DNA-Sequenzvergleiche einzelner Genorte deuteten auf sehr alte und hochvariable Polymorphismen

Symbiotic bacteria that live permanently with a host and are connected to its metabolism lose many genes over the course of evolution that are no longer required. A research team at the Max Planck Institute for Chemical Ecology investigated whether these highly specialized bacteria can adapt their gene activity to different environmental conditions despite their greatly reduced genome, using reed beetles of the genera Donacia and Macroplea. To this end, the expression of symbiont genes was analyzed at different temperatures and at various stages of the reed beetles‘ development. These symbionts retain only a few genes. Nevertheless, they were found to be able to adapt their gene expression in a targeted manner. For instance, they activate special stress genes in response to cold and adapt their metabolic pathways to their host’s diet during different life stages. This demonstrates that symbionts with a greatly reduced genome can still respond flexibly to the needs of their symbiotic partners.
The blue color shows the DNA of the beetle’s cells.
