From: Iron homeostasis in Arabidopsis thaliana: transcriptomic analyses reveal novel FIT-regulated genes, iron deficiency marker genes and functional gene networks

Fig. 4

Four-step filtering of FIT-repressed genes using scatterplot analysis of log2 fold changes of gene expression in the respective comparison in seedlings (horizontal) and roots (vertical). The blue dots represent genes that did not match the requirement and were removed in the subsequent step. The yellow dots represent gene expression patterns that matched the requirement and which were used as the input for the subsequent pattern analysis. The respective zero-points are indicated by red crosshairs. The genes filtered in a were used as input in b. The genes filtered in b were used as input in c. The genes filtered in c were used as input in d. The yellow dots in d represent the FIT-repressed genes (Tables 1 and 2)
