Materials and methods
The materials used in the study included; transgenic banana plantlets from local cultivars (Mbwazirume and Mpologoma) transformed with ß-glucuronidase (gusA) reporter gene under the control of CaMV35S promoter and a hygromycin resistance gene as the selectable marker and terminated by a nos sequence. The microorganisms tested were Fusarium oxysporum (V5W2-9 NH3).
