Transcription profiling of synchronized Sulfolobus acidocaldarius populations as they progress through the cell cycle


ABSTRACT: Exponentially growing Sulfolobus acidocaldarius were treated with NaAc to generate replication runout and arrest in G2 phase. The cells were then resuspended in fresh acetate-free media which generates a synchronous population. Samples for investigation of gene expression change were taken during the synchronised populations progress through the cell cycle.

In contrast to the cell division machineries of bacteria, euryarchaea, and eukaryotes, no division components have been identified in the second main archaeal phylum, Crenarchaeota. Here, we demonstrate that a three-gene operon, cdv, in the crenarchaeon Sulfolobus acidocaldarius, forms part of a unique cell division machinery. The operon is induced at the onset of genome segregation and division, and the Cdv proteins then polymerize between segregating nucleoids and persist throughout cell divis  ...[more]
