National Agricultural Genotyping Center

The Goss’s Wilt assay is currently under development is for the specific detection of the bacterial pathogen that causes Goss’s wilt and blight of corn. Clavibacter michiganensis subsp. nebraskensis (Cmn), the causal organism of Goss’s wilt, can infect a corn crop in any developmental stage, whether through wounds or transmitted directly through seed. Once the bacteria has colonized a crop, the surface-infested crop residue later becomes the main source of inoculum for future outbreaks of Goss’s wilt and leaf blight.

NAGC is optimizing a test for high throughput capabilities, that was very recently developed by a group from the University of MN (in press, McNally et. al., 2016), which utilizes a PCR-based assay to detect, identify and quantify the causal agent of Goss’s wilt (Cmn).  With the expansion of the assay into a high-throughput, quantitative test, NAGC be able to provide an accurate, sensitive and affordable method for producers and researchers to assess the potential for developing Goss’s wilt as a pre-screen of seed before purchase as well as detecting the organism in field samples to assess the bacterial lode in the field before planting to detecting the organism on symptomatic plant samples.


The National Agricultural Genotyping Center is supported through a public and private partnership of leading research and trade organizations including Los Alamos National Laboratory and National Corn Growers Association. The Los Alamos National Laboratory (LANL) will provide the technological and informatics expertises to maintain technological advancements and ensure diverse genotyping needs are met. In order to maintain close ties to the agriculture sector, the NAGC has partnered with the National Corn Growers Association (NCGA). NCGA represents 35,000 dues-paying corn farmers from 47 states and the interests of more than 300,000 growers who contribute through corn checkoff programs.
