The Relation of Tobacco Mosaic Virus X-Protein to Amorphous Cellular Inclusions (X-Bodies). A. L.

Two common (U-1[D] and U-1[SB]) strains of tobacco mosaic virus and U-5 were used to determine whether the frequency of amorphous intracellular inclusions (X-bodies) correlated with extractable X-protein. Although U-1(SB) produced more X-bodies than U-1(D), no consistent differences were found between these common isolates in X-protein yields. The U-5 strain produced X-bodies only rarely, and yielded no X-protein.
