Effect of pH on the transcriptional profile changes in iron-deficient plants. a GO biological process term analysis result for the 186 common DEGs between high-pH and low-pH datasets as summarized by REVIGO. Bubble color indicates the log10 P value (bubbles of darker color are more significant) and the size indicates the frequency of the GO term in the underlying GO annotation database (bubbles of more general terms are larger). b Venn diagram comparing the DEGs in high-pH, optimal-pH, and low-pH datasets. c Visualization of expression changes of the 12 common DEGs in (b). The x-axis represents the logFC values and the y-axis represents different genes. Low-pH DEGs are from Lager et al. [14]
