Clustergram representing correlation between transcriptomes from cold treatment conditions and stress treated plants.

<p>The transcriptomes of the WGA (2h, 10h, and 24h) experiments are clustered according to their similarity to each stress index, which are shown on the horizontal axis. The indexes for drought, osmotic, salt, cold and heat stress are from Kilian <i>et al</i>. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066511#pone.0066511-Kilian1" target="_blank">[4]</a>. The transcriptomes screened by vector-based analysis are shown on the vertical axis. Correlation values are color-coded from blue (negative correlation) to red (positive correlation). Neutral correlation values are white. The data for 2h and 10h were obtained from Matsui <i>et al</i>. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066511#pone.0066511-Matsui1" target="_blank">[11]</a>
