Complete genome sequence of Lysinibacillus varians GY32, a bacterium with filament-to-rod cell cycle

Abstract

The complete genome sequence of Lysinibacillus varians GY32 was determined to be 4 662 822 base pairs in a single circular chromosome. Genes in cell division, cell cycle, surface layer and cell wall synthesis are foundation of its unique cell morphology. The genome contains multiple clusters of transcriptional regulator, two-component system and sigma factors, providing the organism with the ability to regulate a filament-to-rod cell cycle progression. L. varians GY32 was, to our knowledge, the first bacterium with a filament-to-rod cell cycle to be sequenced and its annotated genome might provide new insights into our understanding of bacterial cell cycle regulation.
