Almost all land plants employ an army of molecular editors who correct errors in their genetic information. Together with colleagues from Hanover, Ulm and Kyoto (Japan), researchers from the University of Bonn have now transferred one of these proofreaders from the moss Physcomitrium patens (previously known as Physcomitrella patens) into a flowering plant. Surprisingly, it performs its work there as reliably as in the moss itself.
