Eine Arbeitsgruppe aus Pflanzenphysiologen und Strukturbiologen der Universitäten Gießen und Marburg ist einen wichtigen Schritt weitergekommen bei der Erforschung der Funktionsweise von so genannten Phytochromen. Dies zeigt eine Publikation in der renommierten US-amerikanischen Fachzeitschrift "Proceedings of the National Academy of Sciences of the United States of America" (PNAS) unter dem Titel The structure of a complete phytochrome sensory module in the Pr ground state, die in diesen Tagen erscheint.
