Fusarium head blight (FHB) caused by Fusarium graminearum is a devastating disease on wheat not only because of severe yield loss, but also contamination of the grain with deadly mycotoxin. A recent study significantly advanced our understanding how wheat plants can be protected by resistance genes and provided tools in the fight against a major disease. A team led by Prof. Kong in Shandong Agricultural University successfully identified an important FHB resistance gene, Fhb7, and illuminated a mechanism by which this gene might have evolved in plants and a mechanism by which the resistance protein overcome the pathogen. This is an elegant study that not only opens new window to our understanding of plant-pathogen co-evolution, but also allows us to better utilize the rich gene resources of Thinopyrum elongatum for effective breeding of FHB resistance and other traits in wheat.
Key words： Fusarium head blight; wheat; disease resistance gene; DON; horizontal gene transfer
