Tiina Sarkinen and colleagues Lynn Bohs, Dick Olmstead and Sandy Knapp have published a species-rich phylogenetic tree of the nightshade family - with more than 1000 species included, this is the biggest Solanaceae phylogeny yet! They used fossils and molecular methods to put dates on lineages in the family - many of the main lineages date from about 25 million years ago. The tree and these well-calibrated dates will allow us to look at evolution of key characters in the family in a robust framework - a real first.
One of the thirteen major clades of Solanum is the subject of a comprehensive monograph in the Open-Access journal PhytoKeys published in May 2013.
In a paper published in the open-access journal PLoS ONE, Sandy Knapp, Maria Vorontsova and Jaime Prohens update species circumscription for the relatives of the brinjal eggplant, Solanum melongena.
