WebThe rice blast fungus Magnaporthe oryzae grows inside living host cells. Cytological analyses by live-cell imaging have revealed characteristics of the biotrophic invasion, particularly the extrainvasive hyphal membrane (EIHM) originating from the host plasma membrane and a host membrane-rich structure, biotrophic interfacial complex (BIC). WebMar 30, 2024 · The blast fungus Magnaporthe oryzae secretes cytoplasmic effectors into a specialized biotrophic interfacial complex (BIC) before translocation. Here we show that cytoplasmic effectors within BICs are packaged into dynamic vesicles that can occasionally be found separated from BICs in the host cytoplasm. Live cell imaging with fluorescently ...

WebJul 1, 2016 · The biotrophic interfacial complex (BIC) comprises aggregated EIHM intermingling with the cytosol, symplastic effectors enclosed by a membrane, and the BIC base. (A) Confocal micrographs of a BIC. Images are single optical sections captured at 32 hpi. Bar = 10 μm. (B) Schematic diagram illustrating rice intracellular structure at the BIC. WebJan 26, 2024 · Cytoplasmic effectors are preferentially localized in the biotrophic interfacial complex (BIC), which has been hypothesized as the site of effector translocation into the host cytoplasm [12, 18]. Two stages of BICs have been previously described (Fig. 1a). The tip BIC is associated with the apex of the primary hypha. dwts text numbers to vote

WebMar 21, 2024 · BIC, biotrophic interfacial complex; EIHM, extra-invasive hyphae membrane; IH, invasive hypha; NPC, nuclear pore complex; ROS, reactive oxygen species. Apoplastic effectors are secreted into the interfacial space between the pathogen and plant cells, wherein “chemical warfare” occurs (Doehlemann & Hemetsberger, 2013). WebSep 5, 2024 · After penetration into rice tissue, the blast fungus rapidly switches to biotrophic growth and overcomes plant immunity by secreting effector proteins . At the tip of the primary invasive hypha, a plant-derived membrane-rich structure, the Biotrophic Interfacial Complex (BIC), develops and remains intact as further secondary invasive … WebEffectors of the rice blast fungus Magnaporthe oryzae accumulate and translocate into host cells at a membranous cap known as the biotrophic interfacial complex (BIC) (Valent and Khang 2010). Bacteria rely on specialized secretion pili, such as pseudomonad and xanthomonad T3SSs (Buttner and He 2009). dwts theme next week
