✦ Synopsis
A eDNA clone encoding the photosystem I subunit, PSI-G was isolated from barley using an oligonucleotide specifying a partial amino acid sequence from a 9 kDa polypeptide of barley photosystem I. The 724 bp sequence contains an open reading frame encoding a precursor polypeptide of 15 107 kDa. Import studies using the in vitro expressed barley PsaG eDNA clone demonstrate that PSI-G migrates with an apparent molecular mass of 9 kDa on SDS-polyacrylamide gels together with PSI-C (subunit-VII). The previous assignment of the gene product of

Several cDNA clones encoding subunit XI of photosystem I reaction center (PSI-L) have been isolated from two 2gtl 1 expression libraries based on polyadenylated RNA of spinach seedlings illuminated for 4 and 16 h, respectively. The precursor polypeptide made from these recombinant DNAs in vitro can
