Relationships among deoxynivalenol, ergosterol and Fusarium exoantigens in Canadian hard and soft wheat

Summary: | Soluble extracellular components (exoantigens) from cultures of
Fusarium graminearum and
F. sporotrichioides were used to produce antisera from chickens for an indirect enzyme immunoassay. This immunoassay was used to estimate
Fusarium exoantigen levels in 40 samples of fusarium head blight-infected hard red spring wheat from Manitoba, and in 50 samples of infected soft white winter wheat from Ontario. These wheat samples were also assayed for deoxynivalenol (DON), the predominant
Fusarium mycotoxin, and for ergosterol, a metabolite reflecting fungal biomass. Using
F. sporotrichioides antisera, the linear correlations between exoantigen level and DON content for the hard and soft wheats had coefficients of 0.80 and 0.76, respectively. With the same antisera, linear correlations between exoantigen level and total ergosterol concentration for the hard and soft wheats had coefficients of 0.66 and 0.81, respectively. |
