Abstract: Fusarium head blight (FHB) is a devastating fungal disease that poses a significant threat to wheat production, causing substantial yield losses. Understanding the molecular mechanisms of wheat resistance to FHB is crucial for developing effective disease management strategies. This study aimed to investigate the mechanisms of FHB resistance and the patterns of toxin accumulation in three wheat cultivars, Annong8455, Annong1589, and Sumai3, with different levels of resistance, ranging from low to high respecti… Show more

“…Xylan, a type of polysaccharide, is a major component and is primarily found in plant cell wall [ 8 ]. In the wheat cultivar Sumai3, the downregulation of genes involved in the xylan catabolic process is noted to contribute to its resistance against pathogens [ 9 ]. During an invasion by pathogenic fungi such as F. graminearum , these fungi secrete xylanases [ 10 ], which break down xylans, compromising the wheat cell wall integrity and facilitating further fungal invasion and spread [ 11 , 12 ].…”
