PMR4 (Powdery Mildew Resistant 4) contributes to the penetration resistance to Oidium heveae HN1106 in Arabidopsis. Four‐week‐old plants were inoculated with O. heveae HN1106. (A) The symptoms were examined for Col‐0 and the pmr4 mutant at 5 days post‐inoculation (dpi). The numbers below each panel indicate the number of leaves surveyed (denominator) and the number of leaves showing the phenotypes (numerator). (B) Infected leaves of Col‐0 and the pmr4 mutant were stained with trypan blue at 5 dpi. Bar, 50 μm. (C) The mRNA abundance of PR1 (Pathogenesis‐Related 1) was determined at 0 and 5 dpi. Data represent the mean ± standard deviation (SD) of three RNA replicates. *Significant difference from Col‐0 (Student's t‐test, P < 0.05). (D) The mRNA abundance of PR5 was determined at 0 and 5 dpi. Data represent the mean ± SD of three RNA replicates. *Significant difference from Col‐0 (Student's t‐test, P < 0.05). (E) Quantitative assessment of host cell entry rates. Data represent the mean ± SD of three experiments, each based on five to seven leaves per plant line. *Significant difference from Col‐0 (Student's t‐test, P < 0.05). These experiments were repeated twice with similar results.
