It was a pleasure to recently give talks and meet with researchers working on exciting questions in plant sciences. My talks included “Addressing the Functional Annotation Bottleneck in Plant Genomics” and “Evolutionary Ups and Downs of Anthocyanin Biosynthesis”. #Genomics #Bioinformatics #Evolution

Very happy to share our new paper in Plant Physiology! 🌽 We uncover a 2-step mechanism controlling maize phytocytokine Zip1: ZmMC9 processes PROZIP1 intracellularly, enabling export of bioactive Ct-PROZIP1, while apoplastic proteases attenuate the signal. doi.org/10.1093/plph...

Highly recommended! PhD and postdoc opportunities in a great lab, with a super nice and creative PI, in a lovely city/region! If you want to be part of a young and dynamic group, run dont walk!

PLEASE SHARE! New job openings in my lab @zmbp-tuebingen.bsky.social. We have a broad interest into the mechanistic basis of how molecular complexes are rewired during cellular development in plants and during invasion by pathogens. 🌱🍄🔬 See details below 👇 #PlantSciJobs

We are delighted to announce the upcoming Gatersleben Research Conference “Genes, Chromosomes, and Genomes in Plants”, organized in partnership with the GPZ groups ‘Cytogenetics’ and ‘Genome Analysis’. When? November 3–5, 2027 Where? @leibnizipk.bsky.social, Germany Stay tuned for further updates!

It´s #MicroscopyFriday. Single cell transformation of barley stomata subsidiary cell. RACB-RIC171 complex (green), mCherry (red), cell wall autofluorescence (light blue). chlorophyll fluorescence (mighnight blue). Have a nice weekend.

Tomato MIK2A and Arabidopsis MIK2 appear to sense the same elicitor activity from Fusarium oxysporum. Both share some ectodomain surface amino acids for elicitor sensitivity. Tomato MIK2A, however, does not sense SCOOPs or SCOOP like peptides. Evolution of the MIK2 receptor clade is discussed.

Time for another preprint from the lab: www.biorxiv.org/content/10.6... Led by @yuanyuanzhang.bsky.social and @defengshen.bsky.social. We found some surprising secrets that connect and uncouple root barrier formation with systemic nitrogen signaling in shoots. see the thread below for more details

A tunable receptor separates root barrier formation from nutrient signaling through ligand-perception states

In roots, the endodermis controls nutrient entry by forming a barrier known as the Casparian strip. Yet how barrier-associated processes interface with systemic signaling remains unclear. Here, we sho...

So cool to see that the wild tomato species we're doing our research on are now also on display at the Kiel Botanical gardens! Thanks to all staff for making this possible and @sev1panier.bsky.social for organizing this!

It´s #Microscopyfriday again. Today, I found this on my harddrive. A GFP and barley Bax Inhibitor-1 expressing epidermal cell after single cell transformation of powdery mildew resistant mlo5 barley. Cell-autonomous heterologous compelementaion of susceptibilty allows for fungal sporulation.

I like the #Microscopyfriday idea and gonna post beautiful pictures from my lab. I start with Bipolaris sorokiniana attacking barley epidermis. Inverted picture. Note the nice halo around the appressorium like structure!

New lab, similar setup - still working… kind of 😅 First barley–mycorrhiza experiment for me in Freising. Colonization isn’t quite where I want it yet, but found some really nice arbuscules 🔬 Here, a barley root cell with F. mosseae arbuscule, stained with WGA-Fluorescein #Microscopyfriday

And that’s a wrap for the #TRR356 “Plant-Microbe” PhD & PostDoc retreat at beautiful Frauenchiemsee 🌿 We enjoyed talks from within the TRR and from our fantastic invited speakers, along with an engaging poster session, workshop, and career development discussions. A truly great event!

A true giant has left us. Widmar Tanner, a pioneer of plant transporter research, has passed away. He was a brilliant scientist, an outstanding mentor, and simply one of the kindest people one could meet. Rest in peace Widmar, and thank you for everything.
