Petunia was genetically modified to express the A1 gene of Zea mays which is codes for dihydroflavonol-4-reductase. This reductase converts endogenously accumulated dihydrokaempferol to leukopelargonidin, resulting in the production of the pigment pelargonidin and therefore a salmon red flower colour.
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Notes regarding the genetic elements introduced or modified in this LMO
The A1 gene coding for the dihydroflavonol-4-reductase from Zea mays (CS-dfr-MAIZE) is expressed under the control of the 35S promoter and termination region of the Cauliflower Mosaic Virus (P-35S-CaMV and T-35S-CaMV).
Approximately 200 bp of the native genome were deleted at the insertion site. There is no evidence that this would lead to any functional changes.
