Heat map of the real-time quantitative PCR (qRT-PCR) analysis results of PeDREB genes in leaves and roots under drought, low-temperature and high salinity treatments, with three biological and technical replicates.

<p>The expression levels of genes are presented using fold-change values transformed to log₂ format compared to controls. The log₂ (fold-change values) and the color scale are shown at the right of the heat map.</p

Comparison of group/subgroup size between moso bamboo, Arabidopsis and rice AP2/ERF families.

<p>The subclassification was by Nakano et al. (2006) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126657#pone.0126657.ref007" target="_blank">7</a>].</p

The ERF subfamily genes in moso bamboo.

<p>Note: The groups I to IV genes were DREB subfamily genes, the groups V, VI, VI-L, and VII to X genes were ERF subfamily genes.</p><p>The ERF subfamily genes in moso bamboo.</p

Ks and Ka/Ksvalue distributions of the AP2/ERF genes in the genomes of rice and moso bamboo viewed through the frequency distribution of relative Ks and Ka/Ks modes.

<p>Distribution of Ks and Ka/Ks values were obtained from orthologous gene-pairs (A and B) between the moso bamboo and rice genomes, and paralogous gene-pairs (C and D) in the moso bamboo genome. Ka/Ks = 1 indicates neutral selection, Ka/Ks > 1 indicates positive selection and Ka/Ks < 1 indicates purifying selection [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126657#pone.0126657.ref079" target="_blank">79</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126657#pone.0126657.ref080" target="_blank">80</a>].</p
