Experimental design. The experiment was set up following a Complete Randomised Design (CRD). The treatments comprised of transgenic banana plantlets containing gusA and hpt genes and non transgenic control banana plants. These plantlets were innoculated with F. oxysporum (V5W2-9 NH3). The experiment was run for a period of 13-16 weeks during which normal agronomic practices were done to ensure proper growth. Each replicate had 5 transgenic plants and 2 controls. The experiment was repeated three times. Re-isolation of the fungal organisms was done by destructive sampling of the roots. The re-isolations were done three times.
