A study of α-amylase isozyme patterns from gibberellin-induced endosperms from more than 200 wheat genotypes has revealed allelic variation at five of the six α-Amy-1 and α-Amy-2 structural loci. These differences will find application as genetic markers and in varietal identification. The α-Amy-B1 locus on chromosome 6B was most variable and displayed eight distinct allelic forms. The nature of the allelic phenotypes, observations of segregating populations and the number of in vivo translation products of mRNAs from the α-Amy-1 and α-Amy-2 loci indicated that the individual loci are multigenic, each consisting of tightly linked subunits which produce several different isoforms.
对来自赤霉素诱导的超过 200 个小麦基因型胚乳的α-淀粉酶同工酶模式的研究揭示了六个α-Amy-1 和 α-Amy-2 结构基因座中的五个基因座的等位基因变异。这些差异将作为遗传标记并用于品种鉴定。染色体 6B 上的α-Amy-B1 基因座最具变异性，显示出八种不同的等位基因形式。等位基因表型的性质、分离群体的观察以及来自α-Amy-1 和α-Amy-2 基因座的 mRNAs 的体内翻译产物的数量表明，各个基因座是多基因的，每个基因座都由紧密连锁的亚基组成，这些亚基产生几种不同的同工型。
