Effect of Increasing Arsenate Exposure on Root Growth of Holcus Lanatus

Arsenate is an analog of phosphate, competing for the same uptake carriers in the root plasmalemma. Arsenate
tolerance has been identified in a number of plant species. Tolerance in grasses results via suppression of the
high-affinity phosphate/arsenate uptake system.
