[Electron-microscopic study of potato aucuba mosaic virus].

The results of electron-microscopic investigation of the peculiarities of virus interrelations with cells of mesophyl of the potato leaves, which were infected with potato aucuba mosaic virus (PAMV) are presented. Aggregates of the virus particles have been revealed which are localized in cytoplasm between the cellular organoids and just near the cellular membrane. The significant destructural changes of the structure of chloroplasts and formations of virus-induced inclusions in them are observed. The cells contain cytoplasmic inclusions--round and oval electron-dence formations which are surrounded with a friable membrane. They occupy the large zones of cytoplasm, that is a typical sign of PAMV infection.
