The molecular mechanisms underlying mycorrhizal symbioses, the most ubiquitous and impactful mutualistic plant–microbial interaction in nature, are largely unknown.  Through genetic mapping, resequencing and molecular validation, we demonstrate that a G-type lectin receptor-like kinase (lec-RLK) mediates the symbiotic interaction between Populus and the ectomycorrhizal fungus Laccaria bicolor.  This finding uncovers an important molecular step in the establishment of symbiotic plant–fungal associations and provides a molecular target for engineering beneficial mycorrhizal relationships.
