We have studied the single rRNA gene cluster from the Archaeon, Pyrococcus furiosus. This isolate grows optimally at 100 degrees C and is thus a hyperthermophile. In P. furiosus, transcription of 16S rRNA is subject to regulation over a 7.5-fold range in response to a 20-fold increase in growth rate. The single cluster encoding the 16S and 23S rRNA genes of P. furiosus was cloned and the 1.9 kb region upstream of the 16S rRNA gene was sequenced.
我们研究了古菌嗜热栖热菌（Pyrococcus furiosus）的单个rRNA基因簇。该菌株在100摄氏度时生长最佳，因此是嗜热菌。在嗜热栖热菌中，16S rRNA的转录在生长速率增加20倍时会在7.5倍的范围内受到调控。克隆了编码嗜热栖热菌16S和23S rRNA基因的单个基因簇，并对16S rRNA基因上游1.9 kb的区域进行了测序。
