Gene Details

• Gene ID: Zm00001eb242610
• Gene Symbol: SBEIIb;Sbe2b;Sbe;ae1
• Gene Name: amylose extender1
• Species: Zea mays
• NCBI ID:
• Protein Sequence: Not Available
• Genome Version: Zm-B73-REFERENCE-NAM-5.0

Functions:

• Maize amylose is a type of high value-added starch used for medical, food, and chemical applications. Mutations in the starch branching enzyme (SBEIIb), with recessive ae (amylose extender) and dominant Ae1-5180 alleles, are the primary way to improve maize endosperm amylose content.
• A single mutation in the starch branching enzyme IIb isoform (SBEIIb), the amylose-extender gene (ae), resulted in > 50% of AC without greatly reducing the total quantity of starch.
• We found that Ae1-5180, as the dominant mutant allele of the SBEIIb gene, had distinct starch properties compared to the ae mutant.
