Abstract Background In Arabidopsis thaliana the family of cyclic nucleotide-gated channels CNGCs is composed of 20 members. Previous studies indicate that plant CNGCs are involved in the control of growth processes and responses to abiotic and biotic stresses. According to their proposed function as cation entry pathways these channels contribute to cellular cation homeostasis including calcium and sodium as well as to stress-related signal transduction. Here we studied the expression patterns and regulation of CNGCI9 and CNGC20 which constitute one of the five CNGC subfamilies. Results GUS GFP and luciferase reporter assays were used to study the expression of CNGCI9 and CNGC20 genes from Arabidopsis thaliana in response to .
