In renewed taxonomic studies of the large neotropical genus                of sunflowers Viguiera, Dr. Edward Schilling of the University of               Tennessee will conduct field work in Mexico and Argentina to                    amass samples for intensive morphological and molecular analyses                of characters useful in delimiting species and in assessing                     relationships with other sunflower genera.  Preliminary analysis                of mutations in chloroplast DNA demonstrates that restriction-                  site mapping will be especially informative.  The phylogenetic                  framework provided by the molecular data will then permit                       rigorous study of morphological and chromosomal changes in the                  several Mexican and Central-South American lineages of the group.               Also, Dr. Schilling will be able to test whether a single                       migration from ancestral Mexican stock or multiple migrations                   best explains the diversity of related species in Andean South                  America.
