MOLECULAR PHYLOGENY OF CHLOROPLAST DNA OF SPECIES OF THE GENUS Nicotiana

摘要

Relationships among species of the genus Nicotiana were studied based on restriction analysis of amplified regions of chloroplast DNA. The phylogenetic tree constructed by the UPGMA procedure was in agreement with the classification based on morphologic and cytological investigations as well as the primary structure of the internal transcribed spacer of nuclear ribosomal DNA of these species.
