Not something you see in textbooks very often: tripolar mitosis.

Save the Date: World Petunia Days 2026! Join us in Rome, June 3-5, for an inspiring scientific gathering amidst historic landmarks. Exchange innovative ideas in a collegial atmosphere. More details coming soon! We can't wait to welcome you to the Eternal City. #WPD2026 #Rome #ScienceMeetsHistory

This is worth reading! A beautiful testimony of remembering why we chose to do science in the first place: curiosity and excitement, not pressure to publish and secure grants. Even if the research system always tells us otherwise!

In celebration of #BlackHistoryMonth let’s learn more about Marie Taylor, a plant biologist and chair of Howard University’s Botany Department. Love her focus on photomorphogensis and using light microscopy on living plants! 🌱 en.wikipedia.org/wiki/Marie_T...

The August issue is now fully online, with a beautiful cover that might be a nostalgia trigger for some of us (young people can find an explanation in the Editorial): www.nature.com/nplants/volu...

Out in @science.org this week: SIPS binds to a conserved region of SRK to control interspecies incompatibility in Brassicaceae. This contrasts with SRK's variable region, which is involved in self-incompatibility interactions. www.science.org/doi/10.1126/... #plantscience

@yu1cheng.bsky.social, in collaboration with Filip Kolar and me, published an article looking at how the genetic architecture of unreduced gametes and environmental factors can affect autopolyploidy evolution. Congrats Yu! www.nature.com/articles/s41...

Très belle introduction à l'étude de mes collègues lillois @crouxevo.bsky.social, François Monnet, @zopos.bsky.social, Christelle Fraisse Xavier Vekemans et Pascal Touzet, qui remet en question une idée reçue -mais fausse- sur l'évolution des plantes. www.inee.cnrs.fr/fr/cnrsinfo/...

Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)

Super great time at @popgroup2026.bsky.social in Lille 👉 presenting lab postdoc work, reconnecting with colleagues worldwide & exchanging inspiring ideas! Huge thanks to organizers @vincentcastric.bsky.social, @crouxevo.bsky.social, Diala Abu Awad @thomaslesaffre.bsky.social, @romanstet.bsky.social

Really enjoyed @thomaslenormand.bsky.social explain the unified theory today at @popgroup2026.bsky.social in Lille: inspiring, thought-provoking, and very timely 🧠🤯✨ Reposting his post on the paper here: highly recommended read! #evolution #sexchromosomes #largeXeffects #haldane'srule #speciation

I’m in this meme and I don’t like it. #academicsky #academiclife

Let's get started !

Looking forward to welcoming everyone in just two days now... Check out the latest updates to the program at populationgeneticsgroup.org.uk

"I don’t know why my fellowship was terminated. I suspect that it has something to do with studying a species that doesn’t fit the binary of what we expect to see in nature, with completely different males and females." @carlzimmer.com profiles my wonderful coauthor @jjinsing.bsky.social Gift link.

A new community-driven lab handbook for reducing conflict and creating more positive and equitable work environments gets strong support from a survey of 200 researchers. buff.ly/K7CGFLV

This story is absolutely wild. Did you know that avocados change sex over the course of a day? And that it's controlled by a single ancient balanced polymorphism? This is flat our crazy

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.

🔥 Hot new preprint before the Christmas break 🎄 Egg cell fertilization–dependent peptide receptor signaling mediates endosperm polarity 📖 www.biorxiv.org/content/10.6... Audrey Creff, @jackrhodes.bsky.social , Cyril Zipfel, Gwyneth Ingram and others

We're having a most fulfilling collaboration across the fields of evolutionary & structural biology with @marclensink.bsky.social and @bonsaiseqbioinfo.bsky.social, and would love to host new colleagues through this national call ! Get in touch if interested

Today is probably the only day of my life when I have submitted TWO PAPERS! Well it's the only two ones in two years but still! 🤩

Full room at #Evo-Eco-Paleo in for the defense of Camille Jolivel's PhD thesis on pollinator-mediated selection in dioecious plants in natural and urbanized habitats. 🐝〰️🥀 🤩 Detailed dissection of the ecological processes and selection gradients ! @cnrsecologie.bsky.social @univlille.bsky.social

🧪🌱 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

Today, our Director, Gwyneth Ingram, received the CNRS Silver Medal. (👇see the post below👇) This award recognizes researchers for the originality, quality, and significance of their work, acknowledged at both national and international levels. 🌱Congratulations!🥂

👇 New preprint from the lab on cell layer identity in petunia flower 🌸 ▶️Interplay between petal identity and cell layer identity in petunia flower Lead by @mariemonniaux.bsky.social now located in Lille, .univ-lille.fr/en/research/... and Daniel Bouyer 👇👇

I like the idea of "resurrecting" forgotten crops using modern technology. Pádraic Flood's new startup Aardaia does this. "The aardaker is a forgotten food, [...] ‘It was cultivated in Zeeland in the 18th century! And it has a lot of potential. [...], it contains a lot of protein" #PlantScience

Your periodic reminder that science is not done by a few selected "stars scientists". Science is done by hundred of thousands. Siloed money mean a few flashy discoveries and a lot of waste. Want to change things? Make funding accessible and stop funding calls with less than 2% success rate.

"Runctitiononal features"? "Medical fymblal"? "1 Tol Line storee"? This gets worse the longer you look at it. But it's got to be good, because it was published in Nature Scientific Reports last week: www.nature.com/articles/s41... h/t @asa.tsbalans.se

I just published: Adeline Harant: Keeping an open mind is key for a fulfilling career in science A much-deserved tribute to the amazing Adeline Harant and her leadership at the bench and beyond. She also brings a dose of sanity to the @KamounLab madhouse. kamounlab.medium.com/adeline-hara...

Oh, wow. Heritable chromosome fusions! Amazing. www.science.org/doi/10.1126/...

warwick.ac.uk/fac/cross_fa... I also have a plant evo-devo PhD opportunity open to study the evolutionary origins of female meiosis with me ^^. Deadline Thursday 27th November, so if you know anyone who might be interested, please do let them know! #Plantscience

I recently moved my lab to Purdue University and am looking for graduate students. We are working at the interface of population genomics, quantitative genetics and functional genomics to understand how plants adapt to extreme environments. Reach out if you would like to discuss potential projects.

Hi Folks ! Just a few more days to register for the POPGROUP meeting (deadline = this Monday 10/11/2025). Join us in the beautiful city of #Lille just across the Channel for three exciting days of science and more ! www.hautsdefrancetourism.com/destinations... --> populationgeneticsgroup.org.uk
