How should I keep spores of Marchantia polymorpha subsp. ruderalis? Although I have kept them at -30˚C for 1-2 months, they don't germinate so far.

We are hiring Tenure-track Assistant Professor and Curator in Bryology at Natural History Museum Denmark, Copenhagen. Duties are collection-based research, curation of >350.000 bryophytes, university teaching and public engagement. Deadline 23 March 2026. Start Jan 2027. lnkd.in/eEaXnNnb

Delighted to share our new preprint: "Evolution of moss leaf-like organs through variations in deeply conserved developmental principles." Led by Ph.D. student Wenye Lin from my lab @irbv.bsky.social , in collab. with Yoan Coudert (ENS Lyon) and Richard Smith (JIC). www.biorxiv.org/content/10.6...

🎉 Congratulations to Katarina Kuusk on her successful PhD defense at IBMP (Feb 3, 2026)! Her work bridges structural bioinformatics & plant molecular biology to unravel dynamic P450 metabolons in soybean. 🌱

Happy new year! I wish this year will become one of the best year for you! Me? I just do what I have to do.

I listened to a seminar related to this work. Membrane topology inversion is very interesting. doi.org/10.1126/scie...

Bryophytes hold a larger gene family space than vascular plants | Dong et al. (2025) Nature Plants rdcu.be/eKcyO This is definitely interesting and important to bryophyte research. I feel this way, but I haven't finished reading it yet. I have no idea when I will finish reading this paper. 😅

Wow! Bookmark has been introduced! Amazing!

How wonderful bryophytes are!

To gall researchers, the two papers of my previous supervisor have been out! I am very happy to somewhat contribute one of them. Please check it out! Parasitic-Plant Parasite Rewires Flowering Pathways to Induce Stem-Derived Galls | Udandarao et al. (2025) Plant Direct doi.org/10.1002/pld3...

To promote the collection, I’ve launched a designer clothing line where synthetic biology meets aesthetics. I will give out 100 free limited edition shirts to the first who retweet and order with their handle in the name! Available here → nickdesnoyer.com 🧵(6/7)

I went to Mt. Norikura at northern Japanese alps last weekend for TA works. The environment was very unique and many plants I’ve never seen were there. Going back to the base, I saw the dynamic changes of the vegetation from alpine zone to subalpine zone. It was a good experience for me.

Finally, I start my PhD research at Hiroshima University supervised by Dr. Shimamura! Bon voyage 🚀🚀🚀

Quick action!

Dear US colleagues, In response to the Trump administration, my university @univ-amu.fr is setting up a new program dedicated to welcoming American scientists wishing to pursue their work in France. There are several M$ in the budget. www.univ-amu.fr/en/public/ac...

Dear French and Japanese colleagues, mark your calendars! We are organising the bilateral France-Japan "Frontiers in Plant Biology" symposium. Date: November 19-21, 2025 Location: Strasbourg More information soon! #plantscience

Bonne année!

Ma amie est au Japon! Bienvenue dans mon pays! 🇯🇵

Given the recent advances in omics technologies and bioinformatics software, if I have enough money, I can do almost anything we want to do. Therefore I have to think hard and deeply about what is interesting, what is important, and what is what I want to dedicate my life to.

Ideally, is it possible to assign quantitative volumes to all factors controlling the development in whatever plants you are researching on? I want to use MorphoGraphX to reconstruct its complete development process in silico.
