Insights into the History of Oaxacan Chile Pepper Landraces from Genotyping-by-Sequencing
University of Georgia, Ph.D. student
Selected from the 2016 Fall Plant Center Retreat poster competition.
Nathan Taitano is a Ph.D. student in the van der Knaap lab, studying population genomics and historic selection for fruit size, shape, and drying traits in chile pepper (Capsicum spp.) landraces from Oaxaca, Mexico. Nathan received a Bachelor of Arts degree in Biology from The College of Wooster, Ohio, 2014. He began his doctoral studies at Ohio State University (OSU) in the van der Knaap lab prior to his arrival at UGA in the fall of 2015. His current work is on conducting genome-wide scans for admixture and selection in a collection of Oaxacan chile pepper landraces taken from near the center of C. annuum diversity using SNPs generated from Genotyping-by-Sequencing, finding QTLs for fruit traits mentioned above in biparental populations derived from collection landraces varying for said traits, and ultimately combining QTL-mapping and genome-scan information to find genetic loci responsible for the morphological divergence of chile pepper landraces selected for specific use types.
