Fig. 4From: Genome-wide analysis of polyamine biosynthesis genes in wheat reveals gene expression specificity and involvement of STRE and MYB-elements in regulating polyamines under droughtDistribution of conserved motifs. Conserved motifs (left) and their distributions (right) of TaPA biosynthesis proteins predicted by the MEME (Multiple Expectation Maximization for Motif Elicitation). The motifs are represented by different coloured boxes with a corresponding number. The descriptions of the motifs are listed in Table 2Back to article page
