The activity of the TPC1 ion channel in the vacuole membrane (yellow) is essential for the excitability of the vacuole. On the left is a plant cell, in the middle the vacuole with chloroplasts (red) and a 3D reconstruction of the TPC1 crystal structure.

Researchers have filled two knowledge gaps: The vacuoles of plant cells can be excited and the TPC1 ion channel is involved in this process. The function of this channel, which is also found in humans, has been a mystery so far.

Dr. Ana Rita Brochado investigates the effect of antibiotics on bacteria.

Bacteria can quickly become resistant to antibiotics. Which mechanisms are responsible for this and how to counteract it? Dr. Ana Rita Brochado, who is setting up a new Emmy Noether Junior Research Group at the University of Würzburg, is investigating this.

When catching and digesting its prey, the Venus flytrap repeatedly counts the number of electrical signals (AP, action potentials). These processes are being investigated at the University of Würzburg.

How does the Venus flytrap count and calculate? This is what the Würzburg plant researcher Rainer Hedrich wants to find out. For his project, he will receive 1.5 million euros from a renowned funding programme.

The Würzburg biologists Markus Riederer (left) and Amauri Bueno found out why the leaves of the date palm do not dry out even at temperatures above 50 degrees Celsius.

The leaves of date palms can heat up to temperatures around 50 degrees Celsius. They survive thanks to a unique wax mixture that is essential for the existence in the desert.

Controlling cells with light: Professor Georg Nagel has won another award for his contributions to the invention and refinement of optogenetics. He received the prize along with other laureates in the USA.

Small-scale agricultural landscapes (left) offer advantages: they promote biological diversity, pollination and natural pest control.

Diversity beats monotony: a colourful patchwork of small, differently used plots can bring advantages to agriculture and nature. This is the result of a new study by the University of Würzburg.

Cells of a neuroblastoma: The red dots mark sites where the BRCA1 protein occurs in close contact with the RNA polymerase II. This is only the case if the protein MYCN is also present (right).

Two proteins work hand in hand to ensure that the tumour cells of neuroblastoma can grow at full speed. In "Nature", a Würzburg research team shows how the proteins can do this.

Icefish under water

Icefish live in an environment that should be deadly for them. Scientists have now investigated how they still manage to exist there and what evolutionary adaptations they have had to undergo in order to do so.

Two open stomatal pores on the surface of a fern leaf, each surrounded by two kidney-shaped guard cells. Right panel: important moments during the evolution of stomata. Stomata probably evolved in an early land plant, from which all today’s species descend, but were likely lost in liverworts. Some genes that control stomatal movement in flowering plants likely arose recently, in seed plants, from within ancient gene families that were present in algae. Signalling genes with specific roles in guard cells likely arose after mosses diverged from a common ancestor.

Plants that can manage with less water could make agriculture more sustainable. This is why a research team at the University of Würzburg is investigating how plants control their water balance.

Dr. Alexandro B. Leverkus, Universidad de Alcala (Madrid), is an Alexander von Humboldt Research Fellow at the Ecological Station Fabrikschleichach of the Biocenter (Zoology III) from 01.01.2019 to 31.12.2020. Leverkus is currently researching the topic "Forest disturbances in the Anthropocene: Unravelling ecological interactions between wildfire and (salvage) logging".

Scientists at the Universities of Würzburg and Bielefeld in Germany have discovered an unusual new light sensor in green algae. The sensor triggers a reaction that is similar to one in the human eye.

Fruit Fly

Insects and mammals have special sensors for different light intensities. These sensors selectively influence the circadian clocks and thereby control daily activity patterns.

Microscopy of centrioles.

Does expansion microscopy deliver true-to-life images of cellular structures? That was not sure yet. A new publication in "Nature Methods" shows for the first time that the method actually works reliably.

3d-Model of the guard cell potassium ion channel GORK

The plant hormone jasmonic acid also performs a function that was previously unknown. It ensures that the leaf pores close when leaves are injured. For the plant, this could be an emergency signal.
