Putative deletion of flagellar genes in non-motile Acetobacter isolates from laboratory Drosophila. Genes from Acetobacter strains listed on the left are shown in relative size and orientation, and color-coded to indicate homology with A. okinawensis DsW_060. A. okinawensis DsW_060 (used as the reference strain) encodes all of its flagellar motility genes at a single locus, depicted as a thick black line. None of the genes within this locus have homologs in the genomes of non-motile strains shown below. However, genes adjacent to the flagellar locus of DsW_060 can be found in the non-motile strains, suggesting that a deletion gave rise to their current arrangement.
