Temporal gene expression profiles. Temporal gene expression profiles containing significantly more genes than expected by chance. (a) Expression profiles during encystation. (b) Expression profiles during excystation. Each box shows a representative expression profile (black line) and profiles of genes assigned to the profile (red lines). The profile ID number is shown in each box. Clusters of related profiles have the same color. The numbers of genes assigned to a profile/cluster are shown to the right. All profiles are shown in Additional file 8 and data for all genes are tabulated in Additional file 4.
