Aggregates of up to 20 chloroplasts occur in parenchyma cells from local lesions induced in Chenopodium quinoa Wild. by turnip mosaic virus. Electron microscopic examination revealed a single layer of virus particles parallel to the surface of chloroplasts between most of the aggregated chloroplasts.
