On Wednesday, July 22, 2026, the Department of life sciences at the Faculty of science at the University of Mosul discussed the master’s thesis tagged ” efficiency of oil extracted from sunflower plant as a reducing agent for silver nanoparticles and their role as an antifungal agent”, presented by master’s student Hajar Samir Ismail al-Saegh from the Botany branch, in the presence of a number of faculty teachers, graduate students and researchers. The letter aimed to invest the oil extracted from the sunflower plant (Helianthus annuus L.) Resulting from the cultivation of plant tissues, as a reducing and stabilizing agent in the biosynthesis of silver nanoparticles in a safe and environmentally friendly way, and then characterizing their physical and chemical properties using UV-Visible Spectroscopy, FTIR, XRD and Cem techniques. The study also addressed the evaluation of the efficiency of bio-manufactured silver nanoparticles in inhibiting the growth of a number of plant pathogenic and toxin-producing fungi, studying their effect in reducing the production of those toxins, as well as evaluating changes in the level of gene expression of genes associated with their production using Real-time PCR technology. The results showed the successful biosynthesis of silver nanoparticles and their high inhibitory effectiveness against a number of pathogenic fungi, as well as their ability to reduce the production of mycotoxins and cause significant changes in the level of gene expression of the genes responsible for their synthesis. The study recommended the possibility of employing bio-manufactured silver nanoparticles using sunflower oil as a promising agent in the fight against pathogenic fungi and reducing mycotoxins, because of its bio-efficiency, as well as being an environmentally friendly option compared to some traditional methods, opening up prospects for future applications in the fields of Agriculture and biotechnology. The discussion Committee was chaired by Dr. Faten Nouri Abdul Hussein, with the membership of assistant professor Dr. Shaima Khalil Abdullah Najm, assistant professor Dr. Heba Hadi Taha Ahmed, and under the supervision and membership of Dr. Rana Tarek Yahya Qasem. Wishing our dear students continued success and success Government information and Communication Division Wednesday, July 22, 2026
