Phylogenetic analysis and cis-acting elements analysis in the promoter regions of BES/BZR genes from wheat and foxtail millet. All identified cis-acting elements and those related to responses to phytohormone and environmental stimuli were shown in (A) and (B) with phylogenetic analysis, respectively. Left panel: Unrooted phylogenetic tree reconstructed on the basis of promoter sequences of BES/BZR genes in wheat and foxtail millet using MEGA version 7.0 with the neighbor-joining method (bootstrap value = 1000). Right panel: Distribution of cis-acting elements in promoter regions of BES/BZR genes from wheat and foxtail millet. Boxes in different colors represent the cis-regulatory elements. Scale bar at the bottom indicates length of promoter sequence
