SNARE protein FgVam7 controls growth, asexual and sexual development, and plant infection in Fusarium graminearum.

ABSTRACT: Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins play critical and conserved roles in membrane fusion and vesicle transport of eukaryotic cells. Previous studies have shown that various homologues of SNARE proteins are also important in the infection of host plants by pathogenic fungi. Here, we report the characterization of a SNARE homologue, FgVam7, from Fusarium graminearum that causes head blight in wheat and barley worldwide. Phylogenetic analysis and domain comparison reveal that FgVam7 is homologous to Vam7 proteins of Saccharomyces cerevisiae (ScVam7), Magnaporthe oryzae (MoVam7) and several additional fungi by containing a PhoX homology (PX) domain and a SNARE domain. We show that FgVam7 plays a regulatory role in cellular differentiation and
