(i) providing to said plant, said plant tissue or said plant cells a plus-sense single-stranded RNA viral vector encoding at least said first and said second protein subunit or (ii) providing to said plant, said plant tissue or said plant cells a first and a second plus-sense single-stranded RNA viral vector, said first viral vector encoding at least said first protein subunit, said second viral vector encoding at least said second protein subunit, whereby at least said first viral vector and said second viral vector are non-competing viral vectors.
摘要:
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 heterologous 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) 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.

摘要:
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.
摘要:
A process of producing a protein or polypeptide of interest in a plant or in plant is provided, comprising: (i) transforming or transfecting a plant of plant cells with a nucleotide sequence having a coding region encoding a fusion protein comprising the protein or polypeptide of interest, a signal peptide functional for targeting said fusion protein to the apoplast, and a polypeptide capable of binding the fusion protein to a cell wall component, (ii) enriching cell wall components having expressed and bound fusion protein, and separating the protein or polypeptide of interest or a protein comprising the protein or polypeptide interest.
摘要:
This invention discloses a biologically safe process of causing amplification and/or expression of one or more nucleic acid sequences of interest in a plant, plant tissue, plant cell or cell culture, characterized in that a plant cell is provided with at least two precursor vectors designed for undergoing processing by site-specific recombination in said cell, whereby due to said processing said plant cell is endowed with at least one replicon which provide(s) for said amplification and/or expression.
摘要:
The invention describes a method of controlling a biochemical process or a biochemical cascade in plants utilizing a process of interaction between a heterologous DNA sequence in a transgenic plant, on one side, and a heterologous DNA sequence in a plant viral transfection vector, on the other. Optionally, the process of interaction further involves a low molecular weight component. The process of interaction makes the infection with a viral transfection vector a gene-'switch' which switches on a biochemical process or cascade of interest via various reactions such as nucleic acid recombination, replication, transcription, restriction, translation, protein folding, assembly, targeting, posttranslational processing, or enzymatic reaction. Further a process for producing a product in a transgenic plant and kit of parts for such a process is provided.
摘要:
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.
