The virus research team was originally formed in the 1960s in response to dual epidemics of maize chlorotic dwarf virus (MCDV) and maize dwarf mosaic virus (MDMV) that devastated Ohio's cornfields. The group originally consisted of a plant pathologist, a virologist, an entomologist, and a maize breeder. The ARS group collaborated with Ohio State University faculty in Entomology, Plant Pathology, and Crop Science to identify the two viruses and their vectors. Since then, the group has studied viruses that limit maize production across the U.S. and worldwide. The lab is an internationally recognized center of expertise in maize virus identification, characterization and epidemiology, and functions as an important early warning system for exotic viruses and vector-transmitted pathogens that threaten corn production in the U.S. Over the past 15 years, the group’s research has broadened to include the control of emerging virus diseases and insect pests that threaten soybean production.

Our Mission is to understand viruses and insect-transmitted pathogens that infect maize and soybean, their transmission and biology, and develop management strategies through host resistance and other technologies.

Current objectives

  1. Identify and characterize endemic and emergent viruses in corn and soybean, and develop sequence and detection resources.
  1. Develop genetic markers and germplasm associated with corn virus resistance genes, and transfer information for practical management solutions.
  1. Fine map, clone, and characterize virus resistance genes, facilitating the investigation of host-pathogen interactions.
