My research team is interested in using genetics methodologies to develop superior high-yielding crop varieties with desirable phenotypes. The long-term goal is to contribute to better human livelihoods through improved food security. Our research utilizes interdisciplinary approaches like phenotyping, molecular biology, transcriptomics, and genome-wide association analysis to conduct experiments that aim to characterize the genetic basis of desirable phenotypes in sorghum and soybean. This comprehensive approach allows us to delve deep into the genetic underpinnings of these crops.

One of the traits studied in our lab is leaf angle, a key determinant of yield in sorghum (grain yield and biomass). Sorghum is a crop of economic importance that provides food, feed, and biofuel to humans and livestock. This drought-tolerant plant holds promise in the face of the climate change crisis that the world faces today. Next summer, our experiments will use imaging to compare sorghum collar tissue cell sizes across the plant canopy layers. We will also conduct genetics experiments to measure the expression of candidate genes by polymerase chain reaction-PCR (RT-PCR adn RT-qPCR) and correlate expression findings with cell sizes with genes involved in leaf angle determination.

Undergraduate research assistants will set up experiments in growth chambers, collect, and image collars, and sample collar tissue for gene expression analysis in the molecular lab. Students will also learn more about additional disciplines related to genetics and how to use publicly available data analysis tools to analyze biological datasets. This hands-on experience contributes to our research and fosters a sense of learning and growth. Research collaborations will continue with the Augustana biology department faculty and Iowa State University. Over time, new collaborations will be established within and outside of South Dakota.
