agriculture | grain composition, amylose concentration, amylopectin unit-chain length distribution, and starch granule size distribution vary with the loss of functional granule-bound starch synthase GBSSI. Amylose concentration is more severely affected in genotypes with GBSSI missing from two genomes (double nulls) than from one genome (single nulls). Unit glucan chains (DP 6-8) of amylopectin are reduced with the complete loss of GBSSI as compared to wheat starch with a full complement of GBSSI. Alleles Wx-A and Wx-B have an additive effect toward short-chain phenotype of waxy amylopectin. Loss of Wx-D isoprotein alone significantly reduces the C-type starch granules. The absence of Wx-D in combination with Wx-A or Wx-B increases the B-type and C-type starch granules but decreases the volume of A-type starch granules. The rate of in vitro starch enzymatic hydrolysis is highest in completely waxy grain meal and purified starch | Triticum aestivum |
