GUS activities were determined after growth of X. campestris pv. campestris in NYG for 24 h and in MMX and XVM2 for 48 h. Data are the means ± standard deviations from triplicate measurements. Different letters indicate significant differences (P = 0.05). The experiment was repeated twice, and similar results were obtained.
