Confocal microscopy of haustoria from wheat-Puccinia triticina infected tissue. Seedling stage plant specimens examined under laser scanning Alexa Fluor 488 confocal microscope (a, b). a At 20 hpi, formation of intercellular primary infection hyphae (IH), differentiated into haustorial mother cells (HMC) once in contact with mesophyll cells of host. b Haustorial mother cells penetrated through the host mesophyll cells wall to form haustorium (H)
