The research in our laboratory has as its objective the
analysis of the many modifications that occur to the structure of
plants as they become adapted to their habitats. We use two groups
of plants as the focus of our study: 1) cacti, and 2) parasitic
plants. Cacti have evolved to be well adapted to extremely xeric
conditions, and parasites are adapted to using the tissues of other
plants as a significant part of their habitat.
