Funded Activity Summary

Drought and Salinity Tolerance in Metal Hyperaccumulating Plants: A Functional Role for the Metals? A few plant species can ?hyperaccumulate? metal ions to 100-1000 times the concentrations seen in ?normal? plants. Just why these plants have evolved such an extreme response to metalliferous soils remains an enigma. Many of the hyperaccumulators so far described are endemic to xeric environments, or saline soils prone to rapid drying. We hypothesize that the metals might act as osmotica, enhancing plant survival during water stress. This will be tested for Australian native and non-native hyperaccumulator plants. The study will clarify our understanding of the evolutionary significance of hyperaccumulation, and has important applications for extracting metals from contaminated soils.
