Self-defense strategies of moss
Date:6/10/2010

Slugs are every gardener's enemy: They can destroy overnight, what he has sown and looked after lovingly. But snails don't like all plants in the same way they shun moss. Why is that so? This question was already posed by the botanist and founder of Chemical Ecology, Ernst Stahl, at the end of the 19th century in Jena. More than a hundred years later chemists from Friedrich-Schiller-University Jena (Germany) found a possible answer: "Moss is capable of building up chemical compounds that protect them from enemies," says Prof. Dr. Georg Pohnert of Jena University. Ernst Stahl had come to the same conclusion after tests. Now the holder of the Chair of Instrumental analytics and his team succeeded in identifying these compounds and in proving their pest repellent properties beyond doubt. The chemists working with Prof. Pohnert published their research results in the latest edition of the german trade journal Angewandte Chemie.

What spoils the snails appetite for moss are so called oxylipins. "These are compounds which are formed from unsaturated fatty acids by pathways involving oxidation when the moss is being damaged," Prof. Pohnert explains. The Jena chemists analysed the moss Dicranum scoparium, also known as ordinary Broom Fork-moss that can be found in nearly all European woods. During their research the scientists found many formerly unknown compounds, among them new, very unusual oxylipins.

"Motivated by the observation that in other organisms, oxylipins often work directly as defence metabolites or are part of the regulation of defence mechanisms, we have analysed the impact of these compounds more accurately," says Prof. Pohnert, who, along with his group, so far focused on the chemical defence strategies of marine organisms. To prove the retardant impact of oxylipins against snail damage, Jena scientists engaged two well known "experts" - the slugs Arion lusitanicus which were being offered two salad leaves.
