用淀粉凝胶电泳分析了柑桔叶片提取液中己糖激酶(HK)、异柠檬酸脱氢酶(IDH)、亮氨酸氨肽酶(LAP)、苹果酸脱氢酶(MDH)和苹果酸酶(ME)的同工酶。前三种酶显示出单一的活性区域,暗示了它们各自为单基因所决定。带型表明了HK和LAP是单节显性,而IDH是双节显性。在几种栽培的柑桔及枳壳中发现了Hk和Idh的四个等位基因和Lap的三个等位基因。MDH的同工酶在三个凝胶区域出现,它们显然为四个基因所决定,其中 The contents of hexokinase (HK), isocitrate dehydrogenase (IDH), leucine aminopeptidase (LAP), malate dehydrogenase (MDH) and apple in the leaves of citrus were analyzed by starch gel electrophoresis Enzyme (ME) isoenzyme. The first three enzymes showed a single active region, suggesting that each of them is monogenic. Banding indicates that HK and LAP are monomorphic and that IDH is dynode dominant. Four alleles of Hk and Idh and three alleles of Lap were found in several cultivated citrus and trifoliate oranges. MDH isozymes appear in three gel regions, which are clearly determined by four genes, of which
