Ribosomal RNA as a Phylogenetic Tool in Plant Systematics

摘要: The traditional classification of plants into respective classes, orders, families, genera, and species has until recently been based on shared morphologic, cytologic, biochemical, ecologic traits. development techniques in molecular biology including those for hybridization, cloning, restriction endo-nuclease digestions, protein nucleic acid sequencing have provided many new tools the investigation phylogenetic relationships. At level, most fundamental comparison possible is primary nucleotide sequences homologous genes different populations or species.
