Abstract
Data from morphological characters and sequence of chloroplast intergenic spacer region ndhF-rpl32 were analyzed for the same set of 18 species of Solanaceae and one outgroup Ipomoea cairica, a member of sister family Convolvulaceae. In the present study, ndhF-rpl32 intergenic spacer region was utilized to explore systematic relationships within Solanaceae. Sequence analysis revealed that the intergenic spacer ndhF-rpl32 was a hyper variable region in terms of nucleotide deletion compared to the other coding (rbcL, matK) and non-coding region (atpβ-rbcL) of the chloroplast genome. The result of separate parsimonious analysis revealed that the topology of both morphological and molecular phylogenetic trees were similar with respect to the division of subfamilies within Solanaceae but are in conflict with respect to the resolution of the tribal and intergeneric association within monophyletic subfamily Solanoideae. The sequence based parsimonious analysis results in few fully resolved clades within Solanoideae. Moreover, the Bayesian analysis provides the increased resolution within Solanoideae and for the rest of the tree.
