Comparative biology of IncQ and IncQ-like plasmids.

ABSTRACT: Plasmids belonging to Escherichia coli incompatibility group Q are relatively small (approximately 5 to 15 kb) and able to replicate in a remarkably broad range of bacterial hosts. These include gram-positive bacteria such as Brevibacterium and Mycobacterium and gram-negative bacteria such as Agrobacterium, Desulfovibrio, and cyanobacteria. These plasmids are mobilized by several self-transmissible plasmids into an even more diverse range of organisms including yeasts, plants, and animal cells. IncQ plasmids are thus highly promiscuous. Recently, several IncQ-like plasmids have been isolated from bacteria found in environments as diverse as piggery manure and highly acidic commercial mineral biooxidation plants. These IncQ-like plasmids belong to different incompatibility groups but have s
