Phytate phosphorous is not bioavailable to monogastric animals. Thus, animal manure containing undigested phytate phosphorous is a source of environmental pollution. To improve the bioavailability of phosphorous in feed products and reduce environmental pollution, this maize was developed to express Aspergillus niger phytase A gene to reduce the levels of phytate phosphorous in the kernels of the maize. The enzyme liberates inorganic phosphate from phytate phosphorous.
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.

The modified maize contains one gene cassette for Aspergillus niger phytase A (phyA). The phyA coding sequence is under control of a maize legumin-1 promoter and terminator. The promoter is embryo-specific and expression of phyA is expect only in the seed tissues. A cysteine protease transit peptide was also included, likely to direct PHYA protein to the vacuole. The maize contains a single insertion with a partial reverse sequence of the histone H2B promoter from maize. The introduced genetic elements were integrated into chromosome 3 of the maize genome.
