A molecular ‘gatekeeper’ in plants opens the door for beneficial microbes CIBSS researchers at the University of Freiburg are part of an international team that sheds light on a crucial step in the initiation of the symbiosis between plants and soil bacteria.

📢 #CIBSS research highlight!

Prof. Dr. Thomas Ott @ottlab.bsky.social helped identify SYFO2, a protein that lets legumes 🫛☘️“open the door” to nitrogen-fixing bacteria. 🦠 The team even activated it in tomato 🍅 — suggesting this symbiosis could be engineered in new crops. 🌱

Today's lycopsids ("clubmosses") are small plants and do not produce wood but some of their Paleozoic relatives did! This is a detail of the wood cells in a stem of Sigillaria from the Carboniferous of the USA 🔬🌿⛏️ Happy #FossilFriday!

We probably don't often plan to snack on tree bark, but we certainly do. Cinnamon is tree bark. There are five species of cinnamon from different geographical locations with distinctly different flavor profiles. This one is Cinnamomum verum, Sri Lankan cinnamon. Eat some bark today!
