摘要：

An endogenous alpha-amylase inhibitor protein was identified in germinating grains of rye. This protein binds only with the alpha-AMY-1 group of alpha-amylase isozymes to modify their PAGE properties. IEF was employed to dissociate the enzyme and inhibitor proteins. Four alleles at the inhibitor locus found to be located on the long arm of chromosome 2R and designated Isa-1, were identified. The polymorphisms observed due to alpha-amylase-inhibitor interactions are explained in terms of allelic variation at alpha-Amy-1 and Isa-1.
