Relative expression levels of <i>PAP1</i> and <i>Lc</i> gene in transgenic plants.

<p>(a) Relative expression levels of <i>PAP1</i> or <i>Lc</i> in four transgenic <i>PAP1</i> callus lines (CP1–CP4) or <i>Lc</i> (CL1–CL4) alone. (b) Relative expression levels of <i>PAP1</i> and <i>Lc</i> in transgenic callus lines (C1–C6) co-expressing <i>PAP1</i> and <i>Lc</i>. (c) Relative expression levels of <i>PAP1</i> and <i>Lc</i> in <i>PAP1</i>+<i>Lc</i> transgenic plants. (Expression levels were relative to <i>GAPDH</i>).
