The putative model explains the regulation of Cd acquisition and translocation in the peanut roots under iron deficiency. Gene names highlighted with red or green color indicate that they were upregulated and downregulated by Cd exposure with iron deficiency, respectively. The red and blue lines in the nucleus represent positive and negative correlations between TFs and AhOPTs, respectively. The localization of these genes was based on the data previously published in other plant species, such as Arabidopsis and rice.
