Figure 3From: Transcriptional profile analysis of E3 ligase and hormone-related genes expressed during wheat grain developmentExpression patterns of differentially expressed E3 ligase genes in developing wheat grain. The differential expression profiles of E3 ligase coding genes at 11 time-points were grouped into two clusters (cluster 1: down-regulated genes; cluster 2: up-regulated genes) using the K-means clustering algorithm. The ratio value (on the log2 scale) of expression is on the y-axis and the time point of development in °Cdays is on the x-axis Among the 173 E3 ligases found to be differentially expressed in this study, 57 and seven had also been identified by Wan et al. [5] and Laudencia-Chingcuanco et al. [33], respectively. Moreover, six E3 ligases were identified in all three studies. The majority of these genes displayed similar average expression profiles in all the studies (see Additional file 3).Back to article page
