Analysis of resistance to blast fungus in <i>OsPIANK1</i>-overexpressing (OE) rice plants.

<p>(A) Quantitative PCR analysis of <i>OsPIANK1</i> expression in WT and OE plants (3#, 4#, and 6#). Data represent means ± SE of three independent experiments. (B) Lesions in leaves at 6 days after inoculation. The number of expanding lesions (Els) with an area greater than 0.5 mm² per leaf and their mean areas were determined using 10 leaves for WT (Nipponbare) and <i>OsPIANK1</i>-OE plants. Values represent means ± SE. (C) The amount of <i>M. oryzae</i> DNA in the WT and <i>OsPIANK1</i>-OE rice leaves. The leaves were harvested at 6 days after inoculation. Values represent the mean ± SE of three independent experiments. (D) Symptoms of rice blast in <i>OsPIANK1</i>-OE and WT rice plants grown in the greenhouse at 30 days after inoculation with spores of <i>M. oryzae</i> strain guy11. (**,*indicate significant differences between WT and <i>OsPIANK1</i>-OE plants at <i>P</i><0.01 or <i>P</i><0.05, respectively, as determined by the SNK test.).
