Suppression of long-distance movement of tobacco etch virus in a nonsusceptible host.

Abstract excerpt

To investigate host functions involved in the tobacco etch potyvirus (TEV) infection process, a tobacco line (V20) with a strain-specific defect in supporting systemic infection was analyzed. Using a modified TEV encoding a reporter protein, beta-glucuronidase (GUS), genome amplification, cell-to-cell movement, and long-distance movement were measured in V20 and a susceptible line, Havana425. Comparable levels of...
