The invention disclosed by Fillatti & Comai (owned by Calgene Inc.) in patents granted in the United States and Australia is directed to the transformation of poplar leaves with an armed (tumor-causing genes) A. tumefaciens having a gene of interest.
The construct inserted into a transformed poplar comprises a transcription initiation region, an open reading frame (ORF) expressing a peptide and a transcription termination region.
