“…This ion can flow through the tonoplast by different types of ion channels (Allen and Sanders 1997; Pottosin et al 2003; Pottosin and Schönknecht 2007; Hedrich and Marten 2011; Hedrich 2012). Among them is the SV channel, whose activity has been recorded in the tonoplast of all higher plants tested (Pottosin et al 1997), but not in Charophyta algae (Laver and Walker 1991; Linz and Köhler 1994). Activity of these ion channels has also been recorded in the liverwort Conocephalum conicum phylogenetically related to Physcomitrella patens (Trebacz and Schönknecht 2000).…”

“…Yet patch-clamp recordings with isolated vacuoles from the green alga E . viridis resulted in whole vacuole currents reminiscent of SV currents, showing outward rectification, slow activation, Ca 2+ dependence, inhibition by acidification, and blockage by Zn 2+ [ 112 ]. There are no sequence data available for E .…”

“…Instantaneous currents across the vacuolar membrane of the unicellular green alga Eremosphaera viridis were interpreted to result from two different current components (Linz and K6hler, 1994): a voltage-independent component which was inhibited by increasing cytosolic Ca 2+ concentrations but not by high vacuolar Ca 2÷ concentrations, and an outward-rectifying component which was not affected by cytosolic Ca 2+. Both components are clearly different from the FV current.…”
