Good news today for us. Chao’s paper on microtubule processing during symbiotic responses in Medicago truncatula is now accepted in Plant Cell. Thanks to all co-authors for their valuable contributions.
This manuscript was initially placed at bioRxiv.
Nice collaborative work led by Rene Geurts’ lab (University of Wageningen) showing that NIN and NF-YA1 are also core regulators of nitrogen fixing symbiosis in Parasponia andersonii.

Just before Christmas a review written by Yvon Jaillais and Thomas has been published online in Plant Physiology. Here, we review current advances on membrane nanoscale organization from a proteolipid perspective and propose some new concepts.

Our TEM Unit with Marta as a co-author contributed to a beautiful piece of work of Sonja Albert’s lab of the University of Freiburg unravelling the molecular basis for swimming behaviour of Archaea. We greatly appreciate the confidence in our contributions and hope for further fruitful interactions.

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.

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.

New contribution from our TEM unit.
Our EM unit headed by Marta Rodriguez-Franco contributed to a new paper from Sonja Albers’ lab. In the current study, they show that cells of haloarchaea are polarized. The cellular positioning of proteins involved in chemotaxis and motility is spatially and temporally organized in these cells. This suggests the presence of a specific mechanism responsible for the positioning of macromolecular protein complexes in archaea.

A great story from the lab of Katharina Markmann (Tübingen, Germany) was just published in Science. Nikolaj Abel, PhD student in our team and co-author on the paper, contributed experiments as an MSc student to this work, where they demonstrate that miR2111 regulates the symbiotic repressor TOO MUCH LOVE. It functions as a hub during ‘autoregulation’, a pathway that balances the number and success of rhizobial infections in correspondence to the nitrogen status of the plant. Congratulations to Nikolaj and the rest of the team!
Our new PNAS paper is finally out. Demonstrating the mechanism of receptor nanoclustering during symbiotic infection and its importance for the infection process. Congratulations to first authors Pengbo Liang, our former PhD student Thomas Stratil and all co-authors for their great work.

Have a look at our newest review on “Commonalities and differences in controlling multipartite intracellular infections of legume roots by symbiotic microbes” which is now online at Plant & Cell Physiology. In this review we discuss different regulatory layers that control the co-existence of symbiotic microbes in the same root system.

Have a look at the new manuscript by the lab of Marco Trujillo (IPB Halle) on the regulation of exocyst Exo70B2 function, which has just been made available on the bioRxiv pre-print server. We were happy to contribute some imaging and image analysis to it. We wish good luck for submission process and hope for a constructive and fair reviewing process.
