A pair of LysM receptors mediates symbiosis and immunity discrimination in Marchantia.

Most land plants form symbioses with microbes to acquire nutrients but also must restrict infection by pathogens. Here, we show that a single pair of lysin-motif-containing receptor-like kinases, MpaLYR and MpaCERK1, mediates both immunity and symbiosis in the liverwort Marchantia paleacea. MpaLYR has a higher affinity for long-chain (CO7) versus short-chain chitin oligomers (CO4).

Comparative proteomic landscapes elucidate human preimplantation development and failure.
