Plant Biology

Plant Biology refers to the biological science of multicellular eukaryotes, also known as Plant Science.

  • Blattläuse als Bio-Sensoren

    Haben Pflanzen eine Art Nervensystem? Das ist nicht leicht herauszufinden, weil es keine guten Messmethoden gibt. Würzburger Pflanzenforscher nahmen dafür Blattläuse – und entdeckten, dass Pflanzen auf verschiedene Schädigungen jeweils anders reagieren.

  • Helpers for energy acquisition from plants

    Research into plant cells is far from complete. Scientists under the biochemist Professor Peter Dörmann at Universität Bonn have now succeeded in describing the function of chloroplasts in more detail. These are plant and algal cell structures that are responsible for photosynthesis. The results have now been published in the scientific journal "Proceedings of the National Academy of Sciences of the USA" (PNAS).

  • Monsanto takeover a “major challenge” for Bayer

    Lars Schweizer, Professor for Strategic Management at Goethe University Frankfurt, calls the planned takeover of Monsanto by German pharmaceuticals giant Bayer a major challenge.

  • Nature communications: From the plant to the microreactor

    Scientists at the Leibniz-Institute of Plant Biochemistry (IPB) in Halle/Saale (Germany) have fully elucidated the biosynthesis of carnosic acid. This discovery allowed the plant researchers around Prof. Alain Tissier to produce the economically valuable plant material by biotechnological means in yeast cells. The project was published in the renowned journal Nature Communications.

  • Photovoltaik nach dem Vorbild der Rose

    Mit einer Oberfläche wie bei Pflanzen können Solarzellen mehr Licht aufnehmen und damit mehr Strom erzeugen. Forscher des Karlsruher Instituts für Technologie (KIT) reproduzierten die epidermalen Zellen von Rosenblütenblättern, die eine besonders starke Antireflexwirkung besitzen, und integrierten die transparente Nachbildung in eine organische Solarzelle. Dies führte zu einer relativen Erhöhung der Effizienz von zwölf Prozent. Darüber berichten die Wissenschaftler in der Zeitschrift Advanced Optical Materials (DOI: 10.1002/adom.201600046).

  • Reduced ecosystem functions in oil palm plantations

    An interdisciplinary team of scientists from the University of Göttingen, the Helmholtz Centre for Environmental Research (UFZ) in Leipzig and Bogor Agricultural University in Indonesia has now performed a complete and multidisciplinary assessment of all ecosystem functions in oil palm plantations as compared to lowland forests. They found that in oil palm plantations, eleven out of 14 ecosystem functions showed a net decrease, some with an irreversible global impact.

  • Researchers image roots in the ground

    It's a familiar hazard of vacation time: While you're conspicuously absent, your colleagues in the office forget to water and fertilize the plants – often leaving behind nothing but a brownish skeleton. Whether a plant thrives or wastes away depends above all on whether its roots get enough water and nutrients. Geophysicists at the University of Bonn have now visualized such processes for the first time using electrical impedance tomography. The researchers have now published their results in the scientific journal "Biogeosciences".

    New study reveals previously underestimated carbon source

  • Wurzelsymbiose - Enge Freundschaft mit Kontrolle

    Die Symbiose mit Mykorrhiza-Pilzen verschafft Pflanzen einen besseren Zugang zu knappen Ressourcen. LMU-Forscher haben nun einen Mechanismus entdeckt, mit dem die Pflanze möglicherweise steuern kann, wie eng die Symbiose ist.
