Wheat breeding for resistance to fhb combined with mycotoxin analysis and antioxidant pathways

Fusarium head blight (FHB), as a global problem, has a great economic impact on the cereal industry due to reduced seed quality and yield of wheat genotypes, but even most serious problem for human and animal consumption is the capability of the fungus to produce toxic secondary metabolites (mycotoxins). The purpose of this project is to find the wheat genotypes that have a certain level of resistance to FHB infections and will retain no or minimal concentrations of mycotoxins in grain and in processed products. Disease incidence and intensity will be measured in a couple of occasions to calculate the area under disease curve. DON, T-2 and HT-2 toxin, nivalenol, diacetoksiscirpenol, fuzarenon X and zearalenone will be analysed in wheat grain and malt. To obtain reliable information on the impact of artificial inoculation on quality of wheat genotype, it is necessary to study the composition and quantity of wheat proteins, with emphasis on gliadins and glutenins. Several antioxidant enzymes (guaiacol peroxidase, ascorbate peroxidase, superoxide dismutase, catalase) will be screened in a few occasions in order to find their potential correlation with plant resistance mechanisms to the pathogen attack. We will also check accumulation of free proline and malondialdehyde content, a final product of lipid peroxidation. This antioxidant pathways could help us to better understand DON accumulation in grain, because some investigations reported the involvement of external influences triggering DON production is further corroborated by research illustrating modulation of DON production by either abiotic or biotic factors, such as presence of other fungi. Wheat genotypes with efficient resistance to FHB can be used as germplasm in small grain breeding programmes of Agricultural Institute Osijek for future improvement and their use by growers can significantly reduce the risk of growing wheat and the losses associated with FHB.
