Nach 160 Jahren überführt - Herbarien geben Genom des Verursachers der Irischen Hungersnot preis

(PresseBox) (Frankfurt am Main, )
Für Botaniker waren Herbarien, in denen Belege getrockneter Pflanzen über Jahrhunderte aufbewahrt werden, schon immer ein Schatz. Doch auch für Molekulargenetiker sind diese Sammlungen zunehmend wichtig. In einer jetzt im Journal eLife veröffentlichten Studie hat ein internationales Team unter Beteiligung mehrerer BiK-F-Wissenschaftler jetzt gezeigt, dass das Erbgut von Pflanzen ebenso wie das ihrer Krankheitserreger aus historischen Proben sehr akkurat ausgelesen werden kann. Die Molekularbiologen rekonstruierten die historische Verbreitung des Kartoffelfäule-Erregers und eröffnen so neue Möglichkeiten für die Geschichtsschreibung.

Phytophthora infestans schrieb Geschichte, als der Erreger Mitte des 19. Jahrhunderts große Teile der europäischen Kartoffelernte vernichtete. Am härtesten wurde dabei Irland bhvhogsgr.
