FIGURE 1.

An increase in HRF in systemic tissues of locally infected Arabidopsis plants depends on virus amount used for infection. Plants from line 15d8 were infected at 3 weeks of age, infected leaves were removed at 48 hpi, and HRF was analyzed one week later. “Ct” – non-infected plants. “Buffer” – buffer-treated plants. “50 ng”, “100 ng”, “200 ng” – plants infected with 50, 100, or 200 ng ORMV, respectively. The data are shown as the average number of recombination events per plant with SE calculated from three independent repetitions (20 plants in each experimental group). The letters indicate significantly different values (P < 0.05); similar letters indicate statistically similar values.
