Abstract

Cyclic nucleotide-gated ion channels have been identified in animals and plants. However, the physiological role of these ion channels in plant cellsand in nonreceptor cells of animals is still unknown. Here, we focused on one member of the large gene family of cyclic nucleotide-gated ion channelsfrom Arabidopsis thaliana (L. ) Heynh., AtCNGC2. The analysis of the transcriptional regulation revealed that expression of AtCNGC2 is low in etiolated seedlings but increases substantially during de etiolation. The use of promoter::GUS plants revealed that expression of AtCNGC2 in seedlings is highest in cotyledons after release of the developmental arrest by light. Expression of AtCNGC2 was also observed in later stages of plant development. Investigations using the promoter:: GUS plants demonstrated that AtCNGC2 is expressed in flowers during organ senescence and in the dehiscence zone of siliques. Furthermore, expression of AtCNGC2 was transiently induced during leaf and cell culture senescence. These results indicate a potential function for AtCNGC2 in the initiation of developmentally regulated cell death programs.
