RT-PCR analysis of <i>OsCESA7</i> expression.

<p>(A) Semiquantitative RT-PCR analysis of <i>OsCESA9</i> expression. (B) Real-time RT-PCR analysis of <i>OsCESA7</i> expression. Total RNA was extracted from leaf sheaths, leaf blades, and roots at the seedling stage and from culms and panicles at the mature stage of wild-type plants. The rice <i>ACTIN1</i> gene was used as a control for equal loading. Values shown are averages of four replicates. Bars represent standard errors.
