Genetic diversity of sotol (Dasylirion cedrosanum Trel.) at different elevations

Genetic analysis is important to identify genetic variability in organisms inhabiting a speci c region. In this study, a sotol population was characterized through ve elevational levels at one location in the Chihuahuan Desert in Mexico, using ampli ed fragment length polymorphisms (AFLP) markers.
