INTRACELLULAR DIRECTED DELIVERY OF EXPRESSION PRODUCTS

摘要

Novel chimeric constructions are provided for expression of chimeric genes having an N-terminus transit peptide for efficient translocation from the cytoplasm to the chloroplast and a foreign gene capable of functioning in association with the chloroplast. Particularly, the transit peptide from the small subunit of ribulose-1,5-bisphosphate carboxylase is joined to an aroA gene expressing an inhibitor resistant enzyme with retention of the processing signal to provide the mature aroA expression product in the chloroplast.
