Differentiating PVY(NTN) from PVY(N) by annealing to reference RNA transcripts.

Abstract excerpt

A method for the differentiation of virus strains based on the shift in electrophoretic mobility of partially annealed RNA transcripts is described. Oppositely oriented RNA transcripts of the NTN- and N-strains of PVY, complementary at their 3'-end variable (strain-specific) region, were annealed to form a partial duplex which moved more slowly in gel than heterologous (NTN+N) unpaired transcripts. Thus, the two...
