Journal ArticleA data set derived from gene sequences of ndhF is used to deduce phylogenetic relationships among the subgenera of Solanum, among related genera of the tribe Solaneae, and within selected Solanum clades. Complete ndhF sequences were obtained for 12 species o f Solanum, representing five of the seven subgenera. ndhF sequences also were obtained from species of Capsicum, Cyphomandra, Datura, jaltomata, Lycopersicon, Nicotiana, and Physalis. Results of a parsimony analysis of these data indicate that the Solanum species form a monophyletic clade with Capsicum rather weakly supported as the sister group
