My sincere apologies to many colleagues whose research was notcited due to space constraints. Many special thanks to ProfessorI. Pottosin (University of Colima) for valuable references onlocalization of K⁺ transporters within cell organelles. I wouldlike also to acknowledge Drs I. Newman, O. Babourina and L.Shabala for the critical reading of this manuscript and helpfulsuggestions, and my son Stas for technical assistance. The financialsupport from ARC and AusIndustry is greatly acknowledged.
