Figures & data
Fig. 1. Quantitative analysis of penetration resistance to M. oryzae in Arabidopsis mutants.
Notes: Mean frequency of M. oryzae penetration into Arabidopsis mutants at 72-h post-inoculation (hpi) expressed as percentage of the total number of infection sites. Values are means ± standard errors, n = 3 independent experiments. Bars sharing the same lowercase letters are not significantly different (p > 0.05). col, Col-0; p2, pen2; p2 er, pen2 er.
Fig. 2. Quantitative analysis of post-penetration resistance to M. oryzae in Arabidopsis mutants.
Notes: (A) Mean length of infection hyphae was measured at 72 hpi. Values are means ± standard errors (n = 6) from three biological replicates. Bars sharing the same lowercase letters are not significantly different (p > 0.05); (B) Mean frequency of M. oryzae penetration with branched hyphae into Arabidopsis mutants at 72 hpi expressed as a percentage of penetrated cells. Values are means ± standard errors, n = 3 independent experiments. Bars sharing the same lowercase letters are not significantly different (p > 0.05). p2, pen2; p2 er, pen2 er.
Fig. 3. Accumulation of callose at infection sites in Arabidopsis mutants.
Notes: (A) Light microscopic view of infection sites of pen2 plants at 72 hpi; (B) Callose deposition at infection sites in (A) as visualized by fluorescence microscopy following aniline blue staining; (C) Light microscopic view of infection sites of pen2 er plants at 72 hpi; (D) Callose deposition at infection sites in (C) as visualized by fluorescence microscopy following aniline blue staining. a, Appressorium. Bars = 50 µm.
