Pelargonium Leaf Curl Virus in Host Leaf Tissues

Istituto di Patologia vegetale, Università degli Studi, Bari, Italy

The cytopathology of Pelargonium leaf tissues infected by an Italian isolate of the leaf curl virus (PLCV) was studied with the electron microscope. Virus particles were found in both parenchyma cells and conducting elements either irregularly scattered or in crystalline arrays. Clusters of virus particles were often seen within vesicle-like cytoplasmic extrusions protruding into the central vacuole. Cellular organelles were much damaged and internally disorganized. A peculiar budding condition of chloroplasts was observed. Virus particles were associated with nuclei and chloroplasts. In the latter, groups of particles not surrounded by visible membranes occurred apparently free in the plastidial stroma and in the buds developing from chloroplasts. The significance of the various pathological features is discussed.
