| sequence of morphological alterations in blue-green algae in the course of cyanophage infection. | electron microscopic studies were performed on the sequence of morphological alterations induced by the cyanophage pp-1 in the blue-green algae phormidium sp. and plectonema boryanum. the following phases of virus infection were made evident: virus adsorption onto the host cell; the presence of virus "ghosts", suggesting the penetration of viral dna into the cell and its multiplication in the nucleoplasm; invagination of thylakoids and formation of the "virogenic stroma"; virus maturation within ... | 1981 | 6787795 |
