Primary metabolism underpins the execution of immune responses in different tissues of the same plant https://www.biorxiv.org/content/10.1101/2025.10.11.681807v1

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!

Exploring fern pathosystems and immune receptors to bridge gaps in plant immunity - BMC Biology
Land plants include angiosperms, gymnosperms, bryophytes, lycophytes, and ferns, each of which may deploy distinct strategies to resist pathogens. Here, we investigate fern-pathogen interactions by characterizing novel pathosystems and analyzing the diversity of fern immune receptors. A collection of fern species was inoculated with a diverse set of filamentous microbes, and disease symptoms were assessed. We further leveraged published genome mining tools to analyse the diversity of receptor-like kinases, receptor-like proteins (RLKs/RLPs) and nucleotide-binding and leucine-rich repeats (NLRs), along with key immune signalling components, in ferns. Our results reveal that ferns exhibit a range of responses to pathogens, including putative non-host resistance and more specific resistance mechanisms. Among ten ferns tested, Pteris vittata displays the broadest spectrum of pathogen compatibility. Genome mining indicates that ferns encode a diverse repertoire of putative immune receptors, antimicrobial peptides, and mediators of systemic acquired resistance. Ferns possess numerous RLKs/RLPs, resembling those required for cell-surface immunity in angiosperms. They also encode diverse NLRs, including sub-families lost in flowering plants. These findings provide insights into disease resistance evolution and open promising perspectives for crop protection strategies.

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 😁

Very happy and proud to share the #Spirogyra genome: 50 Mbp small, lacking almost all plastid division proteins and many transcription factors. Kudos to all the many people involved in this multi year project!

It was wonderful to have Bijun with us @mpi-mp-potsdam.bsky.social & @incavirus.bsky.social to finally "use our microscope to its full potential" as our core-facility put it! 🔬

Congrats to all, esp. @bijuntang.bsky.social and @xanderjones.bsky.social ! Super happy to be a part of this great story!

Fran @frangordilloc.bsky.social and I wrote this piece on one of our favorite topics: the evolutionary relevance of co-receptors for immune receptor transfer in #plants 🌱

Check also the beautiful paper by Zhang et al. on the PRR STOMR and discover what happened to its co-receptor 😱

Game changer for cell-based plant genetics: the labs of Caixia Gao & Jin-Long Qiu have developed very efficient self-replicating vectors and they just published a very nice proof-of-concept paper.
