Characterization of an Ilarvirus Associated with a Necrotic Shock Reaction in Blueberry

This is the authors' abstract. We don't add key points for this paper.

Blueberry bushes with scorch symptoms were found during a survey of blueberry fields in coastal British Columbia, Washington, and Oregon. Some were infected with blueberry scorch carlavirus; others in Washington and Oregon were found to contain a second virus, for which the name blueberry shock ilarvirus (BSIC) is proposed. BSIV was mechanically transmissible to several Nicotiana species but not to other herbaceous plants tested. BSIV was purified from N. clevelandii and had quasi-isometric particles approximately 27 nm in diameter, a single polypeptide with relative mass (M r ) of 27.300, and RNA moledules (M r 1.03, 0.84, 0.57, and 0.3 × 10 6 ) (...)
