摘要: 应用聚丙烯酰胺凝胶电泳对5种冬青科苦丁茶[即苦丁茶冬青(Ilex kudingcha C. J. Tseng),大叶冬青(I. latifalia Thunb.),枸骨(I. cornuta Lindl.),五棱苦丁茶(I. pentagona S. K. Chen,Y. X. Feng et C. F. Liang)以及霍山冬青(I. houshanensis Y. H. He)]共25份种质材料进行了酯酶同工酶的分析,计算了供试材料间的Jaccard相似性系数,并运用UPGMA法构建了聚类分析图。研究结果表明,25份种质材料共显示出18条谱带;在所有的谱带中,某些是所有供试材料共有的谱带,一些是同一物种所有材料的共有谱带,其余的谱带则显示不同材料间的遗传差异。可以根据酯酶同工酶的酶谱差异在种间水平上将分别属于5个不同物种的25份供试种质材料明显地分开;同一物种不同种质材料的酶谱既显示丰富的多态性,又显示出较明显的相似性。基于酯酶酶谱的25份供试材料间的相似系数变化范围在0.1333~1.0000之间。UPGMA聚类分析结果可以把分别属于冬青科5个不同物种的25份苦丁茶种质清楚地分开,按不同物种分别聚类,并表明它们之间的亲缘关系;同一物种内的不同种质材料其聚类关系基本上是按种质材料的地域来源进行,同时又与材料的形态特征有明显关系。酯酶同工酶分析结果可以作为冬青科苦丁茶种质材料种级水平分类鉴定的重要参考依据,并可以用于判断冬青科苦丁茶不同种质材料的起源地域、遗传差异以及它们之间的亲缘关系。

Abstract: The band differences of esterase isoenzymes of 25 Kudingcha germplasm materials in Aquifoliaceae, which involved 5 species, i.e. Ilex kudingcha C. J. Tseng, I. latifalia Thunb., I. cornuta Lindl., I. pentagona S. K. Chen, Y. X. Feng et C. F. Liang and I. houshanensis Y. H. He, were analysed via polyacrylamid gel electrophoresis. The similarity coefficients of the test materials, were calculated, and cluster dendrogoam for 25 germplasm materials was drawn by using UPGMA. The experimental results showed that there were 18 bands of esterase isoenzyme observed in all test materials. Of all bands, some of them were the common bands for the all test materials, some for all materials of the same species, and the others showed the genetic differences between different materials. Based on the band differences of the esterase isoenzymes, the 25 test germplasm materials from 5 species in Aquifoliaceae could be obviously distinguished on the species level. The bands of esterase isoenzyme of the test germplasm materials from the same species in Aquifoliaceae showed both abundant polymorphism and relatively obvious similarity. The similarity coefficient of the 25 test germplasm materials, based on the bands of esterase isoenzymes, ranged from 0.1333 to 1.0000. In the cluster analysis dendrogram, the 5 Kudingcha species in Aquifoliaceae could be clearly distinguished, which showed the relationships among the 5 species. The different germplasm materials from the same species were clustered according to their origins basically, which also showed the obvious relation relative to the morphological characteristics. The analysis results of the esterase isoenzyme could be considered as the significant reference bases for the classification of the germplasm materials of Kudingcha species in Aquifoliaceae on the species level, and could be used for determining the origination region, genetic difference, relationships of the germplasm materials of Kudingcha species in Aquifoliaceae.
