Figure 2. RT-qPCR quantification of plum pox virus (PPV) in
virus-infected apricots grafted onto transgenic plum rootstocks. Each
value is the mean from three biological replicates, each a pool from
three plants. For each biological replicate six repetitions were run.
Asterisks indicate significant differences (P<0.05) with the
reference sample (apricots grafted onto the susceptible St5’-7
rootstock) according to a one-tail Dunnett’s test.
