Rice root infection by Fusarium moniliforme or Rhizoctonia solani and its influence on OsPT11 expression. (A–F) Hand cuttings (A, C, and E) and semifine sections (B, D, and F) of control roots (A and B) or roots infected by F. moniliforme (C and D) or R. solani (E and F) at 8 dpi. Control rhizoderm cells appear joined (B, double black arrow). A dense mycelium of F. moniliforme has formed around the root (C and D, double black arrow) and the fungus has penetrated intercellularly (D, black arrow) disorganizing the rhizodermal root layer. A dense mycelium of R. solani has formed around the root (E, double white arrow), disorganizing the rhizodermal root cells. (F) External hyphae of R. solani have attached to the rhizoderm (double black arrows) and have invaginated the root cells (black arrows). (Bars = 10 μm.) (G) Expression of OsPT11. The expression levels of RubQ1 itself and of OsPT11 relative to the expression levels of RubQ1 are shown. The same pattern of expression was observed in an additional experiment.
