Abstract:
Transcriptome analysis of a Cape gooseberry (Physalis peruviana) plant with leaf symptoms of a mild yellow mosaic typical of a viral disease revealed an infection with Potato virus X (PVX). The genome sequence of the PVX-Physalis isolate comprises 6435 nt and exhibits higher sequence similarity to members of the Eurasian group of PVX (~95 %) than to the American group (~77 %). Genome organization is similar to other PVX isolates with five open reading frames coding for proteins RdRp, TGBp1, TGBp2, TGBp3, and CP. 5′ and 3′ untranslated regions revealed all regulatory motifs typically found in PVX isolates. The PVX-Physalis genome is the only complete sequence available for a Potexvirus in Colombia and is a new addition to the restricted number of available sequences of PVX isolates infecting plant species different to potato.
