Abstract

A process of increasing squalene and sterol accumulation in a transgenic plant by increasing the amount of a gene encoding a polypeptide having HMG-CoA reductase activity is disclosed. The amount is preferably increased by transforming plant cells with a recombinant DNA molecule comprising a vector operatively linked to an exogenous DNA segment that encodes a polypeptide having HMG-CoA reductase activity, and a promoter suitable for driving the expression of said polypeptide to form a transformed plant cell and regenerating a transgenic plant from that transformed cell. Also disclosed are a process of increasing pest resistance in a transgenic plant, transgenic plants and transgenic seeds capable of germinating into transgenic plants.
