CC   -!- FUNCTION: Cell signaling peptide that may regulate plant stress,
CC       growth, and development. Mediates a rapid alkalinization of
CC       extracellular space by mediating a transient increase in the
CC       cytoplasmic Ca(2+) concentration leading to a calcium-dependent
CC       signaling events through a cell surface receptor and a concomitant
CC       activation of some intracellular mitogen-activated protein kinases (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the plant rapid alkalinization factor (RALF)
CC       family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAD12022.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
