RLKs and MAPK cascades regulate reproductive and stomatal development. ERECTA family (ERf) members and MPK3/6 modulate anther development via activating the transcription factor SPOROCYTELESS (SPL) (A). HAESA/HAESA-like 2 (HAE/HSL2) and coreceptor SERKs perceive the INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) peptide signal to control floral organ abscission by activating MKK4/5 and MPK3/6 (B). ERf, TOO MANY MOUTH (TMM) and SERKs form a receptor complex to sense the EPIDERMAL PATTERNING FACTOR 1/2 (EPF1/2) peptide ligands to control stomatal development and pattern via the YDA-MKK4/5-MPK3/6 cascade. BRASSINOSTEROID-INSENSITIVE 2 (BIN2) functions downstream of BRASSINOSTEROID INSENSITIVE 1 (BRI1) to repress the activity of YDA and MKK4/5 in controlling stomatal development (C). ER perceives the EPF-LIKE 4/5 (EPFL4/5) peptide signals to regulate inflorescence architecture via the YDA-MKK4/5-MPK3/6 cascade (D). ? represents the unknown RLK, MAPK or transcription factor.
