Research in the McHale lab focuses on the characterization and manipulation of natural variation in crop plants, primarily soybean and chile peppers. Our goals are to identify the genes conferring disease resistance, yield, and quality traits and, in soybean, examine how best to integrate these alleles for the development of improved varieties. To accomplish these goals, we use new technologies and a cross-disciplinary approach, which includes genetics and genomics, evolutionary studies, bioinformatics, and plant pathology.

    Graduate Student Bill Rolling passed his Ph.D. defense last week. Congratulations, Dr. Rolling!

  2. Congratulations Tu!

    Tu Huynh (PhD Student, Horticulture and Crop Science) was awarded an Ohio Soybean Council Grant for her project "Exploring Tools for Gene Characterization in Soybean Seeds". Her work aims to explore two molecular approaches, 1) virus induced gene silencing with Apple Latent Spherical Virus, and 2) gene silencing in soybean embryogenic tissue using CRISPR/Cas9 and particle bombardment, to characterize interesting genes in the seed system. 

  3. Stephanie Karhoff receives OARDC SEEDS grant

    Jul 17, 2018

    Stephanie Karhoff was awarded an OARDC SEEDS grant for her work “Identifying stages of Phytophthora sojae pathogenesis affected by a major quantitative resistance locus in soybean.” Her work will promote the development of new disease resistant cultivars and improve our understanding of the mechanisms underlying partial resistance. Congratulations, Stephanie!
