Description:

Objective:

The objectives of this research project are to: (1) construct the transformation vectors with the already cloned metallohistin cDNA agNt84 under control by constitutive promoter CaMV35S; (2) transfer the genes into a woody plant, a Populus hybrid, and annual plants, Brassica napus and B. juncea, and confirm transformation by polymerase chain reaction (PCR) and Southern blot; (3) determine levels of RNA and protein expression in different tissues; (4) characterize the transgenic plants for their metal accumulation capacity and phytoremediation potential; and (5) determine the short- and long-term effects of the overexpression of metallohistin on growth and development of the transgenic plants.
