacuole-like areas not bounded by a membrane. Virus particles are interspersed at random with the matrix and are not aggregated in regular crystalline arrays. The developmental sequence of the inclusions suggests that they are not merely structures for virus accumulation but, rather, that they are sites of virus synthesis and/or assembly.

TL;DR: Examination of the physical structure of cauliflower mosaic virus DNA by electron microscopy and ultracentrifugal analysis showed that the DNA could be isolated mainly as a circular molecule of mol.
Abstract: Summary Examination of the physical structure of cauliflower mosaic virus DNA by electron microscopy and ultracentrifugal analysis showed that the DNA could be isolated mainly as a circular molecule of mol. wt. 4.7 × 106. Nearest-neighbour frequency analysis showed that the DNA has a chemical structure which exhibits close similarities to that of the host cauliflower DNA. The relationships of this plant virus DNA and the small mammalian virus DNAs to the DNA of their respective hosts are discussed.
