Fluridone suppresses pathogen-induced transcription of ABA biosynthesis and response genes.

<p>(A) through (C). Relative expression of ABA biosynthesis and responsive genes, <i>OsNCED3</i>, <i>OsLip9</i> and <i>OsRab16</i>, in control (Ctrl) and fluridone-pretreated (0.4 µM) IRBB3 leaves inoculated with PXO99. Transcript levels were normalized using eukaryotic elongation factor <i>eEF1α</i> as an internal reference and expressed relative to the normalized expression levels in mock-inoculated control plants at the appropriate time point. Data are means ± SD of two technical and two biological replicates from a representative experiment, each biological replicate representing a pooled sample from 3 individual plants. Two sets of independent experiments were carried out with similar results. Asterisks indicate statistically significant differences per treatment compared to either control (0 dpi) or mock-treated samples (1, 2, 4 and 8 dpi).
