Transcription profiles of the coupled genes <i>Pikh-1</i> and <i>Pikh-2</i>, as assayed by qRT-PCR.

<p>Data represent mean ± standard deviation (n = 3). Similar results were obtained from two independent experiments. Lower case letter (a, b) used to indicate whether the treatment and control means differed at <i>P</i><0.01 or <i>P</i><0.05 level, respectively. The pathogen-inducible gene <i>PBZ1 </i><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0098067#pone.0098067-Ryu1" target="_blank">[46]</a> was used as a reference.
