Effects of different carbohydrates on the expression of <i>hrpX</i>, <i>hrpG</i> and <i>fbaB</i> in <i>X. oryzae</i> pv. <i>oryzicola</i>.

<p>RNAs were isolated from cultures of the wild-type RS105 strain and the <i>fbaB</i> deletion mutant RΔ<i>fbaB</i> grown in NY medium alone and NY supplemented with 0.5% of various carbohydrates for 16 h. The relative mRNAs levels of <i>hrpX</i>, <i>hrpG</i> and <i>fbaB</i> genes were calculated by real-time quantitative RT-PCR with respect to the level of the corresponding transcript in the wild-type RS105 cultured in NY medium alone. Data presented are the means ± SD of triplicate measurements from a representative experiment; similar results were obtained in two other independent experiments.
