Interpretive Summary: Pepino mosaic virus (PepMV) causes a devastating tomato disease worldwide. PepMV was initially isolated from pepino (Solanum muricatum), a tomato plant relative, in Peru during the 1970s; however, in the past two decades, PepMV has been recovered from all five continents. Tomato yield losses can reach up to 38%. The US3 strain, isolated in 2005 from tomato fruit sold in Maryland and fully sequenced here, has highest identity to European isolates, suggesting that the isolates may have a common origin and may have spread within the industry. The distribution and impact of the US3 isolate in the US tomato industry is unknown. This report will be of interest to an international audience of researchers in industry, academia, and government organizations with an interest in plant pathology and control of vegetable diseases.

Technical Abstract: Pepino mosaic virus (PepMV) is a widely distributed tomato virus. The complete genome sequence of a PepMV isolate ‘US3’ from infected tomato fruit was determined. The genome is 6,410 nucleotides and has a poly(A) tail. US3 shares highest homology with European EU-like isolates.
