A Marchantia gemmaling producing ectopic vegetative propagules

Happy to share the pre-print on GEMMIFER, a novel ERF required for the initiation of gemma in Marchantia. One of the coolest phenotypes that I have ever seen. Congratulations to Yuki and Go, who led this research. #PlantScience @biorxiv-plants.bsky.social www.biorxiv.org/content/10.6...

Targeting of the barley cell-surface receptor SRF3 by the Blumeria hordei effector AVRA13 overlaps with AVRA13 recognition by MLA and the induction of NLR-mediated cell death. Pathogens secrete effector proteins to promote virulence. Despite their recognition by barley Mla resistance genes, the structurally-related Blumeria hordei ( Bh ) AVRA effectors are maintained in the...

Wei Shi @wshisky.bsky.social & Merle‘s work is online. Wei really pushed this work from scratch and Merle linked it to MLA diversification…3rd (co-)first author paper in her PhD. Very proud PI!
And only possible through collaboration with G. Döhlemann, @grandpahiro.bsky.social &, Matt Platre. (1/x)

Cell-type specification at criticality underlies rhizoid patterning in the liverwort Marchantia polymorpha Rhizoid specification in Marchantia polymorpha gemmae involves lateral inhibition mediated by the microRNA FRH1, which represses the rhizoid-specific …

Happy to see this out! We describe a patterning mechanism underlying rhizoid specification in Marchantia. Contrary to classic patterning mechanisms (e.g., Turing), rhizoid specification depends on both randomness and lateral inhibition, involves subcritical bifurcations, and occurs at criticality!

Our latest work is out! We set out to see if we could recreate soil-nurturing plant growth in vitro. The plants looked happy and we see microbiome-induced cell-type-specific responses! A modest step but a fun challenge 😁

Thank you all for coming! It was great to have you in Osnabrück this year. Have a safe trip home and we hope to see you all next year in Göttingen. Stay tuned 🌱 #MAdLand2025 #Plantsci

Next, Hannah Lepper from @franzificht.bsky.social lab in Düsseldorf is investigating the enigmatic role of trehalose 6-phosphate during land plant evolution #MAdLand2025

A warm welcome to MAdLand2025, this year taking place in the beautiful botanical garden in Osnabrück 🌱. We are starting with a welcome talk by Sabine Zachgo, introducing us to Osnabrück and the bontanical garden 🌿 Looking forward to exciting talks about #plantsci #MAdLand2025

Franziska Fichtner (Heinrich Heine University Düsseldorf, Germany) presenting her talk, “Trehalose 6-phosphate coordinates sugar status with hormone signalling and plant development,” with slides projected behind her at the JXB 75th Anniversary Conference. She shared that some of this work was just accepted at JXB, so watch this space!

🚨 More on FFAT motifs in effector biology 🚨
Pseudomonas effector HopN1 interacts with ER tethering proteins (VAPs) via a FFAT motif. Furthermore, HopN1 interacts with a plant RHO-GTPase, mirroring YopT from the mammal pathogen Yersinia.

Happy to meet you at poster no. P-405 and to talk about my project at #2025ISMPMI this afternoon! 🌿

Here, we dissect the processing and release mechanism of the maize phytocytokine Zip1. Our results reveal a two-step mechanism of phytocytokine processing, translocation, activation and clearance.

It is sad that even basic research needs to be defended with utility. For me, basic research is in the same category as art: civilized societies can't do without it, because we all want to know who we are and what our place in the natural world is -- questions that only science can answer.

Wow

Check out our new study! We show that Arabidopsis uses the EDS1-SAG101-NRG1 node to trigger rapid yet contained cell death. Key finding: NRG1C variant regulates this process by competing with functional NRG1s. Amazing collaboration between Jijie Chai and Parker Labs.
