Fig. 8
Analysis of the cis-elements in the promoter regions of soybean ALDH genes. a. Predicted cis-elements in the 1500 bp upstream regions of six GmALDH genes. The names of the cis-elements are indicated at the bottom of the figure. The scale indicates the relative position of each cis-element relative to the translation start codon, ATG. b. Frequency of three drought-responsive cis-elements present in the promoter regions of different groups of soybean ALDHs. The frequencies of ABRE, CRT/DRE, and GTGCnTGC/G cis-elements in up-regulated, down-regulated and non-responsive GmALDH genes under drought stress are shown in different colored bars. Changes in expression were determined by the criteria of P value < 0.05 and │log2 fold change│ ≥ 2 comparing drought-stressed soybean plants with control
