摘要
果蝇Drosophilanasuta亚群由14个处于不同物种分化阶段的种、亚种和分类元组成。这个亚群的物种有许多进化上的独特之处,使得它在物种分化研究方面倍受关注。然而,在形态学、生殖隔离、染色体和同工酶多态、线粒体DNARFLP、求偶歌特征以及线粒体和核基因序列分析等方面的研究都未能清楚地阐明这一亚群的系统进化关系。本文综合分析了关于这一亚群的进化遗传学的研究结果,并提出了有待进一步研究的一些问题。
Drosophila nasuta species subgroup, belonging to Drosophila immigrans
species group, consists of 14 closely related taxa in various levels of the speciation process.
This subgroup exhibits much evolutionary idiosyncrasies which attract great interest in the
study of speciation mechanism. However, extensive studies on morphometric, reproductive
isolation, chromosomal, allozyme variation, mtDNA RFLP, and courtship song characteristics
have failed to produce a coherent phylogenetic tree for this subgroup. This paper reviews the
available data on the phylogeny of this subgroup, and some ideas for future research are
proposed.
