Abstract

The aim of this project is to enable for the first time identification of the physiologically relevant permeation of nonselective cation channels, thus enabling attribution of function (e.g. Ca2+ channel, Na+ channel) to several gene products. This will be done by using a vibrating multi-barrelled ion-selective electrode system to measure, in complex solutions, local depletion of Na+, K+ and Ca2+ ions near the plasma membrane of patch clamped Arabidopsis protoplasts transiently overexpressing a range of Arabidopsis ion channels (co-expressed with gfp to enable identification of successfully transformed protoplasts). Channel-GFP fusions will be used to identify membrane localisation of gene products using confocal microscopy.
