1. A nucleic acid construct comprisinga first nucleic acid portion encoding a chalcone synthase (CHS), said first nucleic acid portion comprising a nucleotide sequence selected from the group consisting of:

  • (a1) Sequence ID No. 1; and

    (b1) nucleotide sequences encoding Sequence ID No. 2; and

    a second nucleic acid portion encoding anthocyanine reductase, said second nucleic acid portion comprising a nucleotide sequence selected from the group consisting of;

    (a2) Sequence ID No. 9; and

    (b2) nucleotide sequences encoding Sequence ID No. 10,said construct increasing the levels of both CHS and anthocyanine reductase when the construct is introduced into a plant cell.
