The complete nucleotide sequence of tobacco necrosis virus strain D.
The complete sequence of the RNA genome of tobacco necrosis virus strain D (TNV-D) consisting of 3759 nucleotides has been determined. The positive strand contains five open reading frames (ORFs). The 5'-proximal ORF encodes a 22K protein terminating with an amber codon which may be read through to produce a 82K protein (p82). Two small centrally located ORFs each encode two out-of-frame 7K pro...
متن کاملDark reactivation of ultraviolet-irradiated tobacco necrosis virus.
Some damage caused in tobacco necrosis virus by u.v. radiation could be repaired in darkness in Chenopodium amaranticolor (dark reactivation) but not in French bean or in tobacco. By contrast, photoreactivation of the irradiated virus was observed in French bean and in tobacco but not in Chenopodium. The kind of damage in u.v.-irradiated virus that is susceptible to repair by photoreactivation ...
متن کاملInvestigations on the Tobacco Necrosis Virus D p60 Replicase Protein
Tobacco Necrosis Virus D (TNV-D), in the genus Betanecrovirus (family Tombusviridae), possesses a single-stranded, positive-sense RNA genome containing six open reading frames (ORFs). Two 5'-proximal ORFs (1 and 2) encode overlapping polypeptides of 22 and 82 kDa (p22 and p82, respectively) which are both required for replication. The p22 auxiliary protein contains no replication motifs but the...
متن کاملInfection of tobacco mesophyll protoplasts by tobacco mosaic virus.
It was proved that the protoplasts prepared from mesophyll of Nicotiana tabacum are infected by tobacco mosaic virus. The infection occurred when purified tobacco mosaic virus particles were added to a protoplast suspension in the presence of poly-L-ornithine. The virus multiplied in these protoplasts to a level of 10(6) virus particles per infected protoplast during 24 hours of incubation. The...
متن کاملActivation of factor XII by tobacco glycoprotein
A glycoprotein of mol wt ca. 18,000 daltons isolated from cured tobacco leaves (TGP-L) and from cigarette smoke condensate (TGP-CSC) activated factor XII in normal human plasma in vitro as measured by (a) shortening of the partial thromboplastin time, (b) shortening of the lysis time of euglobulin clots, and (c) generation of kinin activity. These effects were not demonstrable in plasma deficie...
