Phenotypes caused by transient expression of the MaYVV C4 protein. (A) Phenotypes of N. benthamiana plants infected with PVX alone or with PVX/C4. The plants infected with PVX/C4 showed leaf upward curling and abnormal flowering symptoms. Photographs were taken at 30 dpi. (B) RT-qPCR analyses of PVX accumulation in the systemic leaves of the PVX- or PVX/C4-infected N. benthamiana at 15 dpi. Expression of Nbactin was used as an internal control. indicates the two treatments differ significantly (P value < 0.05 by the Student’s t-test). The experiment was repeated three times with similar results.
