A point mutation in the coat protein abolishes aphid transmissibility of a potyvirus.

Virology - 1 Sept 1990

Atreya C D, Raccah B, Pirone T P

Abstract excerpt

A nonaphid transmissible (NAT) variant of tobacco vein mottling virus (TVMV) was used to test the hypothesis that the viral coat protein (CP) plays a role in determining aphid transmissibility. Comparison of the nucleotide sequences in the coat protein cistron of an aphid transmissible isolate (TVMV-AT) with that of TVMV-NAT revealed a single nucleotide difference (G----A) at position 8445; this alters a single...
