Plant viruses come in two basic shapes: helical and polyhedral . Helical virus particles have an elongated shape and can be rigid rods or flexible filaments. Polyhedral virus particles are roughly spherical. The genetic material of a plant virus may be enclosed in one particle or split between two or more particles.
Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely ... Structure · Transmission · Translation of plant viral proteins |
Viruses consist of nucleic acid coated with protein; some may also contain lipid and other compounds. Fig. 4.1 shows something of the classification of plant ... |
10 мар. 2024 г. · New data on the structure of coat proteins, virions, and transport forms of helical plant viruses will allow understanding of the molecular ... |
Structurally, a significant part of plant virus particles is organized into flexible or rigid rod-shaped structures, while other viruses are isometric with ... |
Most or all flexible filamentous plant viruses share a common coat protein fold and helical symmetry, with slightly less than 9 subunits per helical turn. |
In this chapter the biochemical structure of plant viruses will be described, followed by an examination of virus morphology and architecture. |
