Nesseltiere wie Seeanemonen gehören zu den ersten Lebewesen in der Geschichte der Evolution, die Muskeln entwickelt haben. Ulrich Technau, Entwicklungsbiologe der Universität Wien, und sein Team untersuchen, ob diese einfachen Organismen, deren Ursprung vor etwa 600 Millionen Jahren liegt, bereits die molekularen Anlagen für die Entstehung der viel komplexeren Muskulatur von Wirbeltieren in sich tragen. Dabei gelang es den ForscherInnen zum ersten Mal, transgene Seeanemonen zu züchten - Seeanemonen, deren Muskelzellen buchstäblich rot werden. Die Ergebnisse der Studie erscheinen demnächst in der renommierten Fachzeitschrift "Proceedings of the National Academy of Sciences (PNAS)".
