Abstract

The nuclear gene PsaD encodes an abundant chloroplast protein located on the stromal side of the Photosystem I complex. We have cloned and sequenced a genomic fragment containing the PsaD gene from the green alga Chlamydomonas reinhardtii. Sequence comparison with its cDNA revealed that the PsaD ORF contains no introns. Thus, the regulatory sequences required for high-level expression of PsaD must lie in the flanking promoter and untranslated regions. We used this genomic fragment to construct a vector that allows for high-level expression of endogenous and exogenous genes, as well as cDNAs that could not be expressed from existing vectors. It is also possible to use the PsaD transit sequence to target the expressed protein to the chloroplast compartment.
