FIGURE 7.
Effects of the C85S mutation on viral infection and viral accumulation in TYLCV-inoculated N. benthamiana. (A) Symptoms in plants that were agroinoculated with wt TYLCV or TYLCV-C85S at 33 dpi. Mock represents mock-inoculated plants. (B) The time course of wt TYLCV or TYLCV-C85S infection. Values represent percentages of systemically infected plants as performed in Figure 6B. (C) The aboveground plant heights of mock-, TYLCV-, or TYLCV-C85S-inoculated N. benthamiana plants as measured at 33 dpi. (D) The accumulated viral DNA in plants was measured by qPCR. qPCR was done as Figure 6D. NbActin as an internal reference.
