Protein-templated synthesis of dinucleotide repeat DNA by an antiphage reverse transcriptase Defense-associated reverse transcriptases (DRTs) are widespread bacterial anti-phage systems that use unconventional mechanisms of polynucleotide synthesis. We show that DRT3, which comprises two dist...

PELOTA at the Crossroads of Ribosome-associated quality control and Silencing: Coordinating Development, Stress, and Immunity in Plants Abstract. Ribosome-associated quality control (RaQC) pathways, including no-go decay (NGD) and non-stop decay (NSD), are essential for maintaining translat

❗️Excited to share our new review in J Exp Bot on PELOTA and ribosome-associated quality control in plants 🌱

We explore how translation surveillance connects with RNA silencing, development, and plant immunity.

Great work by PhD student Gemma Sans-Coll 👏

Termination of the integrated stress response Stress responses enable cells to detect, adapt to, and survive challenges. The benefit of these signaling pathways depends on their reversibility. The integrated stress response (ISR) is elicited by p...

Answer to a key and longstanding question;
How does the integrated stress response terminate?

Giant DNA viruses encode a hallmark translation initiation complex of eukaryotic life Giant DNA viruses encode a cap-binding complex homologous to eIF4F, the defining translation-initiation complex of eukaryotes. The viral cap-binding complex is required for viral protein synthesis and...

"Here, we discover that giant DNA viruses encode a distinct and functional IF4F translation-initiation complex to drive protein synthesis, thereby blurring the line between cellular and acellular biology"

RNA splicing generates a functionally specialized Rep protein isoform in geminiviruses — enabling timely control of the viral cycle. Strikingly, similar strategies might have evolved in DNA viruses infecting different kingdoms: www.biorxiv.org/content/10.6... Spearheaded by @delphinem-p.bsky.social!

“La cura para todo es siempre agua salada: el sudor, las lágrimas o el mar.”

🔬 Ribosomes are hands down one of the most intricate molecular machines we know. Huge (for a cellular scale at least) complexes made of long RNAs (rRNAs) and proteins … a lot of different proteins.

It was great to collaborate with you @alonsostepanovalab.bsky.social , as always 🤩 Congrats, Jade, for an amazing job!
🌱🧬🩷

Just in time for Christmas a new paper in @plantspeopleplanet.bsky.social by @joannakacprzyk.bsky.social and myself.
We asked 421 plant scientists why they study plants!
Check it out and also check @plantmemories.bsky.social where we post lovely survey responses.

Ya está aquí la 5ª convocatoria del Concurso «Dibuja una persona que se dedique a la ciencia y ponle un nombre». ¡Anima a tus estudiantes a participar!

🗣️ Today, Rosa Lozano-Durán from the Center for Molecular Plant Biology (ZMBP), @unituebingen.bsky.social (Germany) came to visit us in Málaga to share her research with a great talk entitled “The Cell Snatchers -- viral strategies to hijack a plant” as part of our #IHSMLaMayoraSeminars

Avisa si está en su puesto! ☺️

How lucky are we?! 🤩 Rosa Lozano-Durán @geminiteamlab.bsky.social will be here!
So looking forward to hearing you, my friend!
🌱🦠

Congrats, Silvia!!!

Timing of transcription controls the selective translation of newly synthesized mRNAs during acute environmental stress Under stress, cells adapt their gene expression programs through changes in transcription and translation. It is unclear how cells determine which mRNAs are translated or repressed. Zedan et al. show that the timing of mRNA production alone determines the selectivity of translation, thereby coupling the processes of transcription and translation.

Metamorphosis is nature at its weirdest and historian Oren Harman has just written a beautiful book about it.
