To trap its prey, the Venus flytrap sends rapid electrical impulses, which are generated in response to touch or stress. But the molecular identity of the touch sensor has remained unclear. Japanese scientists have identified the molecular mechanism that triggers that response and have published their work in a new paper in the journal Nature Communications. As previously reported, the Venus flytrap attracts its prey with a pleasing fruity scent. When an insect lands on a leaf, it stimulates the highly sensitive trigger hairs that line the leaf. When the pressure becomes strong enough to bend those hairs, the plant will snap its leaves shut and trap the insect inside. Long cilia grab and hold the insect in place, much like fingers, as the plant begins to secrete digestive juices. The insect is digested slowly over five to 12 days, after which the trap reopens, releasing the dried-out husk of the insect into the wind. In 2016, Rainer Hedrich, a biophysicist at Julius-Maximilians-Universität Würzburg in Bavaria, Germany, led the team that discovered that the Venus flytrap could actually

Studie liefert vielversprechenden Fortschritt auf dem Weg zu nachhaltiger Landwirtschaft 🌱
Einem internationalem Forschungsteam um Prof. Dr. Thomas Ott, Professor an der Universität Freiburg und am Exzellenzclusters CIBSS – Centre for Integrative Biological Signalling Studies, hat erstmals gezeigt: Es ist das in Wurzeln von Hülsenfrüchten vorkommende Protein SYFO2, das die Grundlage dafür schafft, dass Hülsenfrüchte in der Lage sind, „sich selbst zu düngen“.
Den Forschenden ist es zudem gelungen, das Protein in Tomatenpflanzen zu aktivieren. 🍅
Diese Erkenntnisse eröffnen neue Perspektiven auf die Frage, wie der Einsatz von Düngemitteln bei Nutzpflanzen künftig reduziert werden könnte.🐝
Die Studie wurde im Fachmagazin Science veröffentlicht.
