Prevalence and Risk Assessment of Multiple Mycotoxins in Durum Wheat from Fields Under Different Agricultural Practices in Tunisia.

Mycotoxin contamination in wheat, a staple food critical to human nutrition, poses significant public health concerns. This study investigated the natural occurrence of 17 mycotoxins in Tunisian durum wheat, assessed the influence of soil tillage practices on mycotoxin contamination, and performed an associated exposure risk assessment. A total of 167 wheat samples were randomly collected over two years (2021 and 2022) from fields managed under conventional tillage (CT) and no-tillage (NT) systems during both pre- and post-harvest periods.

Biological activities and determination of the mode of action of Tunisian and ethanolic extracts.

This study was designed to evaluate the antioxidant and antimicrobial activity of ethanolic extracts (EEs) of and . showed the highest values of phenolic compounds. Further, it was shown that EE of displayed the highest DPPH (IC50 = 8.

Detection of Maternal and Cytoplasmic Effects on Resistance to in Durum Wheat.

Septoria tritici blotch (STB) is a major disease problem of wheat worldwide. To optimize the introgression of resistance genes in elite genotypes throughout traditional or molecular breeding programs, a full understanding of the quantitative inheritance of resistance to , plant height (PH), and thousand kernel weight (TKW) is needed. In this study, maternal and cytoplasmic effects of resistance to STB were investigated using P1 (susceptible, high-yielding line) and P2 (resistant, low-yielding line) durum wheat lines and their F, RF, F, RF, BC, RBC, BC, and RBC progeny, assessed for resistance to STB during three growing seasons.
