Symptoms induced by two CMV strains at 14 and 28 days post-inoculation (dpi). (A) The M strain of CMV (CMV-M) and recombinant virus, CMV-QMCP, induced chlorosis symptoms on Nicotiana tabacum cv. Samsun plants. The Q strain of CMV (CMV-Q) did not induce symptoms on tobacco plants, while an infection by the recombinant virus, CMV-MQCP, resulted in a lack of symptoms at 14 dpi and mild green mosaic symptoms at 28 dpi. (B) The accumulation of CP in the top systemic leaves were detected by western blot analysis with an anti-CP monoclonal antibody. Plant actin was used as the control.
