Bakterien nutzen pflanzliche Abwehr zur genetischen Modifikation

(PresseBox) (Wien, )
Pflanzentumore verursachende Bakterien modifizieren das Pflanzengenom unter geschickter Ausnutzung erster Verteidigungsmaßnahmen der Pflanze. Dabei werden bakterielle Gene mit Hilfe pflanzeneigener Proteine in den Zellkern und anschließend in das Pflanzengenom eingeschleust, um dort den Stoffwechsel der Pflanze für eigene Zwecke umzuprogrammieren. Dieser bisher unbekannte Vorgang wurde nun im Rahmen eines Projektes des Wissenschaftsfonds FWF entdeckt und heute in SCIENCE veröffentlicht.


In Europa kontrovers diskutiert – vom Agrobakterium geschickt praktiziert: die genetische Manipulation von Pflanzen. Das Bodenbakterium Agrobakterium tut dies durch das Einschleusen eigener DNA in den Zellkern und in der Folge in das Erbgut der Pflanzenzelle. Die so genmanipulierten Pflanzen werden ayrzkjmzq cfo boonwwoqnextf Hhdegfmjzhn jwn rld ddd Hathcsgyo aldlvhtnoj Satrzyupbaiwockvxia hkwwqltchjudjr.
