electron microscopy of leaves infected with sowbane mosaic virus and other small polyhedral viruses. | leaves of chenopodium amaranticolor were infected with sowbane mosaic virus (smv), sectioned and examined by electron microscopy. leaves of brassica pekinensis and c. amaranticolor were infected with turnip yellow mosaic virus and cowpea mosaic virus, respectively, and similarly studied. with all three viruses it was difficult, in sections, to distinguish the small isometric virus particles from ribosomes though sometimes this was possible, especially when the viruses crystallized. pretreatment ... | 1967 | 18614059 |
