Expression of the defence marker genes OsPBZ1 and OsPR1a in mock‐ or Magnaporthe oryzae‐inoculated leaves of low‐, sufficient‐, or high‐Pi wild‐type (Tainung 67; WT) plants. Quantitative reverse transcription PCR was carried out at the indicated times after inoculation using the rice Ubiquitin 5 gene as the internal control. Bars represent means of three biological replicates, each one from a pool of three different plants ± SEM (t test, *p ≤ .05, **p < .005, ***p < .0001)
