Great to see this really cool story (see quoted post) published in @newphyt.bsky.social! nph.onlinelibrary.wiley.com/doi/full/10.... Congratulations @laravdijck.bsky.social, @parkergroup.bsky.social! Plant-Scopoletin-Fungal Endophyte-Iron #PlantScience #Coumarin #PlantImmunity #PlantNutrition

How can we better understand the plant immune system? In my new @cp-cellhostmicrobe.bsky.social piece, I propose “immune cell states” as a framework for uniting molecular and cellular perspectives. www.cell.com/cell-host-mi...

Fascinating innate immune evasion strategy in SCIENCE #glycotime 𝘗𝘴𝘦𝘶𝘥𝘰𝘮𝘰𝘯𝘢𝘴 𝘴𝘺𝘳𝘪𝘯𝘨𝘢𝘦 makes GLYCOSIRIN, a novel iminosugar that blocks plant glycosidases from degrading bacterial flagellin—hiding pathogens from plant immune sensors. New cryo-EM insights reveal exactly how this stealthy trick works

Would you like to study metabolite-based microbe-microbe or plant-microbe interactions but do not have the tools to? @chesneau-g.bsky.social came up with a simple solution with great potential! Check out our new publication in @naturecomms.bsky.social and Guillaume’s 🧵 below for details👇

📣Paper Alert! 📣New publication out by @hacquardst.bsky.social and his team on the development of MetaFlowTrain – a new tool to study metabolic exchange and interactions within microbial communities @naturecomms.bsky.social 👏🥳Congratulations! 👉https://bit.ly/44jnM1H www.nature.com/articles/s41...

We present MetaFlowTrain, an easy-to-build, highly parallelized, and cost-effective fluidic system for studying microbial exometabolites and their roles in modulating microbe–microbe–host interactions. Kudos to @chesneau-g.bsky.social @mpipz.bsky.social Give it a try: www.nature.com/articles/s41...

How did horses become so athletic? In part, a mutation that should have cut a key protein short instead makes it more sensitive to the stress of exercise. That and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪🐴

Finally! Im so excited to present to culmination of many years of work from the fantastic Defeng Shen and some great collaborators. For details, I have made a digested thread below, but if you are more interested feel free to reach out (and read the paper of course). www.science.org/doi/10.1126/...

📣Paper Alert! New publication @science.org by the group of @tonnigrubeandersen.bsky.social @mpipz.bsky.social, colleagues @ucph.bsky.social & others on the Casparian strip and its role in metabolic trade between plants & bacteria. 👏Learn more 👉https://bit.ly/4bJe4Yd www.science.org/doi/10.1126/...

We're looking for a postdoc to join the lab to work on cell-to-cell communication via the apoplast. Candidate must be brave, as they will have to lead us (me) away from the plasmodesmata-lands we've inhabited for so long! www.jic.ac.uk/vacancies/po...

Poke bacteria with a sharp needle and they poke back in just a few seconds! Congratulations to Mitchell (and others) for this analysis of Pseudomonas #T6SS assembly in response to membrane damage! Collaboration with Rod Lim's lab @biozentrum.unibas.ch www.science.org/doi/10.1126/...

Wow, cAMP production appears to be the key for activating canonical auxin signalling, not AUX/IAA degradation! Also annoying - I need to revise quite a many teaching slides to update auxin signalling 😀 www.nature.com/articles/s41...

🚨New paper published in @nature.com! Using pan-genetics across the Solanum genus🍅🥔🍆we reveal why gene duplications🧬are major contingencies in crop engineering. My postdoc work in the Lippman lab @CSHL, collab. with @katiejenike.bsky.social @mikeschatz.bsky.social chatz.bsky.social and many others!

I'm very happy to report that Matt Schechter's PhD work is now online as a pre-print: "Ribosomal protein phylogeography offers quantitative insights into the efficacy of genome-resolved surveys of microbial communities", www.biorxiv.org/content/10.1... Here's a little 🧵 about it.

Inspired by @mads100tist.bsky.social I'm going to do threads on parts of the publishing process we often get asked about. These will be from my perspective @naturecomms.bsky.social and based on my own opinions, so keep your salt handy.

The data is in. 2024 was the warmest year on record, and probably in the whole of human history – about 1.6°C warmer than the pre-industrial period. More than 1 billion individual thermometer measurements have been condensed into a single vital number. theconversation.com/my-new-dark-...

The protein GAME15 is the missing link in the pathway that Solanum plants like potatoes use to make molecules for pest defense, a new Science study finds. The results pave the way for innovative applications in agriculture and biotechnology.
