Abstract
The clustered genes psbD and psbC covering together close to 22 000 nu cleotides contain ten and eleven exons, respectively. The correspondin g translation products, i.e, Photosystem II core 34 kDa (D2) protein a nd the CP43 chlorophyll binding protein are highly conserved. Introns vary in length from 305 to 4144 nucleotides. The two genes have about 900 nucleotides in common including an intron. To obtain stable mRNAs of about 1400 (psbD) and 1500 (psbC) nucleotides the pre-transcripts m ust undergo differential processing and/or splicing events within the overlapping region.
