Cytochemical characterization of plastidal inclusions in Abutilon mosaic-infected Malva parviflora mesophyll cells.
Electron microscopy of plastids from mesophyll cells of Malva parviflora infected with the Abutilon mosaic virus revealed elongated "chains of pearls" with subunits of 7.5 nm in diameter. Paracrystalline inclusions of the chains of pearls studied by means of cytochemical techniques gave evidence of the presence of DNA.
