To better understand the relationship between func- tions of cyclic nucleotide-gated channels (CNGCs) and plant physiology, we studied the effect of different ions on the growth of Arabidopsis cngc2 mutants. Here, we report the novel finding that cngc2 plants are specifically hypersensitive to calcium in their growth environments, leading to severe reductions in size and reproductive ability. CNGCs are important for sensory transduction in animals. The best characterized CNGCs are from the visual and olfactory systems. This class of channels does not discriminate well between alkaline metals
