Cauliflower mosaic virus in the nucleus of Nicotiana.
An isolate of cauliflower mosaic virus that occurs in nuclei of Nicotiana is reported. Affected nuclei become greatly enlarged and filled with virions without the electron-dense matrix material characteristic of cytoplasmic sites of virus assembly. Conventional cytoplasmic inclusions with embedded virus occurred in other cells of the same tissue.
