Abstract
The invention is based on an expression enhancer sequence derived from the RNA-2 genome segment of a bipartite RNA virus, in which a target initiation site in the RNA-2 genome segment has been mutated. Deletion of appropriate start codons upstream of the main RNA2 translation initiation can greatly increase in foreign protein accumulation without the need for viral replication. Also provided are methods, vectors and systems, including the 'hyper-translatable' Cowpea Mosaic Virus ('CPMV-HT') based protein expression system.
