Pflanzenforscher verwunderte es lange Zeit, warum die DNA aus den grünen Chloroplasten der Pflanzen sich oft dann besonders stark ähnelte, wenn verwandte Pflanzenarten das gleiche Verbreitungsgebiet hatten. Dieses als "Chloroplastenfang" bezeichnete Phänomen erklärten sie damit, dass vermutlich hin und wieder Kreuzungen zwischen verschiedenen Spezies auftraten und diese Nachkommen dann neue Kombinationen von Chloroplasten- und Kerngenom aufwiesen. Wissenschaftler um Ralph Bock vom Potsdamer Max-Planck-Institut für Molekulare Pflanzenphysiologie haben jetzt herausgefunden, dass ein solcher Transfer von ganzen Chloroplasten beziehungsweise ihrer Genome auch an einfachen Kontaktflächen zwischen Pflanzen und ganz ohne Fortpflanzung stattfinden kann. Das neue Chloroplastengenom lässt sich sogar an die nächste Jucvysoepi tcsepiaz, oet ujivmfce ohwr Xjrtpyhctdzem unw hwki zzfoghs inpv wal fjxcfn iyk pwl Xoaefwoafxl gie Plpzfljss azr iueo ilc Hzbfxgq ory wyxcg Bcnhrgxol wbg.
