Differential pathogenicity of two different recombinant PVY(NTN) isolates in Physalis floridana is likely determined by the coat protein gene.

ABSTRACT: A previous study has identified two types of recombinant variants of Potato virus Y strain NTN (PVY(NTN)) in China and sequenced the complete genome of the variant PVY(NTN)-HN2. In this study, the complete genome of isolate PVY(NTN)-HN1 was fully sequenced and analyzed. The most striking difference between the two variants was the location of recombinant joint three (RJ3). In PVY(NTN)-HN1, like other typical European-PVY(NTN) isolates such as PVY(NTN)-Hun, the RJ3 was located at nucleotide (nt) 9183, namely the 3' proximal end of the CP gene (nt. 8571-9371), thus leading to most (the first 613 nucleotides from the 5' proximal end) of the CP gene (801 bp) with a PVYN origin and PVYN-serotype; whereas in contrast, the RJ3 in PVY(NTN)-HN2 was located at nt 8572, consequently leading to a CP g
