Gentransfer auf der Pilzautobahn

UFZ-Forscher zeigen, wie Pilze die genetische Ausstattung von Bakterien zum Schadstoffabbau verbessern können

(PresseBox) (Leipzig, )
Bodenbakterien nutzen die weitverzweigten fädigen Strukturen von Pilzen, um sich auf ihnen fortzubewegen und zu neuen Nahrungsquellen zu gelangen. UFZ-Forscher konnten nun in ihrer aktuellen Studie im Fachmagazin Scientific Reports zeigen, dass diese sogenannten Pilz-Hyphen auch ein Hotspot für Gentransfer zwischen Bakterien sind. So sorgen Pilze für eine hohe bakterielle Vielfalt im Boden – was auch für den Abbau von Schadstoffen von Vorteil sein kann.

Für Bakterien ist der Lebensraum Boden ein ziemlich unwegsames Gelände: Trockene Bereiche und Luftporen stellen für sie unüberwindbare Hindernisse dar. Um sich fortzubewegen, benötigen sie einen Flüssigkeitsfilm in dem sie schwimmen können. Große Ansprüche stellen idy lcqtf wbbkm.
