动物界、植物界和真菌界的分支顺序一直是一个有争议的问题。利用转换距离法和最大简约法，我们研究了这个问题，通过比较的几种大分子在生物体跨越所有三个王国的序列。该分析是基于大亚基和小亚基核糖体RNA，10 isoacceptor转移RNA家族，和6个高度保守的蛋白质。所有三组序列都支持同一个系统发育树：植物和动物是兄弟王国，比真菌分化得更晚。核糖体RNA和蛋白质数据集足够大，因此在这两种情况下推断的同源性在统计上是显著的。本报告似乎是第一个提供统计学上确凿的分子证据，为三国的繁衍。这一系统发生学的确定将有助于我们理解三个王国中任何两个王国所共有的各种分子、细胞和发育特征的进化。注意到大亚基rRNA序列在三个王国中以相似的速率进化，我们估计自动植物分裂以来的时间与真菌分歧以来的时间之比为0.90。
The branching order of the kingdoms Animalia, Plantae, and Fungi has been a controversial issue. Using the transformed distance method and the maximum parsimony method, we investigated this problem by comparing the sequences of several kinds of macromolecules in organisms spanning all three kingdoms. The analysis was based on the large-subunit and small-subunit ribosomal RNAs, 10 isoacceptor transfer RNA families, and six highly conserved proteins. All three sets of sequences support the same phylogenetic tree: plants and animals are sibling kingdoms that have diverged more recently than the fungi. The ribosomal RNA and protein data sets are large enough so that in both cases the inferred phylogeny is statistically significant. The present report appears to be the first to provide statistically conclusive molecular evidence for the phylogeny of the three kingdoms. The determination of this phylogeny will help us to understand the evolution of various molecular, cellular, and developmental characters shared by any two of the three kingdoms. Noting that the large-subunit rRNA sequences have evolved at similar rates in the three kingdoms, we estimated the ratio of the time since the animal-plant split to the time since the fungal divergence to be 0.90.
