Chloroplast and mitochondrial DNA from nine species or taxons of coffee-trees were compared as to their phylogenetic relationship by restriction endonuclease fragment analysis. Three types of chloroplast DNA (cp DNA) were detected indicating relationships as follows: (i) C. arabica, C. eugenioides; (ii) C. canephora, C. congensis, "nana" taxon; (iii) C. liberica. The mitochondrial DNA (mt DNA) separated into five types: (i) C. arabica, C. eugenioides, C. congensis; (ii) C. canephora, "nana" taxon; (iii) C. excelsa; (iv) C. liberica; (v) Paracoffea ebracteolata. The divergence in organelle DNAs agrees with the phylogenetic relationship deduced by conventional methods and is presented in some detail. Restriction patterns of the cp and mt DNAs isolated from a clone of C. arabusta have been compared to those of the parents and were found to be inherited from the mother. Cp and mt DNA analyses in the genus Coffea support the hypothesis that C. canephora diverged from C. congensis, whereafter the latter species differentiated into C. eugenioides and C. arabica.
利用限制内切酶片段分析比较了来自 9 种咖啡树种或分类群的叶绿体和线粒体 DNA，以探讨它们之间的系统发育关系。检测到 3 种类型的叶绿体 DNA（cpDNA），表明以下关系：（i）C. arabica、C. eugenioides；（ii）C. canephora、C. congensis、“nana”分类群；（iii）C. liberica。线粒体 DNA（mtDNA）分为 5 种类型：（i）C. arabica、C. eugenioides、C. congensis；（ii）C. canephora、“nana”分类群；（iii）C. excelsa；（iv）C. liberica；（v）Paracoffea ebracteolata。细胞器 DNA 的差异与传统方法推断的系统发育关系一致，并作了一些详细的介绍。对 C. arabusta 克隆分离的 cp 和 mt DNA 的限制图谱与亲本进行了比较，发现它们是从母本遗传下来的。咖啡属的 cp 和 mt DNA 分析支持以下假说，即 C. canephora 起源于 C. congensis，此后后者分化为 C. eugenioides 和 C. arabica。
