a
+, positive for HR reaction; −, negative for HR reaction.
b
Number of wilting plants/total number of inoculated plants.
c
Mean population of bacteria ± standard deviation (SD) recovered from BL-Cmm-inoculated stem tissue; no significant differences in population counts from inoculated plants were observed (P ≤ 0.05).
