Grains that are high in soluble hemicellulose fiber, such as oat, provide numerous health benefits to consumers. These benefits include decreased risk of heart disease and lowered cholesterol. For this reason, information regarding genes that are involved in regulating starch and fiber synthesis in oat is highly valuable to breeders and cereal companies. However, because of the polyploid nature (allohexaploidy) and intrinsic complexity of the oat genome, given its propensity for chromosomal rearrangement, genetic data available for use in further research is limited, with many important regions still unsequenced. One such region is the gene coding for adenosine diphosphoglucose pyrophosphorylase (ADPG-PPase). ADPG-PPase is one of the major enzymes involved in oat hemicellulose and soluble fiber synthesis pathways. It acts as a catalyst for the first committed step in the synthesis of ADP glucose, which is then vital in the elongation of cellulose.
