🌱In unserem letzten Beitrag zum #fascinationofplantsday erklärt André Marques @amarques.bsky.social vom MPIPZ @mpipz.bsky.social was eine erfolgreiche Pflanze ausmacht und welche Rolle unterschiedliche Chromosomen dabei spielen können. Wirklich faszinierend! 😉

Hot off the press 🚨 Epidemic spreading between regions is often modelled on a network 🕸️ But how do we describe this process properly? Here, we show how to build a linear transport operator at the network scale, by coarse-graining local advection-reaction-diffusion within edges. shorturl.at/0tAN8

A multiscale theory for network advection- reaction-diffusion - Journal of Mathematical Biology

Mathematical network models are extremely useful to capture complex propagation processes between different regions (nodes), e.g. the spread of an infectious agent between different countries, or the transport and replication of toxic proteins across different brain regions in neurodegenerative diseases. In these models, transport is modelled at the macroscale through an operator, the so-called graph Laplacian, based on the edge properties and topology, capturing the fluxes between different nodes of the network. However, this phenomenological approach fails to take into account the physical processes taking place, at the microscale, within the edge. A fundamental problem is then to obtain a transport operator from mechanistic principles based on the underlying transport process. Using advection-reaction-diffusion as a generic mechanism for inter-nodal exchanges, we derive a multiscale network transport model and derive the corresponding linear transport operator at the macroscale from first principles. This effective graph Laplacian is fully determined by the transport mechanisms along the edges at the microscale. We show that this operator correctly captures the transport, and we study its scaling properties with respect to edge length.

Great to see this really cool story published in Nature! rdcu.be/e7UoR Parker & Wang’s commentary, “A fellowship of the rings in plant defence”, provides further insights into the elaborate structures of NLRs formed during plant immunity. rdcu.be/e7UnA @nature.com @mpipz.bsky.social

Assembly of helper NLR resistosome clusters upon activation of a coiled-coil NLR

Nature - SUMM2, a coiled-coil NLR, promotes the assembly of higher-order resistosome clusters to initiate cell death in plants.

🥔 We traced the ancestral legacy of modern breeding introgressions in European potato! Combining pedigree records & genome-wide SNPs, we reveal which wild relatives shaped the European gene pool and how. 📄 doi.org/10.1007/s00122-025-05143-z

Tracing modern breeding introgressions in European potato - Theoretical and Applied Genetics

The European potato germplasm originated from a few founding genotypes, and its narrow genetic base has since been broadened through introgressions from wild relatives. We combined pedigree records an...
