Figure 7

Normalized gene expression patterns of the genes that are part of the superpathway of sulfur amino acid biosynthesis and additional genes discussed in the text. The expression values of each gene are linearly scaled to range from -1 to 1. Here, -1 represents the lowest expression value and 1 indicates a gene's highest expression value. These normalized expression patterns are projected on the green-black-red colormap to derive the heatmap visualization. Separate branches of the pathway are indicated by the grey horizontal lines. For the group denoted as "Additional genes", the grey horizontal lines split the genes in functionally related groups. The magenta boxes and arrows indicate the cultivation parameters, where methionine is used as nitrogen or sulfur source. The magenta ellipses and arrows highlight the expression levels of the SOD and GSH genes under zinc limitation.
