Out of America to Asia or Africa? Relationships among Old World Lycium (Solanaceae).
Tribe Lycieae originated in the Americas, with subsequent dispersal to the Old World. Although much is known about relationships within the tribe and among the largest genus Lycium, relationships among the Old World species are equivocal. In particular, it is not yet clear how the East Asian and Mediterranean species are related to southern African species. Knowledge of such relationships has implications in terms of understanding dispersal patterns, specifically whether Lycium went first to Africa or Asia from the Americas. Using data from four plastid spacer regions and two nuclear regions, the granule bound starch synthase gene (GBSSI) and a conserved ortholog set II (COSII) marker, we explore relationships among Chinese Lycium, as well as their relationships to other Old World Lycium species. In addition to providing a better understanding of dispersal patterns, these evolutionary relationships provide for a much needed re-evaluation of species delimitations within Chinese Lycium, including the cultivated Goji berry (Lycium barbarum).
