Abstract
The present invention is directed to compositions and methods for altering the levels of seed proteins in cereal grain. The invention is directed to the alteration of seed protein levels in plant grain, resulting in grain with increased digestibility/nutrient availability, improved amino acid composition/nutritional value, increased response to feed processing, improved silage quality, and increased efficiency of wet milling.
Claims5
A genetically modified maize plant having improved grain quality as compared to the corresponding unmodified plant;
- wherein the improved grain quality is:
- increased energy availability, and a hard, vitreous endosperm;
- the improved grain quality being due to a stably decreased level of a 27 kD or 50 kD gamma-zein protein in the grain;
- wherein the genetic modification is selected from the group consisting of:
- co-suppression, and homology-dependent gene silencing, wherein the genetic modification targets 27 kD or 50 kD gamma-zein.
