Is copper tolerance caused by metallothionein production? Murphy Copper soln. Control (water) Grown in high copper Control vs. X % of growth of control. Approach: Try to explain variation in copper tolerance among 10 wild populations of Arabidopsis. The Experiment: Do this for seedlings from all 10 populations.
