Fusarium sacchari Effector FsMEP1 Contributes to Virulence by Disturbing Localization of Thiamine Thiazole Synthase ScTHI2 from Sugarcane.

ABSTRACT: Fusarium sacchari is a significant pathogenic fungus that causes sugarcane Pokkah Boeng. Proteins secreted by pathogenic fungi can be delivered into hosts to suppress plant immunity and establish infection. However, there is still much to be discovered regarding F. sacchari's secreted effectors in overcoming plant immunity. In this paper, we characterize a novel effector called FsMEP1, which is essential for the virulence of F. sacchari. FsMEP1 contains a conserved zinc-binding motif sequence, HEXXH, and is highly expressed during host infection. Using the Agrobacterium tumefaciens-mediated transient expression system, it was confirmed that FsMEP1 could suppress Bcl-2-associated X protein (BAX)-triggered cell death, callose deposition, and ROS explosion in Ni
