A plant immune receptor mediates tritrophic interactions by linking caterpillar detection to predator recruitment https://www.biorxiv.org/content/10.1101/2025.07.29.667524v1
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

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 🥳

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.

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.

The glutamate receptor‐like GLR2.7 modulates insect egg‐induced defense responses in Arabidopsis
Upon perception of insect eggs, Arabidopsis thaliana activates a generic immune response that culminates in cell death (hypersensitive-like response (HR-like)). While this response can subsequently .....

The paralog SYR2 is an induced negative regulator w/ lower binding affinity.

Two surprising cases showing different ways to regulate immune receptors in plants -- the cell surface LRR-RK, SYR1 and the intracellular NLR DM2

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.

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!
