Abstract

The nucleotide sequences of 5S rRNAs from sponge Halichondria japonica and tunicate Halocynthia roretzi were determined by chemical and enzymatic gel methods. Their phylogenetic positions among metazoans were derived from the 5S rRNA sequences by a computer analysis based on the maximum parsimony principle. It was suggested that the sponge is closely related to several invertebrates and the tunicate has affinity to vertebrates rather than invertebrates.

摘要

采用化学和酶促凝胶法测定了日本海绵(Halichondria japonica)和海鞘(Halocynthia roretzi)的5S rRNA核苷酸序列。基于最大简约原则,通过计算机分析从5S rRNA序列推导它们在后生动物中的系统发育位置。结果表明,该海绵与几种无脊椎动物关系密切,而海鞘与脊椎动物而非无脊椎动物具有亲缘关系。
