Nanodomain-localized formin gates symbiotic microbial entry in legume and solanaceous plants Colonization of plant roots by symbionts requires substantial morphodynamic reorganization. Examples are actin-scaffolded microcompartments called infection pockets formed during root nodule symbiosis...

Happy to share our latest work in collaboration with the lab of @pengbo10.bsky.social. Here, we describe that a formin protein mediates the polarity switch from root hair to infection thread growth during symbiotic interactions.

Well, legumes cannot be the cover image on all journal issues... So, this is what happens, if you link the article to the post.

Congratulations, Jan!

The Lotus japonicus alpha‐expansin EXPA1 is recruited during intracellular and intercellular rhizobial colonization The colonization of legume roots by rhizobia represents a critical phase in the establishment of root nodule symbiosis. In this study, we demonstrated that LjEXPA1, a plant protein involved in cell w...

Now out: The expansin EXPA1 is required for both inter- and intracellular infections of Lotus roots. The study was led by Jesús Montiel (UNAM, Mexico) and Jens Stougaard (Aarhus, Denmark) with @blace.bsky.social from our team doing lots of the imaging.
