Editor's Pick Research Article | Ecological and Evolutionary ScienceA Genus Definition for Bacteria and Archaea Based on a Standard Genome Relatedness IndexIn recent decades, the taxonomy of Bacteria and Archaea, and therefore genus designation, has been largely based on the use of a single ribosomal gene, the 16S rRNA gene, as a taxonomic marker. We propose an approach to delineate genera that excludes the direct use of the 16S rRNA gene and focuses on a standard genome relatedness index, the average nucleotide identity. Our findings are of importance to the microbiology...
Research Article | Molecular Biology and PhysiologyDNA-Membrane Anchor Facilitates Efficient Chromosome Translocation at a Distance in Bacillus subtilisTo properly segregate their chromosomes, organisms tightly regulate the organization and dynamics of their DNA. Aspects of the process by which DNA is translocated during sporulation are not yet fully understood, such as what factors indirectly influence the activity of the motor protein SpoIIIE. In this work, we have shown that a DNA-membrane tether mediated by RacA contributes to the activity of SpoIIIE. Loss of RacA nearly doubles...
