Last month marked the end of my time at @PetrasekLab at @UEBavcr in Prague. Huge thanks to everyone there for the support, guidance, and the wonderful family-like atmosphere!
Symplastic auxin flow shapes branching of moss gametophores!
I was happy to contribute to this exciting work of Jeanne and Yoan.

It’s been a long but exciting journey — a few days ago I successfully defended my PhD thesis on the evolutionary origins of auxin action, carried out in the Petrášek Lab.
Huge thanks to @Isabel_MonteG and @Bishopp_Lab for coming to Prague and for being such wonderful reviewers!

📣A new preprint from our group!
No, this is not an image of some strange octopus but an anti-CbPINa staining in the antheridial filament of streptophyte alga Chara braunii. If you want to know more about auxin and PINs in Chara check out it at: biorxiv.org/content/10.1101/…
[3/10: How?]
Focusing on sterptophyte algae, we used LC/MS and laser spectroscopy for a detailed phytohormone analysis, with comprehensive sampling strategy including not only biomass, but also culture media and control (blank) media, accounting for excretion and background.
[9/10: Prospects]
It seems that the biosynthesis of phytohormone compounds likely predated their recruitment in signaling and metabolism in land plants. If some of these compounds have any (signaling) role in algae, or how they came to become plant hormones remains to be found.
[10/10:]
We hope this work will serve as a stepping stone for such follow up research.

Some compounds we know as plant hormones are widespread in green algae.

Extremely thrilled to share that the Zygnema #genomes paper is now out @NatureGenet We hope that this will be a great resource for all #plantsci #algae @watertoland #evolution rdcu.be/dGnWJ
#EESPlantDiversity
What an amazing event at EMBL (Heidelberg), with lots of genomics and metabolomics in addressing plant diversity. I'm glad I could provide some insights from streptophyte algae.

Check out our latest review on Chara, a charming model organism for evo-devo studies and more! I really enjoyed contributing to this very nice work of @kat_kurtovic.
Excited to see our Chara review finally out! We summarize decades-long research and new insights into the molecular biology of this fascinating relative of land plants.
