Systemic Cell Death Is Elicited by the Interaction of a Single Gene in Nicotiana clevelandii and Gene VI of Cauliflower Mosaic Virus
Cauliflower mosaic virus (CaMV) strains D4 and W260 can be distinguished by the type of symptoms they induce in Nicotiana clevelandii and N.edwardsonii.W260 induces systemic cell death in addition to a mosaic symptom in N.clevelandii and a hypersensitive response (HR) in N.edwardsonii, whereas D4 induces a systemic mosaic in both hosts.To determine
