NO-dependent changes in the expression of genes related to GA metabolism and signalling in seeds.

	Gene	Changes in Gene Expression	Plant Material	General Description of the Material and Results	References
Biosynthesis	GA3ox2	↓	Hedge mustard seeds	Downregulated at 3, 6, 22, and 26 h of imbibition of non-after-ripened seeds in 20 mM KNO3.	[80]
	GA20ox2	↑↓		Upregulated only at 3 h and downregulated after 6, 12, and 26 h of imbibition of non-after-ripened seeds in 20 mM KNO3.
	GA2ox6	↓		Downregulated after 22 and 26 h of imbibition of non-after-ripened seeds in 20 mM KNO3.
	GA3ox2	↑	Hedge mustard seeds	Stimulated by 20 mM KNO3, especially at 22 and 26 h of imbibition of 7-months after-ripened seeds.	[81]
	GA20ox2	↑		Upregulated between 6 and 26 h of imbibition of 7-month after-ripened seeds treated with 20 mM KNO3.
	GA2ox6	↑
	GA3ox1	↓	Arabidopsis seeds	CN− alleviates the dormancy of Arabidopsis seeds. Seed treatment with 200 µM cPTIO reduced gene expression compared with single CN− application.	[85]

Signalling	RGL2	↓	Hedge mustard seeds	Downregulated after 22 and 26 h of imbibition of non-after-ripened seeds in 20 mM KNO3.	[80]
	RGL2	↓	Hedge mustard seeds	In 7-months after-ripened seeds, expression was negatively affected by 20 mM KNO3 at 6 and 22 h of imbibition.	[81]
