Abstract

We have investigated the expression of the bacteriorhodopsin gene (bop) and the gas vesicle protein gene (gvpA) in the extremely halophilic archaebacterium Halobacterium halobium, using primer-directed reverse transcription of RNA to quantify message levels. The level of gvpA gene transcript was found to increase about 5-fold from early to mid-logarithmic growth phase, while the level of bop gene transcript increased about 20-fold from mid-logarithmic to stationary phase. Transcriptional induction of both the gvpA and bop genes was significantly reduced by aeration and almost completely blocked by the DNA gyrase inhibitor novobiocin.
