Produces a rapid alkalinization of the cellular media and the induction of defense-related genes, including chitinase 1b, chalcone synthase and CYP93A1. Not active in tobacco or Arabidopsis. The receptor for GmPep914 is probably different from the receptor for GmSubPep. Expressed in roots. Barely detected in flowers. Up-regulated by the GmPep914 peptide, ethephon, methyl jasmonate and methyl salicylate. The full-length coding region in cv. A3525 has been amplified by RT-PCR and sequenced, but not submitted to the EMBL/GenBank/DDBJ databases (PubMed:21478368).
