Morphological and physical properties of a multiploid-forming mutant of Western equine encephalitis virus were studied. Electron micrographs of the infected cells showed that most of mutant virions bud from the plasma or vacuolar membrane as a multiploid particle containing a various number of nucleocapsids enclosed with a defined common envelope. The mutant virions contained three polypeptides which migrated to the position identical with those of wild type on discontinuous acrylamide gels. Cells infected with the mutant virus synthesized the same intracellular viral RNA species as was made after infection of wild type. Cytoplasmic nucleocapsids of the mutant sedimented at 140S and contained 42S virion RNA as those of wild type; they were indistinguishable from those of wild type in an electron microscope examination. On the other hand, mutant nucleocapsids isolated from extracellular virions sedimented as heterogeneous particles larger thant 140S and were shown to be pleomorphic and aggregate in electron micrographs. The budding process of this mutant seemed to be modified, so that it might form the multiploid with the alteration of its nucleocapsids.
