A fantastic resource for fern biology @natplants.nature.com 🔽! www.nature.com/articles/s41... Taking about ferns, are you interested by their immune system? Have a look at our recent preprint by @baptistebio.bsky.social @jacquet-chris.bsky.social 🔽 www.biorxiv.org/content/10.1...

The final version of our study on SERK-BIR module in Marchantia is out. Congratulations Cate and many thanks to collaborators! www.sciencedirect.com/science/arti...

[🚨Pre-print alert🚨] Excited to share our findings on the enigmatic ericoid mycorrhizal symbiosis. 🔴For the first time we provide evidence that ericoid mycorrhizae evolved from ancestral arbuscular mycorrhizae through the co-option nutrient-dependent regulation 👇! www.biorxiv.org/content/10.1...

Latest paper from @philcarella.bsky.social lab! Pseudomonas viridiflava as a naturally occurring pathogens of Marchantia. ▶️ T3SS matters ▶️ conserved effectors for infection in angio and Marchantia www.cell.com/current-biol...

Published fern transcriptomics (doi.org/10.1101/2024.08.27.609851 from @mutwil.bsky.social) suggest that SAR is controlled by pipecolic acid, rather than SA in ferns. They also use AMP to defend themelf [8/9]

Using AlphaFold, we found that their N-terminal domain is disordered 🌀 we referred them as disorder N-terminal NLRs (disN-NLRs) 🧬 They are ancestral in land plants and lost in angiosperms. [7/9]

NLRs (typical intracellular immune receptors) show more peculiar evolution in ferns: ✅ Ancestral type ‘Cbl-N’ of CC-NLR, lost in angiosperms ✅ TIR-NLR, RPW8-NLR ❌ Kin-NLR, Hyd NLR ✅ Overlooked TPR and CC-NB-ARC atypical NLRs ✅ NLR never described (in grey here). What could they be 🧐? [6/9]

We used NLtracker (from @jiorgoskourelis.bsky.social) and RGAugury to list putative fern immune receptors. First, 🧬 the diversity of cell-surface receptors resembles that of other land plants [5/9]

Fusarium and Colletotrichum infest ferns with similar strategies than what is known in angiosperms [4b/9]

Ferns have two phases: 🍀 gametophyte (tiny, algae-looking prothalli) 🌿 sporophyte (the familiar leafy fronds). Surprisingly the gametophyte of Pteris vittata is more resistant to Fusarium and Xylaria than the sporophyte! 🧐 [4/9]

We gathered a collection of 🍄 microbes and a collection of 🌿 ferns, and test their interactions 👀 Some pathosystems suggest non-host resistance mechanisms 🛡️ Some pathosystems suggest specific resistance mechanisms [3/9]

Most of what we know about plant immunity comes from angiosperms (~90% of land plants & most crops). 🌿 But what about other lineages? 🤔 Can we uncover novel immune strategies in ferns? Let’s take a closer look! [2/9]

🔗 Preprint alert: www.biorxiv.org/content/10.1... 🧵 New insights into plant immunity: using ferns to understand evolution! 🌱✨🌿 Excited to share my first (but not last) published research at @lrsv-toulouse.bsky.social. A THREAD … [1/9]
