Abstract
Corn (Zea mays L.) ribonuclease II of the root microsomal fraction was isolated from 11 inbreds and seven hybrids. Polyacrylamide gel electrophoresis revealed a total of five bands of activity among corn lines tested. Most inbreds had only one isoenzyme, but three had two isoenzymes. The hybrids tested contained all of the isoenzymes found in the parental inbreds.
摘要
从11个自交系和7个杂交种中分离出玉米（Zea mays L.）根微粒体部分的核糖核酸酶II。聚丙烯酰胺凝胶电泳显示，在所测试的玉米品系中共有五条活性带。大多数自交系只有一种同工酶，但有三个自交系有两种同工酶。所测试的杂交种包含了在亲本自交系中发现的所有同工酶。
