Abstract
Plant cells contain cGMP and cAMP, signalling molecules that play crucial roles in animal, fungal and bacterial cells. Our results show that A. thaliana non-selective voltage independent ion channels (VICs) are deactivated by cAMP/cGMP, and that VICs form putative down stream targets in cyclic nucleotide based signalling pathways. Consistent with these observations and the notion that VICs may contribute significantly to plant Na+ entry, we find an increase in A. thaliana salt tolerance when exposed to membrane permeable cAMP/cGMP. We propose to characterise A. thaliana VICs in planta via a genetic and an electrophysiological approach, to characterise VIC genes in heterologous systems and to unravel the putative cyclic nucleotide based signalling pathway that is involved in plant salinity.
