ABSTRACT: A Chlamydomonas reinhardtii (C. reinhardtii) chloroplast expression vector, papc-B, containing the apc-B gene that encodes the beta subunit of the light-harvesting antenna protein allophycocyanin (APC) of cyanobacteria, was constructed and transferred to the chloroplast genome of C. reinhardtii by the biolistic method. The transformants were identified by Southern blot, Western blot and ELISA assays after selection on resistant medium. The recombinant APC beta subunit was expressed in the C. reinhardtii chloroplast and accounted for up to 2–3% (w/w) of the total soluble protein (TSP), suggesting a promising prospect of using C. reinhardtii chloroplasts to produce functional plant-derived proteins.
