Pineapple
Summary
The invention disclosed by DNA Plant Technology Corp. in a granted United States patent is directed to the transformation of embryogenic pineapple cells or pineapple callus with Agrobacterium having a T-DNA with a heterologous gene.
The recently granted Australian patent also uses an embryogenic cell or an embryogenic callus cell as a starting material for transformation.
In a recently filed PCT application, the Department of Primary Industries of Queensland (Australia) discloses methods for transforming pineapple cells and genetically modified pineapple by co-cultivating a pineapple explant with Agrobacterium having a gene of interest. Unlike the method used by DNA Plant Technology Corp., the transformed pineapple cells form an organogenic callus, which according to the applicants is easier and faster to obtain than an embryogenic callus.

Title – A method of plant transformation
Method for transforming pineapple cells by co-cultivating an explant with Agrobacterium having T-DNA with genetic material to be transformed into the plant cells. The selected transformed pineapple cells form an organogenic callus. A genetically modified pineapple plant is regenerated from the organogenic callus. * The present application also contains claims (1, 21, 41) directed to methods for transforming monocot plants in general, which are discussed under the section General transformation methods. |

Title – A method of plant transformation
Granted independent claims in this patent recite the same method of pineapple transformation as claims 60 and 77 in WO 2001/33943, except that the plant is limited to pineapple only and not those of “related plants”. |
