To cause rice blast disease, the fungus Magnaporthe oryzae produces biotrophic invasive hyphae that secrete effectors at the host-pathogen interface. Effectors facilitate disease development, but some (avirulence effectors) also trigger the host's resistance gene-mediated hypersensitive response and …

Jan 10, 2025 · Rice blast disease is the most serious threat to the global rice production, destroying sufficient rice each year to feed 60 million people [9, 10], but the fungus can also infect over 50...

Jul 12, 2023 · Here, we show that the M. oryzae serine/threonine protein kinase Rim15 promotes biotrophic growth by coordinating cycles of autophagy and glutaminolysis in invasive hyphae.

Rice blast disease is caused by the hemibiotrophic fungus Magnaporthe oryzae, which invades living plant cells using intracellular invasive hyphae (IH) that grow from one cell to the next. The cellular and molecular processes by which this occurs ...

Feb 23, 2007 · Rice blast disease is caused by the hemibiotrophic fungus Magnaporthe oryzae, which invades living plant cells using intracellular invasive hyphae (IH) that grow from one cell to the next. The cellular and molecular processes by which this occurs are not understood.

Here we report that the rice blast fungus Magnaporthe oryzae possesses two distinct secretion systems to target effectors during plant infection. Cytoplasmic effectors, which are delivered into host cells, preferentially accumulate in the biotrophic interfacial complex, a novel plant membrane-rich structure associated with invasive hyphae.

Oct 15, 2015 · 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).

4 days ago · The infective hyphae were observed at lesion edge of rice leaf at 4 dpi. The mCherry-labeled Guy11 spores were used to infect the rice leaves at a concentration of 5 × 10 5 spores mL −1. The rice cell plasma membrane was labeled with PIP2-GFP to visualize cell profiles. The circles indicate the vascular tissues. Scale bars, 20 µm. d) The ...

The rice blast fungus (Magnaporthe oryzae) is an economically important pathogen that infects rice, wheat, and other cereal crops. The fungus enters leaves via dome-shaped appressoria that develop from germinated spores and forms invasive hyphae (IH) that undergo pseudohyphal growth inside the invaded plant cells.

Rice blast disease is caused by the hemibiotrophic fungus Magnaporthe oryzae, which invades living plant cells using intracellular invasive hyphae (IH) that grow from one cell to the next. The cellular and molecular processes by which this occurs are not understood.
