OverviewAI-generated summary
Margaret Worthington's research focuses on plant genetics and breeding, with a particular emphasis on fruit crops and forage grasses. Her work involves utilizing genomic tools and advanced analytical methods to understand genetic diversity and identify key loci associated with desirable traits. She has investigated fruit quality hotspots in peach and identified loci controlling postharvest quality in blackberry, contributing to advancements in plant breeding for improved agricultural outcomes. Worthington also studies plant responses to environmental stressors, examining gene expression in hybrid Brachiaria genotypes under water stress. Her research extends to the development of genetic tools, such as multiplexed SNP arrays for selective breeding and species conservation. She has a publication record of 101 articles, with an h-index of 19 and over 1,400 citations, and collaborates with researchers at the University of Arkansas at Fayetteville.
