Interested in fossils, evo-devo, and how mathematical modeling can help us understand the evolution of developmental processes? In our latest preprint, we uncover an ancestral lateral inhibition mechanism underlying epidermal patterning in liverworts.

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!

I’m very happy to see my fist article now officially published 🥳 great work by my partner in crime @wolki95.bsky.social and the rest of @teamthomma.bsky.social! Find it here: doi.org/10.1111/nph.... or have a look at the 🧵⬇️

📣 New @biorxiv-microbiol.bsky.social preprint, another joint-venture of @wolki95.bsky.social & @antonkraege.bsky.social, co-directed by @nicksnelders.bsky.social. Here’s a 🧵

New pre-print from the team!

The manuscript is @emma-raven.bsky.social's PhD work showing that whether a leaf is a carbon sink or a carbon source influences how they execute immune responses.

Have a read!

🚨 New paper alert!

Our work is published in PNAS! @junli-wang.bsky.social @mpipz.bsky.social

In this study, we uncover how NLR-assembled and canonical Ca2+ ion channels cooperate to confer robust resistance against disease in plants.

Check it out here: www.pnas.org/doi/10.1073/...

Plant-associated fungi co-opt ancient antimicrobials for host manipulation Evolutionary histories of effector proteins secreted by fungal pathogens to mediate plant colonization remain largely elusive. While most functionally characterized effectors modulate plant immunity, ...

📣 NEW PREPRINT 📝

We identified evolutionary origins of many fungal effectors!
We show that fungi secrete lots of antimicrobial proteins, and that some of them were repurposed by plant pathogens for host immune suppression.
