Abstract

Restriction endonuclease patterns of mitochondrial DNA from seven species of the genus Aspergillus (A. nidulans, A. wentii, A. awamori, A. niger, A. oryzae, A. tamarii and A. echinulatus) have been compared in order to test the phylogenetic relationships between these species. The fraction of restriction fragments common between all pairs of species from this set ranged from 0 to 1. The use of this approach for the taxonomy of the genus Aspergillus is discussed. The postulated phylogenetic relationships differ significantly in two cases from the classification of the genus presented by Raper & Fennell (1965).

摘要

为了检验曲霉属七种曲霉（构巢曲霉、米曲霉、泡盛曲霉、黑曲霉、米曲霉、酱油曲霉和棘孢曲霉）之间的系统发育关系，对其线粒体DNA的限制性内切酶图谱进行了比较。该组中所有物种对之间共有的限制性片段比例在0到1之间。讨论了这种方法在曲霉属分类学中的应用。在两种情况下，推测的系统发育关系与Raper和Fennell（1965年）提出的曲霉属分类有显著差异。
