In plants, extracellular signals are primarily sensed by plasma membrane-localized receptor-like kinases (RLKs). ERECTA is a leucine-rich repeat RLK that together with its paralogs ERECTA-like 1 (ERL1) and ERL2 regulates multiple aspects of plant development. forms complexes range co-receptors senses secreted cysteine-rich small proteins from the EPF/EPFL family. Currently mechanism cytoplasmic domain activation transmission signal unclear. To gain better understanding we performed...
