In experimentally infected 12-week-old plants, TMV penetrated all areas of mesophyll, parenchyma and root cells. Infection caused distortion of the chloroplasts leading to loss of membrane integrity. Electron opaque bodies proliferated within the chloroplasts, pressing against the outer membranes. TMV particles were visible in the cytoplasm and vacuoles, with dense ribosomal configurations in the cytoplasm making the organelles and cellular integrity quite different from non-infected tissue.
