Processing of the tobacco etch virus 49K protease requires autoproteolysis
Virology, 1987The final products encoded by the tobacco etch virus genome arise by proteolytic cleavage of a single large polyprotein precursor. Processing of the polyprotein at several sites requires the activity of a viral protease of 49,000 molecular weight (49K).

Exploring the activity of tobacco etch virus protease in detergent solutions
Analytical Biochemistry, 2008Tobacco etch virus (TEV) protease is generally used to remove affinity tags from target proteins. It has been reported that some detergents inhibit the activity of this protease, and therefore should be avoided when removing affinity tags from membrane proteins. The aim of this study was to explore and evaluate this further. Hence, affinity tag removal

Tobacco etch is one of the most widespread and injurious viruses on burley tobacco in Ontario. Three strains of this virus were obtained from tobacco collections. Their symptoms and behavior on tobacco and other hosts are described. Tobacco varieties were divided into two groups on the basis of their reaction to the etch virus.

Physiology of tobacco etch virus-induced wilt of Tabasco peppers
Virology, 1967Abstract A change in permeability, indicated by a release of sodium and potassium ions, was detected in the roots of tobacco etch virus (TEV)-infected Tabasco pepper plants 24–48 hours before wilt symptoms occurred. The permeability change also preceded a decrease in the respiratory rate by 12–24 hours, and histological changes by 24–48 hours.

Structural characterization of Tobacco etch virus coat protein mutants
Archives of Virology, 2003The assembly of Tobacco etch potyvirus (TEV) coat protein (CP) and truncated mutants in Escherichia coli was studied. CP from which 28, 63 or 112 amino acids were deleted from the N-terminus polymerized into potyvirus-like particles (PVLPs). These structures were more rigid and progressively smaller in diameter than those produced by full length TEV-CP.

Topographic analysis of tobacco etch virus capsid protein epitopes
Virology, 1985Monoclonal antibodies have been prepared, which react with capsid protein of an aphid-transmitted isolate of tobacco etch virus (TEV). Ten different monoclonal antibodies were characterized with reference to (1) antibody class, (2) reactivity with different plant virus antigens, (3) the spatial relationship between epitopes, and (4) whether these ...

Virology, 1992
Transgenic tobacco plants which express untranslatable sense or antisense forms of the tobacco etch virus potyvirus (TEV) coat protein (CP) gene sequence have been generated. One of seven transgenic plant lines expressing a CP gene antisense transcript showed an attenuation of symptoms when inoculated with TEV.

Burley tobacco is susceptible to several different types of virus diseases that suppress plant growth and development. Two viruses, tobacco etch virus (TEV) and tobacco vein mottling virus (TVMV), are particularly damaging to burley. Burley tobacco cultivars resistant to these two viruses are currently being developed. Some of these cultivars also show

Biochemical effects of tobacco etch virus infection on tobacco leaf tissue—I.
Phytochemistry, 1966Abstract Intact chloroplasts isolated from leaf tissue of Nicotiana tabacum L. systemically infected with tobacco etch virus incorporated glycine-1,2- 14 C into a TCA insoluble product at the same rate as did chloroplasts from healthy plants. Tissue from infected plants, however, contained only about two thirds as many chloroplasts on a fresh ...
