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...

Hello everyone! I am pleased to share information on the first ever Computational Structural Virology Symposium, conducted August 4th on zoom and highlighting work in this emerging field. You can register for this event here: forms.gle/CNiqskMwQEuV.... Please re-post!

I hope to see lots of plant virologists at the American Society for Virology Meeting. asv.org/2025/05/09/p...

How do plant viruses cause symptoms? Are these developmental alterations functionally relevant? Man Gao, Enmanuel, et al. found that TYLCV does so through a host-mimicking domain in its C4 protein, co-opting a plant protein family - to attract the insect vector! www.sciencedirect.com/science/arti...

Further attempts to stay positive and push the boundaries of X-ray imaging in plant biology, here's a maize root tip. Technical voxel resolution is 0.8um, field of view is about 1mm tall, using the 20X lens on my ZEISS Versa 520 XRM. @danforthcenter.bsky.social @zeiss-microscopy.bsky.social

Tweeps, please spread the word. We're still looking at recruiting a structural biologist (any level) to study plant-pathogen protein complexes especially in the context of coevolution. Direct inquiries welcome. Please include a cover letter. Applicant from US welcome? medium.com/@kamounlab/2...

#RNA #Virology 🧪 Check out our latest paper! We discovered why inserts in RNA viruses are unstable. RNA viruses have substructures with very specific thermodynamic properties. Hairpin inserts that have the same properties are also stable. So simple yet so profound! journals.asm.org/doi/10.1128/...

Update: The majority of Israelies feel helpless and just don't know what they can do to stop this government, that will soon be a full blown dictatorship. We've been protesting for ±3 years straight, and that's obviously not helping. Attempts to organize big strikes failed.

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬 But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯 Our new study reveals how retrotransposons invade the germline directly from somatic cells. www.biorxiv.org/content/10.1... A short thread 🧵👇
