Fig 6. Expression profile of BdNAC genes in response to various phytohormones.

Fig 6

(A). Hierarchical clustering of expression profile of BdNAC genes in response to abscisic acid (ABA), ethephone (Eth), jasmonic acid (JA) and salicylic acid (SA) treatments. Three-week-old seedlings were treated with 100 μM ABA, 300 μM ethephon, 100 μM JA and 100 μM SA, respectively. Relative expression levels of the BdNAC genes were analyzed by quantitative real-time RT-PCR (qPCR), and log2-transformed fold-change values were used for creating the heatmap (original data were shown in S8 Fig.). Venn diagram illustrated the distribution of the up-regulated (B) or down-regulated (C) BdNAC genes response to different phytohormone treatments. The common subset of genes regulated by two or more phytohormones was marked by the overlapping circle.
