Title:
分枝酵素の活性を改変した小麦、ならびにそれから得たデンプンおよびデンプン含有品
Document Type and Number:
Japanese Patent JP4923171
Kind Code:
B2
Abstract:
Wheat having a reduced level of SBEIIa activity, that may have a relative high amylose content. Wheat having a mutant SBEIIa gene in the A genome. The wheat might additionally have reduced levels of SBEIIb activity. The wheat grain of this invention can be of a non-shrunken phenotype despite a lesion in the amylopectin synthesis pathway, and may also have a high relative amylose content.
