Abstract
The efficacy of using an electrophoretic mutant to mark chromosome aberrations was demonstrated for an interchange in maize. Using a closely-linked esterase gene (E(4)), plants homozygous and heterozygous for this interchange and plants homozygous for the normal chromosomes were detectable in the seedling stage via an electrophoretic assay; the error was only 0.3%.
摘要
利用电泳突变体标记染色体畸变的功效在玉米的易位中得到了证明。利用紧密连锁的酯酶基因 (E(4))，通过电泳分析可以在幼苗阶段检测到这种易位的纯合子和杂合子以及正常染色体的纯合子植物；误差仅为 0.3%。
