Expression profiles of the components of circadian molecular clock of A. aegypti. The schema is adopted from KEGG database. Each pane shows expression profile of genes (marked by gene symbols) over two complete circadian periods. Light and dark periods are marked on the horizontal axis; vertical axis corresponds to relative abundance of transcripts (see Methods). Green arrows mark positive regulation, red arrows mark negative regulation of gene expression. P+ marks activation by phosphorylation, tr+ and tr- mark positive and negative regulation of transcription.
