We demonstrate that the LysM-RLK LYKa is essential for AM in Marchantia paleacea, thus an ancestral function given its orthologues requirement for AM in angiosperms ✅ (2/6)
COs and LCOs signalling also depends on LYR, which seems to be their true receptor. However, lyr mutants establish perfect arbuscular mycorrhiza… 🤯 (4/6)
Are other signals involved?! 🤔 A fun question for the next wave (5/6)
LYKa is required for chito- (COs) and lipochito-oligosaccharides (LCOs) signalling in M. paleacea, but it is not alone! (3/6)
