Abstract
<h3>Summary</h3> Winegrape production in Ohio is challenging due to unpredictable winter temperatures, late and/or early frosts, a short growing season, and a plethora of diseases that can reduce grape yield and quality. Viral diseases in vineyards can result in significantly reduced economic returns due to reduced yield or diminished fruit quality. From 2012 to 2016, surveys of major viruses in commercial winegrapes were conducted to obtain a comprehensive understanding of the prevalence of viral diseases in Ohio vineyards. To date, these surveys have shown that <i>Grape leafroll associated viruses</i> 2 (GLRaV-2) and 3 (GLRaV-3) and <i>Grapevine red blotch virus</i> (GRBV) are present in commercial vines across the state.<sup>1,2</sup> In this study, we report that <i>Grapevine virus E</i> (GVE) is also present in Ohio grapevines, further increasing our knowledge of the types of grapevine viruses present in the state.

While the role of Grapevine virus E (GVE) in causing disease and displaying symptoms has yet to be deciphered, it has been reported to correlate with higher incidence and titer of other vitiviruses (i.e. Grapevine virus A and Grapevine virus B) and increased disease severity in vines coinfected with the economically important viruses Grape leafroll associated viruses 2 (GLRaV-2) and/or 3 GLRaV-3 [4, 14,15]
RNA sequencing (RNAseq) we discovered the near complete sequence of a new GVE isolate in the state of Ohio
Summary
The full statement of the Disclaimers is available at https://www.asevcatalyst.org/content/proprietaryrights-notice-catalyst. E (GVE) is present in Ohio grapevines, further increasing our knowledge of the types of grapevine viruses present in the state. Grapevines can be infected with a single virus or multiple viruses.
