| Alan Pepper received an A.B. from the University of California, Berkeley and a Ph.D from the University of California, Davis. After postdoctoral work at the Salk Institute for Biological Studies under the direction of Joanne Chory, he joined the Department of Biology at Texas A&M University in 1995. He was promoted to Associate Professor in 2002. |

| Research Interests
My laboratory uses genetic, molecular and genomic tools to study how terrestrial plants adapt, both in a short-term sense (phenotypic plasticity) and in a long-term sense (adaptive evolution), to the vast diversity of environments found on our planet. My laboratory is studying the molecular and physiological mechanisms of ‘downstream’ developmental responses to light using genetic and molecular tools available in the model plant Arabidopsis thaliana. In another project, we are using comparative genomics to investigate the genetic basis of the evolution-under-domestication of developmental processes in cultivated cottons (Gossypium spp.) and their wild relatives. Gossypium is in the Malvaceae family, and as such shares are recent common ancestor with Arabidopsis and other plants in the Brassicaceae family. We are also investigating the genetic mechanisms of plant adaptation to the stresses of extreme environments such as drought, low mineral nutrients (N,P,K) and heavy metals, in wild relatives of Arabidopsis, such as the rare endemic plant Caulanthus amplexicaulis (Brassicaceae), a wild relative of Arabidopsis. This work has led us to become more broadly interested in the conservation and ecological genetics of rare plants, particularly geoendemics. |
