Evolution of Floral Symmetry in Gesneriaceae: Recent work on Antirrhinum and relatives have identified genes important in the control of floral symmetry, cycloidea and dichotoma. Homologs of cycloidea have been identified in Gesneriaceae known as GCYC. Although most Gesneriaceae have flowers with bilateral symmetry a few genera have full or partial radial symmetry (in the latter the corollas are radially symmetric or nearly radially symmetric, but stamen abortion results in 4 instead of 5 stamens). Investigations at the DNA sequence level of GCYC in Gesneriaceae with have not revealed any obvious mutations that may disrupt function of this gene in plants with radially symmetric flowers. Likewise rates of mutation at the DNA level and synonymous to nonsynonymous substitution rates are not significantly different for species with radial or bilateral symmetry. The control of symmetry for these plants must lie in other regulatory genes and investigations at the mRNA level are beginning.
Phylogenetics of tribe Episcieae (Gesneriaceae): The latest study represents and expansion of earlier studies on this tribe that used only a few genes and sampled only a few species for each genus. We sampled more widely from larger genera, sampled some of the more disparate morphological species in each genus and using more sequence data to more strongly support intergeneric relationships. As a result, four new generic names were published to reflect the monophyly in this clade.
Phylogenetics within Columnea (Gesneriaceae): Columnea is the largest genus within Neotropical Gesneriaceae and all previous attempts to resolve relationships within this genus have been poorly resolved or poorly supported. I have sampled many low copy nuclear genes in an attempt to identify a combination of sequences that will resolve and provide support for relationships within this genus. Currently, in collaborations with John L. Clark of the University of Alabama and Marisol Amaya-Marquez of Universidad Nacional de Colombia we are sampling nearly 40-50% of described species to test the current sectional classification within this clade. Results indicate that no previous subgeneric classification has reflected monophyletic groups and we are in the process of analyzing the data to resolve where new sectional delimitations can be made.
For more information on the Gesneriaceae, see the Tree of Life pages.
Phylogenetics of Piperaceae: I have been conducting research on the phylogenetics of Piperaceae in collaboration with Dr. Chris Davidson of the Idaho Botanical Research Foundation of Boise, Idaho. Our ultimate goal is to work on the phylogenetics of the family worldwide, but we are currently focusing our efforts on two clades that have been identified as a monophyletic group by both our studies and previous investigations. These are subgenera Enckea and Arctottonia. We are also sampling from several different genes, including low copy nuclear genes. The latter project is also in collaboration with Dr. Allan Bornstein of Southeast Missouri State University, Cape Girardeau, MO.

As director of the Snake River Plains Herbarium at Boise State University (SRP), I have seen the collection grow from a small teaching collection of ~6,000 specimens to a research and reference collection of ~50,000 specimens. The collection focuses primarily on plants of southwest Idaho, but we continue to add plants from throughout Idaho and surrounding states. The collection continues to expand through collections of faculty and students as well as an active exchange program. For information about exchange contact Dr. James Smith, email@example.com.
The first Idaho Botanical Foray was held in 2008, click here for a summary of that foray and updates on future forays and workshops.
