Abstract

Evidence for the role of the plasmalemma in metal tolerance of metal resistant ecotypes, cultivars and clones is presented. A range of tolerance mechanisms involving the plasmalemma are discussed including alterations to protein carrier and channel function and synthesis, efflux pumps and maintenance of plasmalemma integrity. Specific examples of such alterations from the literature on Al, As and Cu tolerance, where the plasmalemma has been shown to have a role in tolerance are considered. Tolerance by alterations to plasmalemma function in tolerant ecotypes may also rely on internal metal detoxification mechanisms constitutive in tolerant and non-tolerant plants.
