This invention relates to isolated polynucleotides encoding a CYP51H. The invention also relates to the construction of recombinant DNA constructs comprising all or a portion of the isolated polynucleotide of the invention, in sense or antisense orientation, operably linked to at least one regulatory sequence.

Enzymes involved in triterpene synthesis

This invention relates to isolated polynucleotides encoding enzymes consisting of a carboxypeptidase-like protein, a methyltransferase and a glucosyltransferase, involved in the biosynthesis of &#x3b2;-amyrin-derived triterpenes in plants and seeds. The invention also relates to the construction of recombinant DNA constructs comprising all or a portion of the isolated polynucleotides of the invention, in sense or antisense orientation, operably linked to at least one regulatory sequence.

Promoters and genes involved in avenacin production in oats are cloned and characterized. Promoters for oxidosqualene cyclase and a cytochrome P450 are shown to be useful in root-specific expression of genes operatively linked to these promoters when introduced into plants. Sequences operably linked to the promoters are expressed in root epidermal cells.
