Unfavourable environmental conditions represent considerable stress for plants. A high level of salt content (sodium chloride, NaCl) in the soil is just such a stressor which has a negative impact on plants. Salinization is a serious problem in agriculture especially in dry regions of the world.We have now discovered, for the first time, that salt stress triggers calcium signals in a special group of cells in plant roots, and that these signals form a “sodium-sensing niche”. We also identified a calcium-binding protein (CBL8) which contributes to salt tolerance specifically under severe salt stress conditions.

    Organismal homeostasis of the essential ion K+ requires sensing of its availability, efficient uptake, and defined distribution. Understanding plant K+ nutrition is essential to advance sustainable agriculture, but the mechanisms underlying K+ sensing and the orchestration of downstream responses have remained largely elusive. Here, we report where plants sense K+ deprivation and how this translates into spatially defined ROS signals to govern specific downstream responses.

    New insights in plant ABA signaling pathways: In this work we reconstructed single ABA signaling pathways in yeast for combinatorial analysis of ABA receptors and coreceptors, downstream-acting SnRK2 protein kinases and regulated transcription factors. The study establishes the suitability of the yeast system for the dissection of core signaling cascades and opens up future avenues of research on ligand-receptor regulation.

    New Biosensor provides insight into plant stress behaviour

    Until now, it was difficult to directly measure the occurrence of the signaling molecule phosphatidic acid (PA) in a certain tissues or organisms. Therefore, it remained unclear in which cells or in which parts of cells the substance was active and why its concentration is changing. The newly developed Sensor "PAleon" is able to change its fluorescent properties upon binding of bioactive PA and allows determination of cellular changes in phosphatidic acid concentration and distribution.

    How plants perceive salt

    High salt levels in the soil harm plant growth and limit crop yields. A salt-binding membrane lipid has been identified as being essential for salt perception and for triggering calcium signals that lead to salt tolerance.

    European plant scientists claim new rules for plant breeding

    One year ago, the Court of Justice of the European Union issued a ruling on genetic methods in plant breeding: on 25 July 2018, the judges ruled that plants bred using modern molecular biological methods (CRISPR-Cas genome editing) fall into the category of genetically modified organisms. According to current EU legislation, these plants are to be strictly regulated - in contrast to plants that have been genetically modified using conventional methods, called mutagenesis.

    How plants cope with iron deficiency

    New insights in plant iron acquisition

    Research groups from Heinrich Heine University Düsseldorf (HHU) and the University of Münster have discovered a new switch that plants use to control their responses to iron deficiency. The findings from their research on the model plant Arabidopsis thaliana is published in the journal "Developmental Cell".

    Plant scientists discover new molecular signaling pathway

    Jasmonic acid ensures that leave pores close if leaves are injured

    Plant biologists, including Prof. Jörg Kudla from the WWU Münster have shown: A mechanical injury of plant leaves causes rapid stomatal closure. This closure process is initiated by the plant hormone jasmonic acid.

    Pioneering biologists create a new crop through genome editing

    From wild plant to crops: CRISPR-Cas9 revolutionizes breeding / New tomato contains more valuable antioxidants

    For the first time, researchers have created, within a single generation, a new crop from a wild plant – the progenitor of our modern tomato – by using a modern process of genome editing. Participating in the study was a team led by Prof. Jörg Kudla from the Institute of Plant Biology and Biotechnology at the University of Münster.
