MAJOR CLADES IN SOLANUM BASED ON ndhF SEQUENCE DATA
نویسندگان
چکیده
Analysis of sequence data from the chloroplast gene ndhF identifies at least 12 major well-supported clades within the genus Solanum. These are briefly described, given informal clade names, and compared with the groups recognized by previous Solanum workers. Non-molecular synapomorphies are proposed for many of the clades. Continued use of informal taxonomic designations is advocated for new infrageneric groups within Solanum.

Solanum Phylogeny Inferred from Chloroplast Dna Sequence Data
A 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 of Solanum, representing five of the seven subgenera. ndhF sequences also were obtained from species of Capsicum, Cyphomandra, Datura, Jalto...
متن کاملA Three-Gene Phylogeny of the Genus Solanum (Solanaceae)
Solanum, with approximately 1,500 species, is the largest genus in the Solanaceae and includes economically important species such as the tomato, potato, and eggplant. In part due to its large size and tropical center of diversity, resolving evolutionary relationships across Solanum as a whole has been challenging. In order to identify major clades within Solanum and to gain insight into phylog...
متن کاملndhF sequence evolution and the major clades in the sunflower family.
An extensive sequence comparison of the chloroplast ndhF gene from all major clades of the largest flowering plant family (Asteraceae) shows that this gene provides approximately 3 times more phylogenetic information than rbcL. This is because it is substantially longer and evolves twice as fast. The 5' region (1380 bp) of ndhF is very different from the 3' region (855 bp) and is similar to rbc...

Solanum is one of the largest angiosperm genera, with approximately 1,500 species distributed worldwide. The genus includes important economic plants such as the tomato, potato, and eggplant, as well as a number of lesser-known cultivated species such as the pepino (S. muricatum Aiton), naranjilla (S. quitoense Lam.), cocona (S. sessiliflorum Dunal), and tree tomato (S. betaceum Cav.). Although...

The genus Ranunculus L., with a worldwide distribution, is the largest member of the Ranunculaceae. Here, nuclear ribosomal internal transcribed spacer (ITS) sequence data and chloroplast trnLF sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (Group Praemorsa, Group Rhizomatosa, Group Grumosa and Group non-Grumosa) species of Ranunculus...
