PHYTOCHELATIN SYNTHASE

摘要

The present invention relates to an isolated nucleic acid fragment encoding a phytochelatin synthase. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the phytochelatin synthase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the phytochelatin synthase in a transformed host cell.
