OverviewAI-generated summary
Larry C. Purcell's research centers on plant genetics and physiology, with a particular focus on soybean (Glycine max). His work investigates the genetic underpinnings of traits such as drought tolerance and yield potential, employing techniques like genome-wide association studies (GWAS) and quantitative trait locus (QTL) mapping. He has explored the relationship between symbiotic nitrogen fixation and a plant's response to drought conditions, examining how factors like ureide levels and amino acid concentrations are affected. Purcell has also studied methods for quantifying plant characteristics, such as turfgrass and soybean canopy coverage, using digital image analysis. His research has contributed to understanding crop transformation and strategies for increasing yield potential. Purcell holds a significant publication record, with 194 total publications and over 8,700 citations, reflected in his h-index of 54 and designation as a highly cited researcher. He has collaborated with several researchers at the University of Arkansas at Fayetteville, including Avjinder S. Kaler, Siva K. Chamarthi, C. Andy King, and Jeremy Ross.
