Brachypodium distachyon is a new model plant closely related to wheat and other cereals. In this study, we performed a comprehensive analysis of hormone-regulated genes in Brachypodium distachyon using RNA sequencing technology. Brachypodium distachyon seedlings were treated with eight phytohormones (auxin, cytokinine, brassinosteroid, gibberelline, abscisic acid, ethylene, jasmonate and salicylic acid) and two inhibitors, Brz220 (brassinosteroid biosynthesis inhibitor) and prohexadione (gibberelline biosynthesis inhibitor). The expressions of 1807 genes were regulated in a phytohormone-dependent manner. We compared the data with the phytohormone responses that have reported in rice. Transcriptional responses to hormones are conserved between Bracypodium and rice. Transcriptional regulation by brassinosteroid, gibberellin and ethylene was relatively weaker than those by other hormones. This is consistent with the data obtained from comprehensive analysis of hormone responses reported in Arabidopsis. Brachypodium and Arabidopsis also shared some common transcriptional responses to phytohormones. Alternatively, unique transcriptional responses to phytohormones were observed in Brachypodium. For example, the expressions of ACC synthase genes were up-regulated by auxin treatment in rice and Arabidopsis, but no orthologous ACC synthase gene was up-regulated in Brachypodium. Our results provide information useful to understand the diversity and similarity of hormone-regulated transcriptional responses between eudicots and monocots.
