[Electron-microscopic study of potato aucuba mosaic virus]. 2007

O O Dmytruk, and O Ie Mamchur, and L P Kolomiiets

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.

UI MeSH Term Description Entries
D007181 Inclusion Bodies, Viral An area showing altered staining behavior in the nucleus or cytoplasm of a virus-infected cell. Some inclusion bodies represent "virus factories" in which viral nucleic acid or protein is being synthesized; others are merely artifacts of fixation and staining. One example, Negri bodies, are found in the cytoplasm or processes of nerve cells in animals that have died from rabies. Negri Bodies,Viral Inclusion Bodies,Negri Body,Bodies, Negri,Bodies, Viral Inclusion,Body, Negri,Body, Viral Inclusion,Inclusion Body, Viral,Viral Inclusion Body
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D011198 Solanum tuberosum A plant species of the genus SOLANUM, family SOLANACEAE. The starchy roots are used as food. SOLANINE is found in green parts. Potatoes,Potato,Solanum tuberosums,tuberosum, Solanum,tuberosums, Solanum
D015388 Organelles Specific particles of membrane-bound organized living substances present in eukaryotic cells, such as the MITOCHONDRIA; the GOLGI APPARATUS; ENDOPLASMIC RETICULUM; LYSOSOMES; PLASTIDS; and VACUOLES. Organelle
D017863 Potexvirus A genus of plant viruses in the family FLEXIVIRIDAE, that cause mosaic and ringspot symptoms. Transmission occurs mechanically. Potato virus X is the type species. Potato virus X,Potexviruses
D018515 Plant Leaves Expanded structures, usually green, of vascular plants, characteristically consisting of a bladelike expansion attached to a stem, and functioning as the principal organ of photosynthesis and transpiration.
