Genes have been introduced into maize plants that result
in red, blue or purple pigmented kernel tissue while
the hulls remain uncolored. This method can also be
used in other cereal grains for permanent coloration.
The invention would be highly useful as an indelible
warning "marker" for transgenic cereal grains
that are intended for use only as crop seeds, animal
feed or other restricted or special uses. It could also
provide for a variety of novel "naturally"
colored cereal grain products including: popping corn,
flour for preparation of bread or tortilla products,
snack foods, and grain-based beverages.
The invention has been reduced to practice in maize
and in arabidopsis. Transgene-derived pigments are localized
only in the endosperm tissues in high concentrations
and there are no apparent untoward effects on the plant.
