Patent ID: 8647875

Claim:
A method of producing a plant with altered levels of CYP51H comprising: a) transforming a plant cell with a first recombinant DNA construct comprising an isolated polynucleotide comprising: i) a nucleotide sequence encoding a Cyp51H enzyme having an amino acid sequence that is at least 95% identical, based on the Clustal V method of alignment with pairwise alignment default parameters of KTUPLE=1, GAP PENALTY=3, WINDOW=5 and DIAGONALS SAVED=5, when compared to SEQ ID NO:14; or ii) a nucleotide sequence comprising the full complement of (i); b) growing the transformed plant cell from step (a) under conditions that promote the regeneration of a whole plant from the transformed cell; wherein the plant regenerated from the transformed cell produces an amount of CYP51H that is greater than the amount of the CYP51H that is produced in a plant that is regenerated from a plant cell of the same species as the plant of step (a) that is not transformed with said first recombinant DNA construct; and optionally c) transforming the plant cell of step (a) with a second recombinant DNA construct comprising a nucleic acid sequence encoding a polypeptide that regulates expression of at least one enzyme of the triterpene pathway; and d) growing the transformed plant cell from step (c) under conditions that promote the regeneration of a whole plant from the transformed cell; wherein the plant regenerated from the transformed cell produces an amount of CYP51H that is greater than the amount of the CYP51H that is produced in a plant that is regenerated from a plant cell of the same species as the plant of step (c) that is not transformed with said first recombinant DNA construct and said enzyme of the triterpene pathway of said second recombinant DNA construct.
