A hidden brake on plant immunity: IBMP researchers show in @NatureComms that JAO enzymes make 11-OH-JA, not 12-OH-JA as long believed, redrawing the jasmonate catabolism map. 🌿

Think the proteasome & its regulation is highly conserved? Think again 🔄

Our new preprint, lead by @LanginGautier , reveals how gene expansion, regulatory diversification & stress-responsive specialization shaped the evolution of the proteasome in 🌱

Electron-light cavities called lacunae have long been observed inside sperm nuclei. Earlier studies suggested that they might contain proteasomes, but their molecular contents remained unresolved.

Kolata and colleagues specifically examined these cavities in cryo-FIB-milled human sperm by in situ cryo-electron tomography. The DNA-free lacunae were packed mostly with uncapped 20S proteasome cores; a small fraction carried PA200, and no nuclear 26S particles were detected. The clusters arise during the spermatid stage, as histones are replaced by protamines.

The advance is not that condensed sperm were thought incapable of protein degradation. It is the direct 3D identification of a long-observed structure as a proteasome-rich compartment. What these proteasomes degrade in mature sperm remains unknown.

New Comment: "Evolution and implementation of EU regulation on new genomic techniques" https://t.co/XRXQeEQ3x9

Regulation (EU) 2026/1388 on plants obtained by certain new genomic techniques and their products was finally adopted by the European Union on 17 June 2026.

🧬 Excited to share our new study in @NatureBiotech that improves the efficiency of targeted insertion of large DNA fragments. Placing a whole stretch of DNA precisely at a designated safe site is one of the most important operations in genome editing.

First nucleic acid ever sequenced was a tRNA in 1965, first complete crystal structure of a nucleic acid was solved in 1974 for a tRNA, and we still learn about tRNAs, paper with former IBMP PhD student Guillaume Hummel and coworkers:

ipSAE being single-handedly conceived of by @RolandDunbrack and it being the most useful binding affinity metric (tied with LIS) is still crazy to me
