Tissue specificity is a pathogen’s preference for infecting one section of tissue (i.e., root, stem, or head) over another. 1 Having a better understanding of a pathogen’s ability to cause disease on specific tissues could contribute to new mechanisms of disease control. This will allow growers to make the best decision on effective pathogen management. In 2022, Fusarium isolates were collected from wheat heads and roots across Illinois. These isolates were used in a pathogen aggressiveness assay on wheat roots, in an in vitro growth rate experiment , and in the development of a spore quantification protocol. The phenotypic traits measured in these experiments will be used to determine if Fusarium isolates show tissue specificity.
Hypothesis: Fusarium strains isolated from diverse tissues have different pathogenesis and fitness components.
