title: [Cytopathology of plants infected with viruses. Ultrastructure of leguminous leaves infected with red clover mottle virus].
abstract: We studied ultrathin sections of clover, pea, and cowpea leaves from intact plants and after infection by red clover mottle virus (RCMV, comovirus, 28 nm isometric virions) under an electron microscope. Significant pathological changes were observed in the leaf cells after the infection: RCMV virions accumulated in the cytoplasm and vacuoles, tubular structures containing the virion-like particles, as well as vesicular aggregates were observed. Large membrane-containing inclusions with long tubules (approximately 35 nm in diameter) were found in the cytoplasm of the infected clover chlorenchyma cells. Apparently, these novel inclusions correspond to virus-induced protein synthesis.
