Gene Details:

• Gene ID: Zm00001eb228530
• Gene Symbol: Sbe1 sbe1a spe1
• Gene Name: starch branching enzyme1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• 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.
• Sbe1 is maize kernel cDNA sequence is similar to starch branching enzyme I of bacteria, encodes a putative 64-amino acid plastid transit peptide.
