CoP is ...

a database management system for understanding plant gene function by associating between co-expressed genes and biological processes in plants. Information on biological processes is based on Gene Ontology biological process. CoP is composed of multiple databases that are based on information about gene co-expression, specific gene expression, biological process, metabolic pathway and are mutually interconnected. The omics data in CoP were obtained from the NCBI, TAIR, and GRAMENE databases. Co-expression analyses in CoP were executed using the Confeito algorithm (Ogata et al., Genome Informatics , 23:117-127, 2009; not yet available on line), an approach based on co-expression network analysis.

Requirements

To display a co-expression network in the page of a co-expression module, the SVG viewer is required.

The viewer is available at Adobe SVG Viewer download area.

The CoP database was validated using Internet Explorer 8.0 and Firefox 3.5.7 for Windows.

This version ...

has been released at November 11th, 2009.
It includes co-expression analyses based on 10022 DNA microarray data; i.e.,

5257 assays of Arabidopsis thaliana
95 assays of poplar (Populus trichocarpa)
2994 assays of soy bean (Glycine max)
403 assays of barley (Hordeum vulgare)
432 assays of rice (Oryza sativa)
368 assays of wheat (Triticum aestivum)
210 assays of grape (Vitis vinifera)
263 assays of maize (Zea mays).

Data sources for this version

Arabidopsis genes: TAIR9_functional_description, dated at 20090702

Arabidopsis GO terms: gene_association.tair, dated at 20091028

Rice GO terms: gene_association.gramene_oryza, dated at 20090924

For Arabidopsis co-expression analysis, an approach using experiments in which genes are specifically expressed has been added.

The future versions will ...

present a co-expression analysis in the different design of poplar microarray data and a mode to search genes that are specifically expressed in multiple experiments.
