Welcome to Diurnal
Diurnal is a web-based tool for accessing the diurnal and circadian genome-wide expression results of genes from several array experiments conducted on common model plants. The expression patterns of particular loci or array probes can be looked up under a variety of different conditions. For each condition, every expression pattern has been modeled using a periodic pattern, which has then been used to estimate the phase of peak expression. These results can be accessed both graphically online and downloaded to your computer for further use. Get Started
Version 2.0 of Diurnal has been released.
The original Diurnal expression data is still available from version 2.0; however, the probes have now been mapped to the latest versions of the genomes. Diurnal is not backwards compatible i.e. locus identifiers from now obsolete annotations cannot be used to find the matching probes and expression patterns.
