Putative conserved motifs in the promoters of CsGAoxs according to phylogenetic relationship. The 3 motifs were identified online using the MEME with 1.5 kb upstream region of start condon of all CsGAox genes. The following parameters “nmotifs 3, minw 6, maxw 20, minsites 30, maxsites 100” were used in MEME. Different motifs are indicated by different colors and are numbered 1–3. The logos of 3 conserved domain sequences, which were shown on the top right corner, were obtained from MEME Suite website. The bit score shows the information content of each position in the amino acid sequence.
