Interpretive Summary:

Technical Abstract: Depending on life habits (such as tissue boring) insects can be exposed to plant pathogen resistance mechanisms through direct contact with the cuticle, which may inhibit efficacy of insect pathogens such as B. bassiana. Colonization of plant tissue by B. bassiana can also serve as an important secondary source of inoculum. Maize callus was transformed to overexpress several maize genes that promote antifungal activity against Fusarium plant pathogens, which included directly active proteins, proteins involved in biosynthesis of secondary metabolites, and regulatory genes that upregulate defensive genes. Growth of B. bassiana on maize callus transformed to express maize antifungal genes was reduced compared to control callus in several instances.
