Abstract:
A process of producing a protein of interest by expression of said protein of interest from a sequence of interest in a plant or in plant leaves, comprising: a) transfecting said plant or said plant leaves by infiltrating said plant or said plant leaves with an Agrobacterium strain in the presence of a complementing factor, said Agrobacterium strain containing in T-DNA a heterelogous DNA sequence having a sequence portion encoding a replicon, wherein said sequence encoding a replicon contains sequences necessary for replicon function of said replicon, said sequences being derived from a plant virus, and said sequence of interest to be expressed from said replicon, b) optionally isolating said protein of interest from said plant or said plant leaves infiltrated in step (a), wherein said Agrobacterium strain is provided with a first genetic modification rendering said Agrobacterium strain defective for transfecting organisms with said T-DNA in the absence of said complementing factor.

Abstract:
A process for producing multicellular plants, plant organs or plant tissues transformed on their plastome by the following steps is provided: (a) altering or disrupting the function of a gene in a plastid genome for producing a selectable or recognizable phenotype; (b) separating or selecting plants or cells having plastids expressing said phenotype; (c) transforming said plastid genome of said separated or selected plant, plant organ or plant tissue with at least one transformation vector having a restoring sequence capable of restoring said function; and (d) separating or selecting said transformed plant, plant organ or plant tissue having plastids expressing said restored function.
Abstract:
A process of generating transgenic plants or plant cells transformed on their plastome, comprising (a) introducing into plant plastids a first DNA molecule and a second DNA molecule, wherein said first DNA molecule contains a first region homologous to a region of the plastome for directing plastome integration and a first sequence of interest, and said second DNA molecule contains a second region homologous to a region of the plastome for directing plastome integration and a second sequence of interest, whereby a sequence segment of said first sequence of interest is homologous to a sequence segment of said second sequence of interest, and selecting transformants having an integration sequence stably integrated in the plastome, whereby said integration sequence contains at least a portion of said first and at least a portion of said second sequence of interest as a continuous sequence.
Abstract:
This invention discloses a novel process and vector therefore for producing a multicellular plant or plant cells having stably transformed plastids. This process comprises transforming plastids or plant cells via homologous recombination with a DNA molecule enabling DNA modification, whereby said DNA molecule comprises a fragment of a gene requiring for expression a sequence element of the host plastid. The invention also includes the use of novel selection inhibitors for plastic transformation and the possibility of performing multiple rounds of transformation without accumulation of resistance genes.
