  • Patent number: 5428147
    Abstract: The sequence of the T-DNA of the octopine-type Ti plasmid found in Agrobacterium tumefaciens ATCC 15955 is disclosed. Fourteen open reading frames bounded by eukaryotic promoters, ribosome binding sites, and polyadenylation sites were found. The use of promoters and polyadenylation sites from pTi15955 to control expression of foreign structural genes is taught, using as examples the structural genes for the Phaseolus vulgaris storage protein phaseolin, P. vulgaris lectin, thaumatin, and Bacillus thuringiensis crystal protein. Vectors useful for manipulation of sequences of the structural genes and T-DNA are also provided.

  • Patent number: 5102796
    Abstract: The invention provides genetically modified plant cells having a plant structural gene introduced and expressed therein under the control of a T-DNA promoter. In particular, the invention provides genetically modified plant cells having the phaseolin gene introduced and expressed therein under the control of a T-DNA promoter. Also provided are novel strains of bacteria containing and replicating T-DNA which has been modified to contain an inserted plant structural gene under the control of a T-DNA promoter. Further, the invention provides plasmids having the ability to replicate in E. coli and comprising T-DNA which has been modified to contain an inserted plant structural gene under the control of a T-DNA promoter.
