Abstract excerpt

Recently we reported on a plasma membrane tobacco protein (designated NtCBP4) that binds calmodulin. When overexpressed in transgenic plants, NtCBP4 confers Pb2+ hypersensitivity associated with enhanced accumulation of this toxic metal. To further investigate possible modulation of Pb2+ tolerance in plants, we prepared transgenic plants that express a truncated version of this protein (designated NtCBP4DeltaC)...
