beta-Glucosidase (beta-D-glucoside glucohydrolase, E.C. 3.2.1.21, beta-Glu) isozyme variants were studied in a large number of inbred lines, crosses, and races of maize (Zea mays L.). The pattern of Mendelian inheritance demonstrated for beta-GLU variants indicated that they are under nuclear gene control. Twenty-two allelic forms at a single locus were identified in the materials studied by starch gel electrophoresis. Genetic data indicate that beta-GLU in maize is functionally a dimer. Variation of beta-GLU isozymes in 51 racial collections of maize from Mexico showed little correlation with morphological or geographical data. In 39 collections from Central America, variation patterns appeared to have some association with altitude.
对大量玉米（Zea mays L.）自交系、杂交种和品种中的β-葡萄糖苷酶（β-D-葡萄糖苷葡糖水解酶，E.C. 3.2.1.21，β-Glu）同工酶变体进行了研究。针对β-GLU变体所展示的孟德尔遗传模式表明，它们受核基因控制。通过淀粉凝胶电泳在研究材料中鉴定出了一个位点上的22种等位基因形式。遗传数据表明，玉米中的β-GLU在功能上是二聚体。来自墨西哥的51个玉米种族群体中β-GLU同工酶的变异与形态学或地理数据几乎没有相关性。在来自中美洲的39个群体中，变异模式似乎与海拔有一定关联。
