| Abstract: | Abstract The alterations caused by GFV in the leaves and roots of Vitis vinifera, and in the leaves of Nicotiana clevelandii and Chenopodium amaranticolor were studied in the electron microscope. In Nicotiana and Vitis, the main alterations were found in the chloroplasts, while in Chenopodium they were found in the cytoplasm. In all cases, the tonoplast appeared more electron opaque than normal and showed irregular densities over its surface. The presence of virus-like particles was demonstrated only in two cases. |
