We are offering a PhD project to explore how transcription factors have shaped the evolution of plant protective barriers.

We will support suitable candidates in applying to the @unistra.fr Graduate School competition.

Interested? Please get in touch for more information!

Thanks for your comments!
As you said, dehydration of spores must be not enough because I immediately put them into a freezer. They may be broken from inside because of water freezing in a spore.
Again, I appreciate your advice.

Another possibility comes up. I put spores into a refrigerator just after putting them into a tube with silica gel. Perhaps they may break from inside because of freezing…

I may find the cause of spore sterility... That may be high humidity of culture plate of Marchantia...

My colleague tells me that spores of M. polymorpha cultivated on agar medium are worse (not germinated etc...) than those on soil...... If so, my resource will be useless...

It seems to be fine that spore is stored at 4˚C, -30˚C or even -80˚C.

Perhaps, -30˚C was too harsh and 4˚C is appropriate...?

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.

Spiral phyllotaxis in the moss Physcomitrium patens emerges from simple division rules of the apical cell Cammarata et al. explore how cell division orientation generates phyllotaxis in moss with a unicellular meristem. They show that successive rotational divisions in the apical cell are precisely placed...

🎉 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.

Membrane topology inversion of GGCX mediates cytoplasmic carboxylation for antiviral defense Mitochondrial antiviral signaling protein (MAVS) is an adaptor involved in antiviral immunity, but its regulation is not fully understood. We identified carboxylation of MAVS by vitamin K (VK)–depende...

I listened to a seminar related to this work. Membrane topology inversion is very interesting.

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!

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.

Parts of gemma development and the timing to determine the dorsoventrality are especially interesting. Besides, I learned the importance of examining all three planes; frontal, sagittal, and transverse, to see a whole picture of gene expression pattern in 3D structure.

Very interesting work based on careful and precise observation. I like this and really learn a lot from this.
