Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies equally to animal, plant and fungal cells. Through collaboration of several research institutes at a national and international level members of the “Plant Energy Biology” working group at Münster University, led by Prof. Markus Schwarzländer, and of the team led by Prof. Alex Costa at the University of Milan, have now identified the molecular machinery which enables calcium ions to be taken up into the mitochondria of plant cells – and that this form of transport plays an important role in their response to being touched. The study has now been published in the journal “The Plant Cell”.

Not only in the sea, but also in our soils there is "invisible" plastic - nanoplastics to be precise. This is a problem because it can be absorbed by plants and thus enter the food chain. But how much of such plastic is actually hiding in the soil? To find out, Dr. Melanie Braun from the University of Bonn wants to develop a new method. For her innovative project, the junior scientist has now received the Klaus Töpfer Research Prize worth 50,000 euros, which is awarded internally by the Transdisciplinary Research Area "Innovation and Technology for Sustainable Futures" (TRA Sustainable Futures) at the University of Bonn. The prize was named after Prof. Dr. Klaus Töpfer, former Federal Minister for the Environment and pioneer of climate policy, who was a guest at the award ceremony.

Protein molecules require a defined shape in order to function. When they are created, their building blocks are therefore linked together in a very specific way. Researchers at the University of Bonn are now taking a closer look at a key step in this process and are investigating the effects of transient oxygen starvation on protein folding in plants. Researchers from the University of Münster, the Technical University of Kaiserslautern and the University of Bielefeld were also involved in the study. The study has now been published in the journal Plant Cell.

Special distinction for Wulf Amelung: the professor of soil science and soil ecology at the Institute of Crop Sciences and Resource Conservation (INRES) at the University of Bonn and director of the Institute of Agrosphere at Forschungszentrum Jülich has now been admitted to the Leopoldina National Academy of Sciences. Amelung is assigned to the Section of Agricultural and Food Sciences.

"An apple a day keeps the doctor away" is an old English saying that means apples are healthy, so you should eat one every day. A very special specimen is the type "Adams Parmäne", which is currently on the red list of endangered native crops in Germany. The Wiesengut Teaching and Research Station at the University of Bonn is working with pomologist Barbara Bouillon from the "Biologische Station im Rhein-Sieg-Kreis" to preserve this special apple variety. She shows how this can work and why it is so important right now.

Coevolution between pathogens and host plant immune systems shapes a multifaceted network of interactions that remain phenotypically unrecognised and functionally elusive unless single players are depleted from the system. The maize-colonising fungus Ustilago maydis secretes a complex effector blend in order to suppress defence and redirect host metabolism in its favour. An international research team, including scientist from IPK Leibniz Institute and the University of Bonn, elucidates the effector protein Rip1, which is involved in immunity suppression during biotrophy. The results were published in the journal Plant Cell.

The use of genetically modified (GM) crops in agriculture remains contentious, especially in Europe. According to surveys, many people fear that these could have negative effects for human health and the environment. However, a new study shows that genetically modified crops could actually be good for the environment, and for the climate in particular. Results suggest that the adoption of GM crops in the European Union (EU) could reduce greenhouse gas emissions considerably. The study by scientists from the Breakthrough Institute in the USA and the University of Bonn in Germany was recently published in “Trends in Plant Science”.

According to a team of plant researchers, mitochondria provide unexpected help for cells in a crisis by respiring away harmful substances. The current study produced by the Institute of Biology and Biotechnology of Plants (IBBP) at the University of Münster and the Institute of Crop Science and Resource Conservation (INRES) at the University of Bonn has been published in the journal Plant Cell.
