My first hairy root!
Thank you, Heike!
Now that Im finally here, I'm excited to announce that I've joined @salkinstitute.bsky.social as a postdoc with @lmueller.bsky.social Keep your eyes open for everything AMF symbiosis, peptide biogenesis, and the apoplast!
I am thrilled to share the peer reviewed version of our work on how the circadian clock gates In11-induced responses to tightly regulate induced antiherbivore responses in legumes. onlinelibrary.wiley.com/doi/10.1111/pc…
The work from my MSc with @silviarestrepo in collaboration with @dromius.bsky.social is finally out. We used an integrative approach to follow Phytophthora betacei along while infecting tree tomato. This was in my back burner during my Ph.D, and it materialized thanks to @epiplantpath.bsky.social 🥳
Microscopical and molecular characterization of the infection cycle of Phytophthora betacei during disease development on tree tomato (Solanum betaceum). https://www.biorxiv.org/content/10.1101/2025.09.11.675658v1
More fruits of studying natural variation in common bean (Phaseolus vulgaris): an interesting genetic basis for insensitivity to caterpillars' In11 elicitor 🐛

Thanks, Sagar! I'm looking forward to the fall!
I am incredibly proud of this work that was the result of collaborative science with chemical ecology experts Betty Benrey and Ted Turlings at @UniNeuchatel!
5. We conclude that INR is required for the emission of In11-induced volatile blends that attract natural predators to plants experiencing herbivory!
4. And the crown jewel: We took our NILs to a field in Mexico where we observed a 40% reduction in wasp attacks to caterpillars pinned to inr-1/inr-1 lines in an In11-specific manner.
3. We generated common bean near-isogenic lines with INR/INR or inr-1/inr-1 genotypes and demonstrated reduced direct antiherbivore defenses .
2. We leveraged natural variation in response to the HAMP inceptin (In11) in common bean to identify a non-responsive landrace with a L.O.F deletion in the INR gene that we termed inr-1.
I am thrilled to share the 2nd chapter of my PhD with @adsteinbrenner.bsky.social In collaboration with @tiszapatrick we demonstrated that the LRR-RLP INR is the missing molecular link between caterpillar recognition and predatory wasp recruitment in the field. A thread 1/6
How do plants detect insect eggs ? 🌱🦋
Our new paper on GLR2.7 and its role in plant defense responses to insect eggs is now out in @newphyt.bsky.social
Big thanks to the Reymond Lab @unil.bsky.social and our collaborators !

This will be my closing post for this #2025ISMPMI series. If you're a society member, you have access to ISMPMI rewind and can watch any talk the speaker agreed to have recorded. See you in Jeju, Korea in 2027!
First, work from Chang-Bao Li and Chuanyou Li (Shandong Ag U) on regulation of SYR1 receptor.
The paralog SYR2 is an induced negative regulator w/ lower binding affinity.
@nataliagupa.bsky.social highlighted that the module is only found in Solanoideae
www.sciencedirect.com/science/arti...
Also unpublished single nuclei and spacial transcriptomics data showing cool candidate genes important for the interaction!
We recently wrote two Preview articles of exciting MPMI papers in Mol Cell and Dev Cell.
Two surprising cases showing different ways to regulate immune receptors in plants -- the cell surface LRR-RK, SYR1 and the intracellular NLR DM2
Short summaries below 🧵🌱 #2025ISMPMI
Maria Harris closing #2025ISMPMI with the "most important plant-microbe interaction on earth".
CKL1 and CKL2 kinanses locate to the periarbuscular and plasma membranes during AMF symbiosis and their kinase activity is key for regulating downstream lipid biosynthesis.

Stunning talk by Dr. Stella Cesari (PHIM, Univ. Montpellier):
MAX effectors—structurally conserved but sequentially diverse.
Beyond HIPPs, AVR-Pib hits MAPKKKs—key players in plant immunity.
One fold, many targets?

Luis Rubio moves us from thinking about engineering against pathogens to engineering for nitrogen fixation.
They moved Nif genes into yeast mitochondria! But can this work in plants? Insolubiluty is the issue.
Screened variants by expressing in N benth - found one. Works in rice too!

Last day of #2025ISMPMI begins with Renier van der Hoorn and the amazing work on glycosirin, a bacterial inhibitor of BGAL1 that acts to manipulate plant glycobiology at the apoplast to evade recognition!
It was a pleasure to present our work on ‘the role of pest-associated microbes in insect-plant interactions’ at the #2025ISMPMI congress in Cologne. @mrogowska.bsky.social, @cuwelte.bsky.social, @robertsjansen.bsky.social, @guidopmi.bsky.social
