Interpretive Summary: Blueberry is a perennial crop and widely grown in the US. Blueberry production is affected by many diseases with majority being of viral origin. In this research we describe the identification of a new virus named blueberry virus L (BlVL). BlVL was determined to be widespread throughout US. Based on the genomic data obtained from seven virus isolates with six being from Oregon we devised a detection method which will be applied for virus detection. The detection assay will be used in future etiological studies to study the role of this new virus in disease complexes.

Technical Abstract: Screening of blueberry accessions using high throughput sequencing revealed the presence of a novel virus. Genomic structure and sequence are similar to that of nectarine stem pitting associated virus (NSPaV), a member of the genus Luteovirus, family Tombusviridae. Similar to NSPaV, the virus tentatively named Blueberry virus L (BlVL), does not contain readily identifiable movement proteins in any of the seven isolates sequenced. More than 600 samples collected from five states were screened and 79% were found infected, making BlVL the most widespread blueberry virus in the United States.
