From: Diversity and genetics of nitrogen-induced susceptibility to the blast fungus in rice and wheat
Defense gene expression triggered by the Pi1 resistance gene under nitrogen treatment. Rice plants of the C104Lac genotype (containing the Pi1 resistance gene recognizing the avirulent isolate of M. oryzae CL367) were grown under the same conditions except one day before inoculation where they were either treated with no additional nitrogen (0 N) or additional nitrogen (1 N). Uninfected plants (white bars: Mock) were used as controls to compare to infected plants (black bars). The expression of defense-related marker genes (normalized with the actin gene; arbitrary units are given) was measured at the indicated time points after infection (2 and 4 days post inoculation-dpi). The mean and sd of three independent replicates are shown. The statistical differences between mock and inoculated plants are shown (Wilcoxon tests; *: p < 0.05; **p < 0.01; ***: p < 0.001).
