Agrobacterium-mediated transformation multiple shoot clumps multiple shoot clumps Agrobacterium-mediated transformation Musa. acuminata cv. Abstract An efficient protocol for the Agrobacterium tumefaciens-mediated transformation of banana (Musa acuminata. cv. ‘Pei Chiao’) is described. Cauliflower-like bud clumps (multiple bud clumps) were co-cultivated with A. tumefaciens EHA105 carrying a plasmid containing β-glucuronidase (GUS) reporter gene. In the absence of kanamycin, the bud clumps discs grew normally and produced shoots. In the presence of 30 mg/L kanamycin, the regeneration of the non-transform disc was inhibited. The growth and regeneration on both transformed and non-transformed discs were completely inhibited, and bleaching was observed under the concentration of 40 mg/L in the medium. In order to increase the regeneration of transformed plant, explants were cultured on growth medium without kanamycin after co-cultivation and putative plants were directly identified by Polymerase Chain Reaction (PCR) assay. Forty-eight out of 138 discs were found to have survived and produced shoots. Twenty-three plants of these were confirmed to contain the GUS transgene by PCR. The GUS expression in transgenic plants was only found in roots but not in leaves. Only four transgenic plants (PCR positive) found GUS expression at different RNA levels by RT-PCR (Reverse Transcriptase PCR) assay. The protocol is useful for the breeding of banana through genetic transformation. Advisor Committee Ho-Chin-Wen - advisor
