Claim Text:
1. A method of modulating poly unsaturated fatty acid biosynthesis in an algal cell, said method comprising: enhancing or suppressing expression of an elongase 6 comprising the amino acid sequence of SEQ ID NO: 14 in said algal cell, wherein said enhancing expression comprises replacement of an endogenous promoter with a strong promoter in front of a gene encoding said elongase 6, wherein said suppressing expression is selected from the group consisting of replacement of an endogenous promoter with a weak promoter in front of a gene encoding said elongase 6, an insertion in a gene encoding said elongase 6 comprising the amino acid sequence of SEQ ID NO: 14, and a deletion or a substitution of a portion or a full length of said gene encoding elongase 6 comprising the amino acid sequence of SEQ ID NO: 14, wherein said strong promoter is stronger than said endogenous promoter and said weak promoter is weaker than said endogenous promoter; thereby modulating poly unsaturated fatty acid biosynthesis in said algal cell.
