Complete genome sequence of a novel Potato virus S strain infecting Solanum phureja in Colombia
Archives of Virology 158 (10), 2205-2208
Abstract: 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: PVSO (Ordinary) and PVSA (Andean). PVSA induces severe symptoms in infected plants, such as premature senescence and defoliation, and is more efficiently transmitted by aphids than PVSO. To date, only five PVS genomes have been completely sequenced, including those of three PVSO and two PVSA 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.
