Systematic And Evolutionary Studies in Lupinus (Fabaceae) from argentina

Dra. Alicia López (Postdoctoral Fellow at CONICET, developing activities at the Instituto de Botánica Darwinion (SI herbarium), San Isidro, Buenos Aires, Argentina.

The aim of the project is to perform the analysis of the diversity and genetic differentiation in Lupinus populations, to infer primarily, the processes that determined the diversification of the taxa, and in a general context, to interpret the evolutionary changes of the plants in response to climatic and geomorphological changes.

Lupinus comprises c. 280 annual and perennial species. The majority of species occur in the New World, with two main centers of species diversity in western North America (c. 100 species) and the Andes (c. 85 species). Lupinus of interest grows in the Argentinean Patagonia. Most of these Argentinean species have not been studied until the present and their distribution is poorly known.

The grant contributed to perform a collection trip that allowed the examination of the species in the field and to collected herbarium material (now deposited at SI), seeds (stored to be used to obtain roots for cytological studies), and leaves that were dried out in silica gel and stored for molecular studies. Now I am back into the lab I will determinate the material, and then I’ll perform the cytogenetic and molecular studies in order to accomplish the proposed goals of this project.
