Thank you @scienceslam.de for this wonderful night in Hamburg! 👩‍🔬🎤 I had a blast, learned a lot and thoroughly enjoyed slamming about vertical transmission of plant viruses 🦠💚

Organelles do NOT have a single uniform pH. And if you think they must, because “protons diffuse fast,” this paper is for you. A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

The Clavel Group is recruiting a new postdoc for two possible projects dealing with plant-virus interactions and selective autophagy! More (wordy) details below ⬇️🌱🦠

🧪🌱 Sooo… our paper on how SPOROCYTELESS/NOZZLE controls the onset of megasporogenesis is finally out in @natcomms.nature.com 🎉🎉! This is one of the major projects of my postdoc at #LuciaColombo’s lab at #UniMI. www.nature.com/articles/s41... 🧶 1/7

🧬 TECHNICAL INNOVATION 🧬 CRISPR/Cas technology is an emerging tool for identifying nucleic acid sequences. Hak et al. present a user-friendly, extraction-free, rapid protocol for specific on-site detection of plant viruses using CRISPR/Cas13a. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Have you ever wondered how it is possible that systemically infected plants produce (a certain percentage of) healthy progeny? 💚 Check out the first preprint of the @incavirus.bsky.social lab and first preprint of my postdoc! 🍀 We'd be very happy about feedback and discussions!

Glad to have this finally published: www.sciencedirect.com/science/arti... lots of new data since the #preprint. If you are into selective #autophagy, #evolution, #proteostasis Please have a look!

It's great to see this work finally out! @newphyt.bsky.social Here we showed that auxin production after fertilization is a conserved, paternal-triggered mechanism for seed initiation in angiosperms.

In vivo RNA structure influences the translation and stability of plant long noncoding RNAs #research #PlantCommunications cell.com/plant-commun...

Check out our latest paper on mirusviruses, one of the most remarkable new groups of protist viruses - extremely diverse, carry lots of spliceosomal introns (including new homing introns) and are at the evolutionary crossroads between tailed phages and herpesviruses! www.nature.com/articles/s41...

Great talk by @delphinem-p.bsky.social from @geminiteamlab.bsky.social yesterday: “Hijacking the Plant #Spliceosome” on how alternative splicing drives #viral infection and #tomato fruit development 🍅 Thanks to our host @incavirus.bsky.social for organizing this insightful seminar! 👏

Looking for a #PhDposition in #PlantScience ? Our #IMPRS @mpi-mp-potsdam.bsky.social and @unipotsdam.bsky.social is #hiring ! 📅 Apply by 10 January 2026 More info: 👉 www.mpimp-golm.mpg.de/IMPRS-PhD Please share this post to plant it in the right feed 🌱 #PlantSciJobs

And now we have Arabidopsis plants with 8 chromosomes instead of 10 and no obvious phenotypic differences, this week in @science.org #PlantScience Paper here: www.science.org/doi/10.1126/... Perspective here: www.science.org/doi/10.1126/...

TEs aren’t just genomic parasites, they’re also engines of genomic novelty. Our new study with ~2,000 Z. tritici genomes shows repeated TE mobilization waves during global expansion. With @danielcroll.bsky.social & @guidopuccetti.bsky.social 🧬 www.nature.com/articles/s41... #TEworldwide

Excited to share our latest work on the factors that determine what genes we find (and don't find!) in GWAS and burden tests. We describe a critical concept that we call *specificity*. Led by Jeff Spence and Hakhamanesh Mostafavi:

How many plant species are buzz pollinated? After more than six years in the making, our paper on the convergent evolution of buzz pollinated flowers is out in @journal-evo.bsky.social. Thanks @draverbee.bsky.social @roszenil.bsky.social and all co-authors for your hard work! doi.org/10.1093/evol...

News for mushroom lovers: With the Flora Incognita app, you can now identify numerous #mushroom species in Central Europe based on images. These results can give you a good initial indication of what you have found 🍄 😱https://floraincognita.com

It was wonderful to have Bijun with us @mpi-mp-potsdam.bsky.social & @incavirus.bsky.social to finally "use our microscope to its full potential" as our core-facility put it! 🔬 Congrats to all, esp. @bijuntang.bsky.social and @xanderjones.bsky.social ! Super happy to be a part of this great story!

How do geminiviruses maximize their limited coding capacity? Our recent preprint uncovers splicing of viral transcripts as one more strategy used by this viral family. We show that RNA splicing is prevalent in the geminivirus TYLCV — and required for infectivity! www.biorxiv.org/content/10.1...

Historically, viruses were thought to primarily use host cell's translational machinery. New work from @harvardcellbio.bsky.social faculty Amy Lee reveals that a giant DNA virus encodes its own IF4F initiation complex, suggesting an unexpected evolutionary innovation. www.biorxiv.org/content/10.1...
