Sequencing the Secrets of Solanum.

Solanum (Solanaceae) is one of the 10 largest genera of flowering plants, with approximately 1400 species including the tomato (S. lycopersicum), eggplant (S. melongena), and potato (S. tuberosum). The size, diversity, and economic importance of Solanum make it ideal for biological study ranging from sequencing the genome of the tomato and potato to recent DNA sequencing identifying the groups within the genus. One of largest major monophyletic groups identified within Solanum is the Leptostemonum clade, considered the “spiny solanums”, with approximately 350-450 species. Within the spiny solanums, 14 major clades have been established, but further studies of individual clades are needed to clarify the taxonomy and give evolutionary insight into this “giant genus”. One of the 14 clades of Leptostemonum is the Torva clade. This clade has low phylogenetic resolution and there is very little statistical support for relationships within the clade. In order to clarify the evolutionary relationships within the Torva clade, we compared eight gene regions for 35 Solanum specimens. DNA sequences were amplified using PCR, sequenced, and aligned. Phylogenetic analysis and preliminary results for the Torva clade are presented which clarify the relationships between species and strengthens the phylogeny of Solanum.
