Overview

Potato virus S (PVS) (genus Carlavirus , family Betaflexiviridae ) is one of the most prevalent viruses in potato crops ( Solanum tuberosum and S. phureja ) around the world, causing reductions in crop yields between 10 and 20 %. Symptoms of PVS infection may include leaf mottling, rugosity of leaves, deepening of the veins and reductions in crop yields between 10 and 20 %. Virions are flexuous rods of 610-710 nm with a positive-sense ssRNA genome of approximately 8500 nt comprising six ORFs, a 5′CAP and a 3′poly-A tail. PVS has been classified into two groups: PVS O (Ordinary) and PVS A (Andean). PVSA induces severe symptoms in infected plants, such as premature senescence and defoliation, and is more efficiently transmitted by aphids than PVS O . To date, only five PVS genomes have been completely sequenced, including those of three PVS O and two PVS A strains. Currently, there are no reports of complete PVS genome sequences from Andean South America. In this work, we present the complete genomic sequence of a novel PVS strain infecting S. phureja that is clearly distinct from currently known PVS isolates.
