摘要利用聚合酶链反应（PCR）扩增产物，测定了头鸟科Caulocystis cephalornithos (Labillardiere) Areschoug （Cystoseiraceae）、banksii (Turner) Decaisne （hormosiracae）、马尾藻（R. Brown ex Turner） C. Agardh（马尾藻科）和Notheia anomala Harvey et Bailey （Notheiaceae）的核小亚基核糖体RNA基因（SSU）的部分核苷酸序列。这些分类群是目前被归入岩藻目的6个科中的3个，加上单型的Notheiaceae，它被不同地归入Chordariales， Fucales或Notheiales。我们的研究表明，SSU基因为评估岩藻科之间的关系提供了合适的分歧。部分SSU基因序列的系统发育分析表明，Notheiaceae与Fucales是一致的，尽管与其实际上的专性寄主——单型Hormosira banksii并不密切相关。关于……的位置，数据是模棱两可的。
Abstract Partial nucleotide sequences of the nuclear small-subunit ribosomal RNA genes (SSU), as inferred from polymerase chain reaction (PCR)-amplified products, have been determined for Caulocystis cephalornithos (Labillardiere) Areschoug (Cystoseiraceae), Hormosira banksii (Turner) Decaisne (Hormosiraceae), Sargassum vestitum (R. Brown ex Turner) C. Agardh (Sargassaceae) and Notheia anomala Harvey et Bailey (Notheiaceae). These taxa are referred to three of the six families currently placed in the order Fucales, plus the monotypic Notheiaceae, which has variously been placed in the Chordariales, the Fucales or the Notheiales. Our investigations indicate that the SSU gene provides suitable divergence for assessing relationships among the fucalean families. Phylogenetic analyses of the partial SSU gene sequences ally the Notheiaceae with the Fucales, although not closely with its virtually obligate host, Hormosira banksii of the monotypic Hormosiraceae. The data are equivocal as to the positioning of the...
