Sequence of the Nicotiania tabacum rapid alkalinization factor (RALF) peptide (NtRALF). The underlined region represents the predicted signal peptide and the arrow indicates the point of cleavage by a subtilisin‐like serine protease (Srivastava et al., 2009). The sequence in red represents the active RALF peptide. Asterisks (*) denote the essential YSIY motif. Cysteine residues required for disulphide bond formation and RALF peptide activity are denoted by hashtags (#) (Pearce et al., 2010).
