Gene Details

Functions:

  • Centered within the 5S QTL interval is another starch branching enzyme, starch branching enzyme 1 (sbe1), which also plays a role in the branching of amylopectin.
  • Kernels were genotyped for sbe1 alleles and assayed for relative amylose and amylopectin content. Kernels heterozygous or homozygous for the GEMS-0067 allele of sbe1 had a higher amylose/amylopectin ratio than kernels possessing the H99ae allele.
  • sbe1-Mu behaves as a simple recessive allele regardless of the other sbe1 allele. This implicates allelic variation of sbe1 as being responsible for the high endosperm amylose QTL.
