Relative expression levels based on Z-score analysis. (a) Relative expression levels in early seed development stages (seed 10-DAF, seed 14-DAF and seed 21-DAF, (b) late seed development stages (seed 25-DAF, seed 28-DAF, seed 35-DAF and seed 42-DAF, (c) aerial tissues (leaf, flower, pod, pod-shell 10-DAF and pod-shell 14-DAF, and (d) underground tissues (root and nodule) were visualized using a Z-score plot. High Z-score values indicate genes with tissue specificity.
