Disclosed are constructs comprising sequences encoding
3-hydroxy-3methylglutaryl-Coenzyme A reductase and at least one other
sterol synthesis pathway enzyme. Also disclosed are methods for using such
constructs to alter sterol production and content in cells, plants, seeds
and storage organs of plants. Also provided are oils and compositions
containing altered sterol levels produced by use of the disclosed
constructs. Novel nucleotide sequences useful in the alteration of sterol
production are also provided. Also provided are cells, plants, seeds and
storage organs of plants comprising sequences encoding
3-hydroxy-3methylglutaryl-Coenzyme A reductase, at least one other sterol
synthesis pathway enzyme and at least one tocopherol synthesis enzyme.
