📣 New preprint! 🧵 Fantastic work led by @antonkraege.bsky.social Fact: Cerato-platanins are everywhere in fungi. Found across the fungal kingdom, implicated in everything from development to virulence to immune activation. But what do they *actually* do? We finally found the answer 👇

This story is now published in @natplants.nature.com ! 🎉🎩 Check out the final article here: nature.com/articles/s41477-026-02361-1 Very similar to the original bioRxiv preprint, with the addition of some cool polysome analysis (in the supplementals)! Thanks and congrats to everyone involved! 🙏

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.
