We are happy to share a new preprint: After years of searching, we discovered that a lanthipeptide from the symbiotic cyanobacterium Nostoc punctiforme forms covalent oligomers. Even more remarkable, it promotes the intimate interaction with its host Blasia pusilla.

An Oligomeric Lanthipeptide from Nostoc punctiforme Promotes Host Association During Early Symbiosis with Blasia pusilla
Nitrogen-fixing Nostoc species form symbiotic relationships with diverse plants, yet the role of specialized metabolites in these interactions remains poorly understood. Here, we identify a previously...
