Infection of viruses from the genera Bromovirus, Potyvirus, and Potexvirus in Nicotiana benthamiana induces significant up‐regulation of the genes that encode the HSP70 family, including binding immunoglobulin protein 2 (BiP2). Three up‐regulated genes were knocked down and infection assays with the...
