Changes in Non-protein Nitrogen Metabolism during Tobacco Mosaic Virus Biosynthesis
1. Discs cut from tobacco leaf tissue infected with tobacco mosaic virus and cultured in water contain less non-protein nitrogen than comparable uninfected discs during the time at which TMV is formed. This deficiency disappears when virus formation ceases. Discs cultured in nutrient solution form about twice as much TMV as discs cultured in water. The maximum non-protein nitrogen deficiency is...
متن کاملRelationships between Tobacco Mosaic Virus Biosynthesis and the Nitrogen Metabolism of the Host
1. Comparisons of the nitrogen content of TMV-infected and uninfected tobacco leaf discs at various times after inoculation show that virus synthesis is associated with a net increase in protein content. This excess protein is due to: (a) TMV, (b) an excess in insoluble protein which develops soon after inoculation and ends about 100 hours before cessation of TMV synthesis, and (c) an excess in...
متن کاملRelationships between Tobacco Mosaic Virus and the Non-virus Proteins
1. The non-virus proteins, A4, B3, and B6, characteristically found in tobacco leaf infected with TMV exhibit specific immunochemical cross-reactions with serum prepared against the virus. The close immunochemical relations which occur among these proteins do not extend to any normal tobacco leaf proteins. 2. The rate of appearance of the non-virus proteins in newly infected cultured leaf tissu...
متن کاملThe Non-virus Proteins Associated with Tobacco Mosaic Virus
1. Exhaustive fractionation of leaves from tobacco plants systemically infected with TMV has led to the isolation of two non-virus proteins, B3 and B6, and the detection of a third, A4, which do not occur in comparable uninfected plants. 2. Components B3 and B6 have been found consistently in a series of ten extracts from plants grown over an 18 month period in all seasons of the year. It is co...
متن کاملMovement of a barley stripe mosaic virus chimera with a tobacco mosaic virus movement protein.
The tobacco mosaic virus (TMV) 30K movement protein (MP) gene was inserted into a full-length cDNA clone of barley stripe mosaic virus (BSMV) RNA beta replacing the triple gene block (TGB). The resulting recombinant ND-MPT genome, consisting of infectious wt transcripts of BSMV RNAs alpha and gamma, together with the hybrid RNA beta transcript, was inoculated onto test plants to study the funct...
