Phosphatidylcholine in wheat anthers is a susceptibility factor for Fusarium head blight

ABSTRACT: Fusarium head blight is a devastating wheat disease that initiates at flowering, with anthers as the preferred infection site. However, the anther-derived molecules driving this susceptibility remain elusive. Here, we identify anther-enriched phosphatidylcholine, particularly PC(18:2/18:2) and PC(16:0/18:2), as a key susceptibility factor that promotes Fusarium radial growth, while exogenously applied free linoleic acid specifically enhances conidial germination. Whereas endogenous linoleic acid is associated with defense rather than direct growth promotion.
