Probable component of the salicylic acid (SA) defense signaling pathway and pathogen-induced systemic acquired resistance (SAR) (Probable). May be involved in disease resistance against fungal pathogens (Probable). May be involved in tolerance to salt and osmotic stresses (PubMed:24407603). Highly expressed in leaves (PubMed:21973266). Expressed at low levels in roots and stems (PubMed:21973266). Induced by salicylic acid (SA) in roots, stems and leaves (PubMed:21973266). Induced by jasmonate in roots (PubMed:21973266). Induced by ethylene in roots and leaves (PubMed:21973266). Induced by salt stress, osmotic shock, cold stress and abscisic acid (ABA) (PubMed:24407603).
