20.500.12556/RUL-180483 Biocontrol potential of Saccharomyces cerevisiae Meyen ex E.C. Hansen against Fusarium culmorum (Wm. G. Sm.) Sacc induced crown rot in wheat Potencial bionadzora s kvasovko Saccharomyces cerevisiae Meyen ex E.C. Hansena proti fuzarijski gnilobi pšenice, ki jo povzroča gliva Fusarium culmorum (Wm.G.Sm.) Sacc Fusarium crown rot (FCR), caused by Fusarium culmorum, (Wm.G.Sm.) Sacc is a destructive wheat disease that severely affects root and crown tissues, leading to plant weakening, reduced grain yield, and significant economic losses. This study investigates the biocontrol potential of Saccharomyces cerevisiae Meyen ex E.C. Hansen strains (Sc1, Sc2, Sc3) against F. culmorum (F19A isolate) through multiple antagonistic mechanisms. Direct confrontation assays revealed significant fungal growth inhibition, with Sc2 exhibiting the highest effect (57.53 %). Volatile compounds produced by S. cerevisiae further suppressed fungal expansion, with Sc1 demonstrating the strongest impact (49.6 %). Additionally, yeast treatments reduced conidial germination, with Sc3 achieving the highest inhibition rate (26.48 %). Beyond antifungal activity, S. cerevisiae strains enhanced wheat growth under pathogen stress by improving stem elongation, and root development. Enzymatic and biochemical analyses confirmed their ability to degrade fungal cell walls through chitinase and β-1,3-glucanase activity. Additionally, they exhibited plant growth-promoting traits such as phosphate solubilization, siderophore production, and indole-3-acetic acid (IAA) synthesis. This eco-friendly approach could serve as an alternative to chemical fungicides, reducing environmental risks while improving crop resilience and productivity. biocontrol Fusarium culmorum Fusariumcrown rot Saccharomyces cerevisiae wheat biotično varstvo rastlin Fusarium culmorum fuzarijska gniloba Saccharomyces cerevisiae pšenica true false true Angleški jezik Slovenski jezik Članek v reviji 2026-03-10 11:52:01 2026-03-10 11:52:08 2026-03-11 04:38:31 0000-00-00 00:00:00 2026 0 0 10 str. no. 1 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 1854-1941 10.14720/aas.2026.122.1.23300 271117315 SEGMANE+et+al.+(K).pdf SEGMANE+et+al.+(K).pdf 1 E8C909868B985E23D4747F5FE096F17B 3c0671a99798c197b398100f2b1e61c39aa6ab5838d9a7daf6ab4f7ddbd29ff8 0bc54f02-1c6f-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=229916 https://journals.uni-lj.si/aas/article/view/23300/20363 1 c324e2fd-1c6e-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=229915 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
