Schematic diagram showing the relationship between cGMP, the plant hormone giberellic acid (GA), nitric oxide (NO) and induction of gene expression in plant cells. Both GA and NO can induce increases in cGMP levels which in turn stimulate specific transcription factors (TFs) to induce gene transcription. The interaction of cAMP with cGMP is less well understood in plants so the induction of cAMP production is indicated by a question mark (?) and dashed lines.
