Abstract: The sequence of the T.sub.L -DNA of Ri plasmids found in Agrobacterium rhizogenes strains HRI and A4 is disclosed. Sixteen open reading frames bounded by eukaryotic promoters, ribosome binding sites, and polyadenylation sites were found, five of which were observed to be transcripted in a developmentally and phenotypically regulated manner. The use of promoters and polyadenylation sites from pRi T.sub.L -DNA to control expression of heterologous foreign structural genes is taught, using as examples the structural genes for Phaseolus vulgaris storage protein (phaseolin), P. vulgaris lectin, a sweet protein (thaumatin), and Bacillus thuringiensis crystal protein. Vectors useful for manipulation of sequences of the structural genes and T-DNA are also provided.

Abstract: A foreign substance, such as DNA, is injected into plant cells or tissue by a biological ballistical insertion technique. High pressure propellant gas is employed to accelerate the macroprojectile containing microprojectiles coated with the foreign substance. A movable macroprojectile stop mechanism is provided between an upper injection chamber and a lower sample-holding chamber so that multiple shots of macroprojectiles can be made without disrupting the vacuum in the lower chamber. The stop mechanism includes removable stopper plugs for stopping the macroprojectile. A vacuum seal is provided between the stop mechanism and the lower chamber.
