a
Plants were sampled at two locations above the inoculation point (IP) for X. fastidiosa culturing at 4 months after inoculation.
b
See Table 1 for additional information on isolates.
c
Number of infected plants/number of inoculated plants. In parenthesis is the mean number of CFU per gram of plant tissue (log10 value ± standard error).
