Some Properties of Potato Mop-Top Virus and its Serological Relationship to Tobacco Mosaic Virus

Evolutionary features of 8K (KDa) silencing suppressor protein of Potato mop-top virus

The cysteine-rich 8K protein of Potato mop-top virus (PMTV) suppresses host RNA silencing. In this study, evolutionary analysisof 8K sequences of PMTV isolates was studied on the basis of nucleotide and amino acid sequences. Twenty-one positively selected sites were identified in 8K codingregions. Recombination events were found in the 8K of PMTV isolates with a rate of 1.8. Totally 30 haplotyp...

Detection of potato mop-top virus capsid readthrough protein in virus particles.

Potato mop-top furovirus (PMTV) RNA 3 encodes the 20 kDa coat protein and a larger readthrough protein of 67 kDa. The readthrough protein is expressed by suppression of the amber stop codon which terminates the coat protein gene. A 21 kDa C-terminal fragment of the readthrough protein was doned, fused to glutathione S-transferase and expressed in E. coli. An antiserum prepared against purified ...

Effect of Potato Virus Y and Tobacco Mosaic Virus on Field - Grown Burley Tobacco

SIEVERT, R. C. 1978. Effect of potato virus Y and tobacco mosaic virus on field-grown burley tobacco. Phytopathology 68: 823-825. Yield, grade index, crop index, value per kilogram, and tobacco had less nicotine and TMV-infected tobacco had less value per hectare were reduced when Burley 37 became a-amino nitrogen, but tobacco infected with TMV+PVY had infected with tobacco mosaic virus (TMV), ...

The iron content of tobacco mosaic virus and some properties of its infectious nucleic acid.

llvidence for the occurrence of iron and certain other trace elements in purified preparations of tobacco mosaic virus has been presented by Loring and Waritz (1). A considerable variation in the iron content of the virus was found under different conditions, but in no case in which virus activity was retained was it possible to reduce the iron content to less than approximately 20 pg. per gm. ...
