MAMP and DAMP signaling contributes resistance to Fusarium graminearum in Arabidopsis.

Plants perceive externally produced microbe-associated molecular patterns (MAMPs) and endogenously produced danger-associated molecular patterns (DAMPs) to activate inducible immunity. While several inducible immune responses have been observed during Fusarium graminearum infection, the identity of the signaling pathways involved is only partly known. We screened 227 receptor kinase and innate immune response genes in Arabidopsis to identify nine genes with a role in F.

Two 14-3-3 proteins contribute to nitrogen sensing through the TOR and glutamine synthetase-dependent pathways in Fusarium graminearum.

Fusarium graminearum responds to environmental cues to modulate its growth and metabolism during wheat pathogenesis. Nitrogen limitation activates virulence-associated behaviours in F. graminearum including mycotoxin production and penetrative growth.
