BAK1 and cytomegalovirus infection: Thus, although CMV infection can trigger a BAK1‐dependent response (induction of feeding deterrence against aphids), neither BAK1 nor BKK1 appear to condition basal resistance against CMV, which contrasts with the roles of these co‐receptors in maintaining basal resistance against several other viruses (Kørner et al., 2013; Nicaise & Candresse, 2017; Niehl et al., 2016; Yang et al., 2010; Zorzatto et al., 2015).
