Expression domains of genes across cell types. Data is shown for Arabidopsis phloem companion cells and for the mouse G30-amygdala cells. For each cell type, three plots are given, representing domains of size 2, 3 and 4. For domain size D, we included all genes whose D lowest Nspec(y) values were <D + 0.5, and which had all other Nspec(y) values greater than D + 1. We required that the D cell types with lowest Nspec(y) values include the given cell type (phloem companion or G30-amygdala). Both Spec and raw expression data are shown. Genes are sorted according to the order (left to right) of the D cell types in the gene's domain, and further sorted according to the Spec value of the left-most cell type in the domain. Additionally, genes exhibiting low expression in the cell type of maximal Spec are sorted to the bottom of the plot, allowing these genes to be easily noticed visually.
