Vectors and cells for preparing immunoprotective compositions derived from transgenic plants
View Patent ↗The inventions is drawn towards vectors and methods useful for preparing genetically transformed plant cells that express immunogens from pathogenic organisms which are used to produce immunoprotective particles useful in vaccine preparations. The invention includes plant optimized genes that encode the HN protein of Newcastle Disease Virus. The invention also relates to methods of producing an antigen in a transgenic plant.
1. An isolated plant-codon optimized nucleic acid molecule encoding the HN antigen of Newcastle Disease Virus comprising the sequence of SEQ ID NO:1.
2. A recombinant expression vector comprising SEQ ID NO:1.
3. The vector of claim 2 , wherein a plant-functional promoter is operably linked to SEQ ID NO:1.
4. A transgenic plant cell transformed with the vector of claim 2 .
5. The plant cell of claim 4 , wherein said plant cell is a potato plant cell, a tomato plant cell or a tobacco plant cell.
6. A transgenic plant transformed with the vector of claim 2 .
