Agrobacterium tumefaciens transformation of musa species

摘要

A method for transforming a Musa plant comprises:a. wounding meristematic tissue from a Musa plant by microparticle bombardment to generate a wounded Musa plant tissue and to facilitate access of Agrobacterium tumefaciens to Musa plant cells competent for transformation and regeneration;b. applying to said wounded Musa plant tissue at least one transformation competent Agrobacterium tumefaciens to transform said Musa plant, wherein said at least one transformation competent Agrobacterium tumefaciens harbours at least one Ti plasmid and at least one virulence gene, wherein said at least one Ti plasmid comprises at least one genetically engineered T-DNA to effect transformation of said Musa plant;c. growing said transformed Musa plant for a sufficient time to identify the presence of chimeric features;d. producing nonchimeric tissue by dividing said transformed Musa plant into segments which have at least one meristem which can regenerate into an intact plant and which have cells that are uniformly transformed to produce nonchimeric tissue; ande. growing said nonchimeric tissue into a nonchimeric plant.
