Transcriptional repressor involved in abiotic stress responses. Can repress the stress responsive genes DREB1A and LTI78. Probably involved in jasmonate (JA) early signaling response. May regulate the expression of the JA biosynthesis gene LOX3 and control the expression of TIFY10A/JAZ1, a key repressor in the JA signaling cascade. Expressed in roots, stems and leaves. By salt, cold and drought stresses. Down-regulated by gibberellin. Plants overexpressing ZAT10 show growth retardation and enhanced tolerance to drought, salt, heat and osmotic stresses. Plants silencing ZAT10 show enhanced tolerance to salt and osmotic stresses.
