We are seeking a highly motivated and skilled PhD student to join the team of Marco Trujillo working on a DFG-funded project in collaboration with our lab. The aim of the study will be elucidating regulatory mechanisms governing the secretory activity during plant immune responses.

New Preprint on proximity labelling in plants
We are happy to share results we obtained in a multi-effort approach together with the labs of Daniel Van Damme (VIB Ghent, Belgium), Panos Moschou (Uppsala BioCenter, Sweden) and Geert De Jaeger (VIB Ghent, Belgium). We demonstrate robust functionality of proximity-dependent biotin labelling in plants.
You can find the pdf version of the manuscript here.

New paper on regulation of nodulation
Work from a collaboration with Xia Li’s lab at Huazhong Agricultural University (China) has just been published online in Molecular Plant. Congratulations to Xia’s team and Chao Su from our lab!
Here, we report that the microRNA172c (miR172c) activates soybean (Glycine max) Rhizobia-Induced CLE1 (GmRIC1) and GmRIC2 by removing the transcriptional repression of these genes by soybean Nodule Number Control 1 (NNC1), thereby activating the AON pathway. NNC1 interacts with GmNINa, the soybean ortholog of Lotus NODULE INCEPTION (NIN) and hampers its transcriptional activation of GmRIC1 and GmRIC2. Importantly, GmNINa acts as a transcriptional activator of miR172c. Intriguingly, NNC1 can transcriptionally repress miR172c expression, introducing a novel negative feedback loop into the NNC1 regulatory network. Moreover, GmNINa interacts with NNC1 and can relieve the NNC1-mediated repression of miR172c transcription. Thus, the GmNINa/miR172c/NNC1 network is a master switch that coordinately regulates and optimizes NF and AON signaling, supporting the balance between nodulation and AON in soybean.

Seminar (June 7): Yoselin Benitez-Alfonso (Leeds, UK)
We are happy to host Yoselin Benetitez-Alfonso from the University of Leeds on 6.-7. June 2019 at our institute and learn more about her exciting working on callose and plasmodesmata and their role in transcellular signaling. She will give a seminar on 7. June at 10:15 am in room SR 0.043 on “The role of callose and cell walls on the regulation of symplastic intercellular signalling and symbiosis“.

Clusters of Exellence funded!
Great moment for the University of Freiburg. The cluster applications of CIBSS and livMatS receive full funding as “excellence clusters” after both had been pre-selected by the German Research Foundation (DFG) about a year ago. And this also means great news for our lab as we are part of the CIBSS cluster, where we will further investigate the functionality of membrane nanodomains during host cell infections.

Green City – Green Science Freiburg
Open house at the university’s outdoor research facilities.
Location: Outdoor research site/Freilandflächen am Flughafen.
Date: 24.06.2018 from 3-5 pm.
Research requires space. Especially researchers who examine natural processes from such fields as ecology, hydrology and forest science are dependent on outdoor facilities for their experiments. For this reason, examination areas were created on Freiburg airport’s campus in the spring 2013 upon which questions such as biodiversity’s role, the effects of climate change as well as sustainability of forest production systems are studied. A lot of experiments are done there. On the second day of the open house, researchers from the Faculties of Biology and Environment and Natural Resources at the University of Freiburg will provide a tour through the test facilities, introduce the measuring equipment used and will be available to answer questions about the experiments and their results. Homemade cakes and soft drinks will be offered.Further information can be found here and on Twitter @PresseUniFR
