Movember is over, and LBM donned its finest moustache to take part in this event, which raises awareness of cancers affecting men.

Congrats to Matheus Montrazi who brillantly defended his PhD on Friday 🤩🍾🥂 on sphingolipids mediated interleaflet coupling in ROP6-auxin signaling www.biorxiv.org/content/10.1...
Thanks to Juliette Jouhet, @julien-gronnier.bsky.social , Soazig Guyomarch', @alexmartiniere.bsky.social, Derek McCusker.

Proud to announce you my graduation as Doctor in Cell Biology after my thesis defense. By revisiting the early secretory pathway in plant cells: identification of a dynamic tubulo-vesiculated ERGIC that mature in Golgi. Thanks to my supervisor @yohannboutte.bsky.social @lbm-bordeaux.bsky.social

LBM members were in Strasbourg to participate in the 20th GERLI International Lipid Meeting... good seminars and good discussions with colleagues from the lipid science community

#Agenda 📅 Rendez-vous ce soir à la Cité du Vin à #Bordeaux pour ces nouvelles Vendanges du savoir "Changement climatique : que nous dit la vigne ?", avec Iñaki Garcia de Cortazar Atauri, ingénieur agronome, directeur de l’unité Agroclim à l’INRAE Avignon.

Our work on mapping the dynamics of phospholipids during lateral root formation is now published in @jxbotany.bsky.social We show that PI(4,5)P₂ plays a key role: targeted reduction in pericycle promotes LR development.

Dear ENPER community, We are pleased to invite you to the next ENPER meeting, which will be held in my country Bulgaria, from 26 to 28 August 2026 in Sofia. Save the Date!🌱🌱🌱

Plants have a secret language that scientists are only now starting to decipher Signals from the plant cell wall help to orchestrate growth, reproduction and immune function. Can harnessing this molecular cross talk help in creating better crops?

Scientists long thought the plant cell wall to be dead, but it's an active, even chatty participant in cellular growth, reproduction and responses to infection

To mark Pink October, the month dedicated to raising awareness of women's cancers, LBM put together a team to take part in the Pink Ribbon Run. The aim was to raise funds to purchase equipment and provide high-quality care for patients.
Congratulations to all the participants!

The image shows several elongated rhomboid-shaped cells, filled with ovoid chrooroplasts in magenta, as well as a network of bubble-like vacuoles.

Here are some “leaf” or phyllid cells from moss Physcomitrium patens gametophore. Cells are expressing a green fluorescence marker that labels the vacuolar membrane. Chloroplasts' autofluorescence is in magenta.
Can you spot dividing chloroplasts?

🎉🔥 Yesterday, the IBMP team gathered for our annual BBQ! A perfect mix of sunshine, good food, and great colleagues. Thanks to everyone who joined and helped make it such a fun and delicious event! 🌞🍽️ #BBQ #LabLife

Summer clean-up goes hand in hand with a summer drink at the LBM!
The labs are glittering!

Canicule : causes et conséquences Canicule : causes et conséquences | CNRS Le journal

Canicule ! Le spectre des chaleurs extrêmes et de longue durée revient désormais à chaque été, voire dès le printemps. Voici un dossier pour mieux comprendre ces épisodes, leurs effets et le rôle du changement climatique dans l’implacable montée du thermomètre.

Plants monitor the integrity of their barrier by sensing gas diffusion - Nature A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social‬ @erc.europa.eu‬ 1/x 🧵 www.nature.com/articles/s41...
