Plant mitochondrial nucleic acid sequences as a tool for phylogenetic analysis.

摘要: To evaluate the potential of mitochondrial nucleic acid sequences as a phylogenetic tool, we have analyzed cytochrome oxidase subunit III (coxIII) coding in representatives major groups land plants. The tree derived from these confirms monophyletic origin plant mitochondria with general order and descent plants deduced by other molecular, physiological, morphological traits. strongly suggest close relationship between Bryophyta Lycopodiatae, whereas Psilophytatae cluster vascular In addition to high sequence similarity, both Hepaticophytina Lycopodiatae contain related intron coxIII gene that, our knowledge, is not found any species. slowly evolving are shown provide useful tool distant evolutionary relationships within this kingdom.
