Protein composition of unusual tobacco mosaic virus strains. 1975

J R Dawson, and M W Rees, and M N Short

Amino acid analyses have been made of the proteins of single-lesion isolates of five strains of tobacco mosaic virus (TMV) differentiated by Lycopersicon hosts. These hosts differed in their genetical control of resistance to TMV, and the virus strains had therefore survived specific selection pressures. Two of the five strains differed in their amino acid composition from type TMV and from all other tomato strains of TMV previously examined. Symptoms induced by the five strains in four tomato lines and in Nicotiana tabacum cvs White Burley and Kawala are described.

UI	MeSH Term	Description	Entries
D000596	Amino Acids	Organic compounds that generally contain an amino (-NH2) and a carboxyl (-COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins.	Amino Acid,Acid, Amino,Acids, Amino
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
