超氧物歧化酶同工酶在杂交大豆中的表现

THE ISOENZYMES OF SOD IN SOYBEAN HYBRIDS

摘要:

17个杂交组合41个品种大豆SOD同工酶酶谱,分全酶谱类型和残酶谱类型。全酶谱和全酶谱类型杂交,后代多数为全酶谱,少数为残酶谱;全酶谱和残酶谱杂交,后代出现全酶谱和残酶谱。大豆SOD同工酶谱的全酶谱类型和残酶谱类型可能受同一位点的一对等位基因控制。

Abstract:

SOD isoemzymes of 17 crosses of soybeans were analyzed by polyacrylamide gel electrophoresis. The SOD isoenzymes in soybeans could be divided into complete and incomplete enzyme pattern types. It was shown that both the complete and the incomplete patterns of enzymes appaeared in the offsprings from soybean crosses of complete type with incomplete type. But when crossing the soybeans of complete pattern type each other, most of the offsprings showed a complete pattern and a few was the incompelet one. The two types of SOD zymograms may be conditioned by a pair of genes at the same locus.
