Expression profiles of <i>SiNAC</i> genes in leaves upon exposure to various abiotic stresses.

<p>14-day-old seedlings were treated to osmotic (15% PEG 6000), salt (150 mM NaCl), and cold (4°C) stresses. Relative expression levels of the <i>SiNAC</i>s were analyzed by qRT-PCR, and the heat maps were created by log2-based fold-change values (mean of three biological replicates) (original data were shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0199262#pone.0199262.s005" target="_blank">S5 Fig</a>).
