The mechanisms of regulation of the genes encoding PS I and PS II components are largely unknown for the unicellular cyanobacterium Synechocystis sp. PCC 6803. In an attempt to elucidate how PS I and PS II biogenesis is controlled, we have isolated RNA from cells grown in various light conditions and analyzed relative steady-state levels of transcripts on Northern blots. Results from blots probed with psaA and psaB (which we recently cloned and sequenced) as well as previously isolated clones for psbA1, psbA2, psbD2, psaD, rbcL, and rrn will be presented. Preliminary data indicate the psbA and psaA-psaB transcripts accumulate in cells put in the dark, although the psaA-psaB transcript levels are somewhat reduced in the dark. Future experiments will focus on molecular analysis of the promoter region for the psaA-psaB operon.
