Natural Chromosome-Chromid Fusion across rRNA Operons in a Burkholderiaceae Bacterium.

ABSTRACT: Chromids (secondary chromosomes) in bacterial genomes that are present in addition to the main chromosome appear to be evolutionarily conserved in some specific bacterial groups. In rare cases among these groups, a small number of strains from Rhizobiales and Vibrionales were shown to possess a naturally fused single chromosome that was reported to have been generated through intragenomic homologous recombination between repeated sequences on the chromosome and chromid. Similar examples have never been reported in the family Burkholderiaceae, a well-documented group that conserves chromids. Here, an in-depth genomic characterization was performed on a Burkholderiaceae bacterium that was isolated from a soil bacterial consortium maintained on diesel fuel and muta
