Morphology and intracellular appearance of Euonymus vein clear virus

Chang, M.U. (Youngnam Univ., Kyongsan (Korea R.))
Negatively stained dip preparations from Euonymus showing vein clear symptoms revealed bacilliform particles. The particles tentatively referred to as the Euonymus vein clear virus (EVCV) have a relatively complex structure, measuring 230-280nm in length and 70-80nm in diameter. They have an envelope, 8-10nm thick, provided with evenly spaced beadlike projection about 5 - 6 nm long. The inner tubular core which had no envelope showed helical structures, 200 - 220 nm long, and 50 - 55 nm in diameter. This inner tubular core was interpreted as the virus nucleocapsid. A striking association of virus particles with the nuclei of infected cells was apparent from sections which showed numerous virus particles at the nuclear periphery and in what appeared to be intranuclear virus particle inclusions
