The strategy of Fusarium graminearum against SA. SA can be toxic to the cell membrane and cell wall of F. graminearum and affect chitin production. In response, F. graminearum activated the transcription of a large number of genes. Specifically: FgCWM1 generates cell wall mannoprotein (CWM), which resides SA at the outermost layer of F. graminearum's cell wall. FgCHS8 located on the cell membrane is chitin synthase and is inhibited by SA. FgABCC9 and FgMFS1, as transport proteins that function on the cell membrane, transport the intracellular SA of F. graminearum to the extracellular space, among which the subcellular localization of FgMFS1 is transferred from the vacuole to the cell membrane. FgLAI12 also needs to be transferred from the vacuole to the cell membrane to resist the toxicity of wheat linoleic acid, and SA prevents its translocation. SA carboxylase FgNahG degrades SA near the vacuole.
