Dr. Triplett is a plant microbiologist and molecular geneticist. She studies the DNA sequences of plant-infecting bacteria to answer questions about their virulence mechanisms and phylogenetic diversity, and to develop diagnostic tools for disease detection.
RESEARCH INTERESTS In the past, her research has characterized the molecular interactions between Xanthomonas oryzae and rice, focusing on resistance to a few secreted proteins that act as toxins or transcriptional activators. She is now continuing that line of research on other plant pathogenic Xanthomonas species that infect a variety of crops.
