Plant breeding, genetics & genomics; disease resistance; grain quality; soybean, lettuce, and chile pepper
Research in the McHale lab focuses on the characterization and manipulation of natural variation occurring in crop plants, primarily soybean and chile peppers. Specifically, the research program is involved in the identification of genes conferring disease resistance, yield, and quality traits and, in soybean, examining how best to integrate these alleles for the development of improved varieties. To accomplish this, new technologies and a cross-disciplinary approach are exploited, which includes genetics and genomics, evolution, bioinformatics, and plant pathology. Particular interests are the study of breeding methodologies, disease resistance, domestication and agronomic traits for both the development of improved cultivars and evolutionary and molecular plant-pest interactions studies.
