Prediction of BRI1 signaling output in the absence of SERK coreceptors. The signal intensity of BRI1 (σ) is predicted in the presence or absence of SERK1 and SERK3. The signal transduced in serk3-2 and serk1-3 mutants is computed by plotting α₃C₃^a (σ SERK3) and α₂C₂^a (σ SERK1). For the signal in the serk1-3serk3-2 mutant, the term α₁C₁^a was computed, representing the residual responses to BL. Col-0, Wild-type ecotype Columbia.
