Poplar CLE peptides promoting ectomycorrhizal symbiosis identified through genome-wide analysis of responsive small secreted peptides Trees use CLAVATA3/EMBRYO SURROUNDING REGION-related (CLE) peptides to promote ectomycorrhizal symbiosis, revealing an additional regulatory layer in tree–

🧡 New paper out in @PlantPhysiology! We asked: how do trees talk to their fungal partners during ectomycorrhizal symbiosis? Turns out, tiny secreted peptides play a big role. 1/
