Fig. 6From: Genome-wide analysis of polyamine biosynthesis genes in wheat reveals gene expression specificity and involvement of STRE and MYB-elements in regulating polyamines under droughtCis-regulatory elements in the promoter region of PA biosynthesis genes in wheat. A Pie distribution of the sum of 100 identified CREs in wheat PA biosynthesis promoters classified into seven categories. B Position of the identified CREs in wheat 2000 bp promoter. C Distribution of each CREs category in each wheat promoter, number of elements of each CREs category is represented by a different colour in the histogramBack to article page
