Discover our little story showing that carbon availability promotes gemma cup formation via cytokinins and independently of KAI2-dependent signalling in liverwort. This shows how important the interactions between sugars and CK are for plant development.

Very happy to share this study in collaboration with @jaz-humphreys.bsky.social and @frannybarbs.bsky.social , with our little contribution, on the role of Ck on Sugar-mediated gemma formation @biorxiv-plants.bsky.social www.biorxiv.org/content/10.6...

Liverworts can clonally propagate by producing compact shoot structures called gemmae, which develop within basket-like structures known as gemma cups. It was previously reported in Marchantia nepalen...

Out today... From Bowman lab, MpARF2 is the first essential transcription factor to be described for meristem maintenance in Marchantia. Glad to have contributed to another paper with Eduardo. #plantsciences #evodevo www.sciencedirect.com/science/arti...

Really proud to share this review with my new team. We started off making an excel file with all the NPF substrates for ourselves and decided to turn ot into something useful for the community. It contains some methods and an evolutionary perspective.

A new fossil fungus discovered in Scotland shows evidence of plants and fungi sharing nutrients to survive on land.
The fossil, more than 400 million years old, offers hints about the origin of one of the greatest partnerships in the history of life on Earth.
