Evaluation of transgenic lines for enhanced resistance to Xanthomonas campestris pv. musacearum using potted plants.

^* Mean of three replicates.

^† The disease symptoms were chlorosis or necrosis on the leaves of inoculated plants.

^‡ Significant differences (P < 0.05) in symptoms in a comparison of transgenic lines with nontransgenic control plants.

Degree of wilting (grade): 0, no symptoms; 1, only the leaf inoculated wilted; 2, two to three leaves wilted; 3, four to five leaves wilted; 4, all leaves wilted but plant still alive; 5, whole plant died.

Resistance (%) = (Reduction in wilting/Total number of leaves wilted in control) × 100.
