Silencing of MiPSKs compromises gall formation in tomato plants and parasitic success

All four MiPSK genes identified exhibited strong expression in root-attracted J2s compared with other developmental stages.

Meloidgyne incognita was selected for further experimental analysis. In situ hybridization assay shows that MiPSK transcripts are expressed in the esophageal glands of nematodes

PSK like proteins from PPN forms monophyletic clade

Interestingly, some PSK motifs in nematode encoded proteins are identical to plant PSK ones. However, the variable domains aa are quite different from the plant ones.

Happy to see this in biorxiv 🎉. Really proud of how it started and ended. Very first report of new peptide class “ PSK” encoded by parasitic nematodes. Nematodes getting smarter 🎉 Congrats to all authors

🍅 Happy #TomatoTuesday from @nature.com Nature Genetics! #PlantScience 🍅

it was great to collaborate with @lmueller.bsky.social to help characterize the Medicago crn mutant!

Thank you @aribidopsis.bsky.social for this invitation and was a good open discussion. I really enjoyed it and hope to join more in future.

SALICYLIC ACID SENSOR1 reveals the propagation of an SA hormone surge during plant pathogen advance Salicylic acid (SA) is a key phytohormone that orchestrates immune responses against pathogens, including Pseudomonas syringae bacteria. The timing and extent of SA accumulation are tightly controlled...

Plant biologist Lucia Strader joins Salk faculty to study plant growth signaling - Salk Institute for Biological Studies LA JOLLA—The Salk Institute will welcome plant biologist Lucia Strader as a new professor and holder of the Howard H. and Maryam R. Newman Chair in Plant Biology in October 2025. Strader is an interna...

The lab is moving to the Salk Institute! We are thrilled to join an inspiring community where we will continue to explore plant growth and development.

Deep gratitude for the years of support and collaboration at Duke/NCSU/UNC.

Thrilled to have our spatial single-cell atlas of the Arabidopsis lifecycle in @NaturePlants. Turns out that its easy to make nice images when spatial expression of 1,000 genes is available! 1/n

Congratulations Travis 😊 Nice work🎉

It’s one of the best feelings 🙃

Congratulations Natalia 🎉

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

Unlocking expanded flagellin perception through rational receptor engineering - Nature Plants Receptor kinase FLS2 detects the flg22 epitope of bacterial flagellin. Here the authors identify key residues on FLS2’s concave surface that enable expanded perception of flg22 variants, allowing the ...

Excited this paper is finally published! We focused on the inner concave surface of LRR RKs to expand bacterial flagellin perception in plants. Selection indicates expanded perception is more common than previously thought. Experiments led by @jerrytli.bsky.social www.nature.com/articles/s41...

Grateful to be at #2025ISMPMI! Reconnected with my former mentor @carogutj.bsky.social and met Maria, my current PIs mentor-so many cool stories🌱
Loved the energy at the poster session and great chats, including with Ertao Wang whose AMF work continues to inspire. #AMF

The latest publication from our lab!

The famous "glomalin" from arbuscular mycorrhizal (AM) fungi is not a protein but a polysaccharide from AM fungi, so we renamed it "glomalose". Glomalin-related proteins are bacterial proteins stuck in this glomalose.
