FgCWM1 modulates TaNDUFA9 to inhibit SA synthesis and reduce FHB resistance in wheat.

ABSTRACT:

Background

Fusarium head blight (FHB) significantly impacts wheat yield and quality. Understanding the intricate interaction mechanisms between Fusarium graminearum (the main pathogen of FHB) and wheat is crucial for developing effective strategies to manage and this disease. Our previous studies had shown that the absence of the cell wall mannoprotein FgCWM1, located at the outermost layer of the cell wall, led to a decrease in the pathogenicity of F. graminearum and induced the accumulation of salicylic acid (SA) in wheat. Hence, we propose that FgCWM1 may play a role in interacting between F. graminearum and wheat, as its physical location facilitates interaction effects.

Results

In this study, we have identified that the C-terminal region of NADH dehydrogenase [ubiquinon
