Auxin and cytokinin signaling pathways are under protein S-nitrosylation influence. Overview of indole-acetic acid (IAA) and cytokinin (CK) signaling pathways. S-nitrosothiols are represented by an SNO mark. Protein phosphorylation is represented by a P letter. References to physiological processes regulated by hormones, and subcellular localizations are also indicated. TIR1, transport inhibitor response 1 protein; Aux/IAA, auxin/indole-3-acetic acid protein; ARF, auxin response factor; Ub, ubiquitin; AHKs, hybrid histidine protein kinases; AHP1, histidine phosphotransfer protein 1; ARR-B, primary response regulator type B.
