bioRxiv:Β Plasma membrane nanoscale dynamics of Arabidopsis leucine-rich repeat receptor kinase complexes (2026) Plasma membrane-localized receptors operate as dynamic signaling complexes and integrative networks, yet the spatial and temporal regulation of these interactions remain largely unknown. Here, by analyzing the components of a minimal Arabidopsis leucine-rich repeat receptor kinase network, we describe the differential diffusion and organization of receptor complex components and unveil the nanoscale spatial and temporal logic underlying the formation of receptor kinase complexes. The ligand-binding receptors FLS2 and BRI1, and the accessory receptor BIR3, are organized in plasma membrane nanodomains, within which the co-receptor BAK1 diffuses and is spatially arrested upon ligand perception. BAK1 spatial arrest relies on extracellular domain (ECD)-ECD interactions but does not require receptor complex activation. Mathematical modelling, single molecule imaging and bio-assays infer that accessory receptors maintain a dynamic pool of co-receptors in the vicinity of ligand-binding receptors to promote ligand-induced complex formation and signaling. We propose that ligand-induced receptor kinase complex formation is a deterministic process defined by the relative nanoscale spatial positioning of individual signaling and regulatory components.

Happy to share our latest work in collaboration with the lab of @pengbo10.bsky.social. Here, we describe that a formin protein mediates the polarity switch from root hair to infection thread growth during symbiotic interactions.

Indeed. New grants are not getting funded, already funded grants are not getting paid, and non-competitive renewals are being held up.

Focusing on the top line budget, instead of looking at what is really happening on β€œthe ground” is deeply misguided.

Preprint!!!! This is the result of an ongoing collaboration between us and the genomics core to make genetics cheap and easy. A synergy between library prep and analytical approaches. This one hinges on recognizing 1. that DNA molecules are shaped by evolution and 2. we have friends everywhere.

They probably have a competing story and are dragging your paper along until theirs is ready. Happened to me 2x. This is why preprinting is great. Establishes priority and everyone can see the record.
