Live-cell imaging elaborating epidermal invasion and vascular proliferation/colonization strategy of Verticillium dahliae in host plants.

ABSTRACT: The soilborne ascomycete fungus Verticillium dahliae causes destructive vascular wilt disease in hundreds of dicotyledonous plant species. However, our understanding of the early invasion from the epidermis to the vasculature and the prompt proliferation and colonization in the xylem tissues remains poor. To elaborate the detailed infection strategy of V. dahliae in host plants, we traced the whole infection process of V. dahliae by live-cell imaging combined with high-resolution scanning electron microscopy. The 4D image series demonstrated that the apex of invading hyphae becomes tapered and directly invades the intercellular space of root epidermal cells at the initial infection. Following successful epidermal invasion, the invading hyphae extend in the intercellular space of the root c
