Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. https://scim.ag/4nTQ3nq

Excited to see the structurally conserved nucleoside hydrolase like fold that we found (elifesciences.org/articles/105...) to be conserved among biotrophs now being experimentally validated to target EDS1 !! Link to the preprint - www.biorxiv.org/content/10.6...

Proud to share our new paper on how prion-like fungal effectors target plastids and modulate host metabolism during root symbiosis. Exciting collaborative work uncovering PEPSI effectors and the interaction of one of them with DXR in plants. www.biorxiv.org/content/10.6... bsky.app/profile/eell...

Check out our latest work! AlphaFold 3 revealed a transient immune receptor complex that eluded biochemical studies for almost a decade 🤯 We describe a conserved structural logic underlying sensor–helper communication in an NLR immune receptor network 🧵👇

We are excited to release the BAT!🦇🚨 We've used this phylogenetic analysis pipeline in our lab for years, and grad Ben Sheppard now presents a Github release and preprint. I run BAT analyses almost daily. It makes exploring gene families routine, customizable, and fun🧵

Hey #MPMI crowd, we are having trouble finding co-proteome papers looking into the host and pathogen proteome at the same time. I know they must exist but can’t find them. Any suggestions?

Resequencing hundreds or thousands of individuals from the same species has become routine... but processing all those genomes efficiently? Still a headache! Here's my solution that used to be lab-internal but that I am happy to share: crolllab.github.io/genomepanel_...

Very excited to see this work out today! Discovering viral immune antagonists directly from predicted protein structures. 🤩 www.science.org/doi/10.1126/... Huge thanks to the amazing collaborators! 🤗

Plant weirdness. After injecting agro rhizogenes into the stem of Kalanchoe, they start sprouting roots from stem after few weeks later.

Is the lesson from this that, if ones reasoning is freed from the pull of gravity, one can still publish with MDPI?

@thaisdalsasso.bsky.social is applying new tools to address the evolution and functional diversification of secreted proteins of fungal plant pathogen. Preprint here: www.biorxiv.org/content/10.6...

What we more recently learnt about Tiberius: the models trained on softmasked genomes are very sensitive to how the genome was masked for inference. It seems safer to use models trained on unmasked genomes. #genomeannotation #geneprediction github.com/Gaius-August...

Out in @NaturePlants. We discover that the fungal pathogen Fusarium graminearum secretes an apoplastic effector that disrupts the N-glycosylation of a maize immune receptor, thereby inducing its degradation via selective autophagy. Very proud of the team~ doi.org/10.1038/s414...

This article is now published! academic.oup.com/nargab/artic... We’ve added a few new analyses. First off, we show that, while gene presence absence variation (PAV) scales with evolutionary distance in both plants and animals, the base level and rate of accrual are both twice as high in plants.

📣 Our lab is seeking a postdoc to study mutation mechanisms in fungi using cutting-edge sequencing + computational biology. No active posting/grant right now, but we’re excited to host postdoc fellowship applicants in our comparative immunology team. Interested? Reach out DM email. krasilevalab.org

Ever wondered if diverse plant species respond similarly when infected by the same exact pathogen? Infect different asterids and rosids with the same Botrytis genotypes and teh short answer, quite differently. www.biorxiv.org/content/10.6... @annajomu.bsky.social @ccaseys.bsky.social (1/3)

Although it went online in 2025, here is our second paper of 2026! 🎉 Bravo to @jiaxuwu.bsky.social for leading this (possibly) controversial, but much-needed, analysis. Enjoy! Now out in the January 2026 issue of Trends in Genetics. 🔗 www.cell.com/trends/genet...

Comment in @nature.com: "Food will be more affordable — if we double funds for agriculture research now" www.nature.com/articles/d41... A global drop in public and private investment in agricultural science in the past four decades is partly to blame for high food prices, an analysis reveals.

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen. 1/n

New preprint! 🐛 Root-knot nematodes hijack root cells, turning them into feeding sites and making plants very sick. Using a cross-species scRNA-seq approach we mapped this process and show how this knowledge can be used to engineer resistant crops.🌱 A summary🧵 : www.biorxiv.org/content/10.1...

Today's going exceptionally well 😅. Our paper describing the screening of Arabidopsis natural accessions against a Canadian clubroot pathotype is out now!

Glad to see this out! We discussed the confusion around the ever-growing list of clubroot resistance genes and what truly qualifies as the novel ones. The clubroot community needs a consistent nomenclature to keep track of the real progress. @jiaxuwu.bsky.social , @edelplopez.bsky.social

Happy to see this out! @jiaxuwu.bsky.social, @sohambio.bsky.social & I tackle the growing confusion in clubroot resistance gene naming. We call for a common nomenclature and a shared database to speed up durable resistance 🧬 🥦 Thank you @cp-trendsgenetics.bsky.social for a great editorial process!

📣 NEW PREPRINT 📝 We identified evolutionary origins of many fungal effectors! We show that fungi secrete lots of antimicrobial proteins, and that some of them were repurposed by plant pathogens for host immune suppression. www.biorxiv.org/content/10.1... cc @teamthomma.bsky.social

We wrote a review on the free nucleotide pool as a central playground in human, bacterial, and plant immunity – now out in Nature Reviews in Immunology www.nature.com/articles/s41... Was fun to write this piece with Dina Hochhauser! Here is a thread to explain the premises 1/

Wow - an important component of a central human innate immune pathway was discovered based on homology to a bacterial anti-phage defense system A beautiful example showing how new knowledge on bacterial immunity translates to discoveries important for human health
