GrainGenes Gene Set Report: SbeII

[Submit comment/correction]

Gene Set	SbeII
Reference	Schonhofen A et al. (2016) Registration of common wheat germplasm with mutations in SBEII genes conferring increased grain amylose and resistant starch content. Journal of Plant Registrations 10:200-205. [ Show all 6 ]
Gene Class	Amylose (resistant starch) content
Gene	SbeIIa-A (Triticum) [ Show all 6 ]
Comment	starch branching enzyme II Suppression of SBEIIb expression alone had no effect on amylose contents, however, suppression of both SBEIIa and SBEIIb expression resulted in wheat starch containing >70% amylose (Regina, et al.). Combined loss-of-function mutations in SbeIIa-A, SbeIIa-B, SbeIIb-A, and SbeIIb-B (PI 670160) increased amylose content by 66% and resistant starch by 753% relative to the control in tetraploid wheat cv. Kronos (Hazard, et al.). Combination of these four mutations with mutations of SbeIIa-D in hexaploid wheat (PI 670160) increased amylose content by 63% and resistant starch by 1,057% in field experiments relative to the control (Schonhofen, et al.)
