A summary of progress in molecular phylogenetic studies of Solanaceae indicates that with over 50 published studies, more than 90% of genera and 37% of species have been sampled. Circumscription of Solanaceae now includes Nolanaceae, Goetzeaceae, Duckeodendron and Sclerophylax. Well-sampled groups include Capsicum, Lycium, Nicotiana, Nolana, and Petunia and the clades Anthocercideae, Goetzeoideae, and lochrominae. A major effort currently underway promises extensive sampling of Solatium. Groups thatremain poorly sampled include Cestrum, Brunfelsia, Jaltomata, Lydanthes and Juanulloeae.
