Transcriptomic profiling of the effect of peroxidase on Wild-type Fusarium

Fungal hyphal chemotropism has been shown to be a major contributor in host-pathogen interactions. Previous studies in Fusarium species have highlighted the involvement of G-protein-coupled receptor STE2 in mediating polarized hyphal growth towards host released peroxidases but the underlying molecular mechanisms remain poorly characterized. Here we investigated another GPCR, STE3 in Fusarium graminearum, as a mediator of fungal hyphal chemotropism and pathogenicity
