86 words
A method of producing a hydroxylated fatty acyl compound in a seed of a plant comprising: (a) providing a fatty acyl compound in said seed of said plant, wherein said fatty acyl compound is a substrate for oleate-12 hydroxylase; and (b) expressing oleate-12 hydroxylase from an integrated DNA construct in said seed of said plant to hydroxylate said fatty acyl compound, wherein said DNA construct encodes amino acid sequence SEQ ID NO:40, whereby said hydroxylated fatty acyl compound is produced in said seed of said plant.
Claim 9
Independent Claim
86 words
A method of producing a hydroxylated fatty acyl compound in a seed of a plant comprising: (a) providing a fatty acyl compound in said seed of said plant, wherein said fatty acyl compound is a substrate for oleate-12 hydroxylase; and (b) expressing oleate-12 hydroxylase from an integrated DNA construct in said seed of said plant to hydroxylate said fatty acyl compound, wherein said DNA construct encodes amino acid sequence SEQ ID NO:40, whereby said hydroxylated fatty acyl compound is produced in said seed of said plant.
