Time-course of numbers of genes called regulated by zinc supplementationin gills of zebrafish. Genes were called significantly regulated with greater than 1.8-fold change, compared to control, and FDR of 0.1 (N = 4 or 5 from each group at each time point). The triangles and solid line show the total number of regulated genes at each time-point, diamonds and short-dashed line give the numbers of up-regulated genes, and the numbers of down-regulated genes are indicated by rectangles and long-dash line.
