Non-canonical fungal G-protein coupled receptors promote Fusarium head blight on wheat
Fig 4
The Fusarium graminearum FGRRES_07792 and FGRRES_16221 mutants show reduced floral colonisation, but can penetrate the surface.
Presented are scanning electron micrographs of the inner surface of the palea for the non-infected (mock) wheat tissue, the parental PH-1 strain, plus the Δ16221_3 and Δ07792_3 mutants 2 days post infection. Inserts in each panel are higher magnification images of infection structures indicated. White arrow = infection structures. Black arrow = runner hyphae. Bar = 100 μm.
