摘要

为了阐明异倍体E.stevenii和E.boöphtona的祖先,我检测了来自澳大利亚的五个相关大马哈属物种的28个种群的11个同工酶位点和24个形态特征。根据遗传和形态学数据的分析,三个二倍体物种最近分化,但两个独立的多倍体物种估计分化时间相对较长。stevenii和boöphtona的大多数同工酶的固定杂合性强烈表明这两个物种是异倍体而不是自聚体。stevenii的同工酶谱表明,它是一种异多倍体,是由二倍体tannensis和未鉴定或已灭绝的四倍体物种之间的种间杂交进化而来。此外,同功酶谱有力地表明stevenii是bo霉的祖先之一。然而,E.boöphtona显示出大量固定等位基因,而在任何其他澳大利亚Eremophyton物种中都没有检测到。关于bo疫霉的起源,最有可能的假说是,它是由一个已灭绝的双倍体物种和六倍体stevenii之间的杂交和染色体加倍形成的。

The allopolyploid origin of Euphorbia stevenii and E. boöphthona (Euphorbiaceae)
To elucidate the ancestry of the allopolyploids E. stevenii and E. boöphthona, I examined eleven isozyme loci and 24 morphological characters from 28 populations representing five related Euphorbia species from Australia. According to an analysis of genetic and morphological data, three diploid species differentiated recently, but two independent polyploid species are estimated to have differentiated a relatively long time ago. Fixed heterozygosity for most isozymes in E. stevenii and E. boöphthona strongly suggests that these two species are allopolyploids rather than autopolyploids. The isozyme profiles of E. stevenii indicate that it is an allopolyploid that evolved from interspecific hybridization between the diploid E. tannensis and unidentified or extinct tetraploid species. In addition, isozyme patterns strongly suggest that E. stevenii was one of the ancestors of E. boöphthona. However, E. boöphthona showed a large number of fixed alleles that were not detected in any other Australian Eremophyton species. The most likely hypothesis for the origin of E. boöphthona is that it was formed by hybridization and chromosomal doubling between an extinct diploid species and the hexaploid E. stevenii.
