Histochemical detection of iron (Fe) in M. oryzae-infected rice (O. sativa cv. Nipponbare, japonica) leaves. Wild-type plants at the three-leaf stage were sprayed with a M. oryzae spore suspension or mock inoculated. At 24–48 h post-inoculation (hpi), the third leaf of each plant was stained with Perls (a) or Perls/DAB (b) (blue and black precipitates, respectively). Scale bar: 100 μm. ap, appressorium; gt, germ tube; ls, lesion; st, stomata; sp, spore
