摘要:
A method of producing a virus like particle (VLP) in a plant is provided. The method comprises introducing a first nucleic acid into the plant, or portion of the plant. The first nucleic acid comprising a first regulatory region active in the plant operatively linked to a nucleotide sequence encoding a native rabies virus structural protein. The nucleotide sequence may further comprise one or more than one amplification element. Optionally, a second nucleic acid might be introduced into the plant, or portion of the plant. The second nucleic acid comprising a second regulatory region active in the plant and operatively linked to a nucleotide sequence encoding a matrix protein, for example but not limited to a rabies matrix protein. The plant or portion of the plant is incubated under conditions that permit the expression of the nucleic acids, thereby producing the VLP.
摘要:
A method of producing a virus like particle (VLP) in a plant, and compositions comprising VLPs, are provided. The method involves introducing a nucleic acid comprising a regulatory region active in the plant and operatively linked to a chimeric nucleotide sequence encoding, in series, an ectodomain from a virus trimeric surface protein or fragment thereof, fused to an influenza transmembrane domain and cytoplasmic tail, into the plant, or portion of the plant, the ectodomain is from a non-influenza virus trimeric surface protein and heterologous with respect to the influenza transmembrane domain, and the cytoplasmic tail. The plant or portion of the plant are incubated under conditions that permit the expression of the nucleic acid, thereby producing the VLP. A VLP produced by this method are also provided.
摘要:
A plant expression system and methods for expressing a protein of interest in a plant are provided. The plant expression system comprises a first nucleic acid sequence regulatory region sequence, operatively linked with a one or more than one comovirus enhancer, a nucleotide sequence of interest, one or more than one geminivirus amplification elements, and a second nucleic acid encoding a geminivirus replicase. The method of producing a protein of interest in a plant, involves introducing the plant expression system into a plant, or portion of the plant, and incubating the plant or the portion of the plant under conditions that permit the expression of the nucleotide sequence and producing the protein of interest.

摘要:
A method for synthesizing a protein of interest within a plant or a portion of a plant is provided. The method involves introducing one or more than one nucleic acid sequence encoding a protein of interest operatively linked with a regulatory region obtained from a photosynthetic gene that is active in the plant, in a transient manner. The plant is then maintained under conditions that permit the nucleic acid sequence encoding the protein of interest to be expressed in the plant or the portion of the plant. The plant may be pruned prior to the introducing one or more than one nucleic acid sequence.
摘要:
Methods of preparing plant-derived proteins or suprastructure proteins, are provided. The method may comprise obtaining a plant, or plant matter comprising apoplast-localized proteins, or suprastructure proteins, producing a protoplast/spheroplast fraction and apoplast fraction from the plant or plant matter, and recovering the apoplast fraction. The apoplast fraction comprises plant-derived proteins or suprastructure proteins. Alternatively, the proteins, or suprastructure proteins, may be obtained from plant or plant matter comprising plant-derived proteins or suprastructure proteins, by digesting the plant matter using a cell wall degrading enzyme composition to produced a digested fraction. The digested fraction is filtered to produced a filtered fraction, and the plant-derived proteins or suprastructure proteins, are recovered from the filtered fraction.
