Database Description

Publicly available database of co-expressed gene sets would be a valuable tool for a wide variety of experimental designs, including targeting of genes for functional identification or for regulatory investigation. Here, we report the construction of an Arabidopsis thaliana trans-factor and cis-element prediction database (ATTED-II) that provides co-regulated gene relationships based on co-expressed genes deduced from microarray data and the predicted cis elements.

ATTED-II includes the following features:
(i) lists and networks of co-expressed genes calculated from 58 publicly available experimental series, which are composed of 1388 GeneChip data in A. thaliana,
(ii) prediction of cis regulatory elements in the 200-bp region upstream of the transcription start site to predict co-regulated genes amongst the co-expressed genes, and
(iii) visual representation of expression patterns for individual genes. ATTED-II can thus help researchers to clarify the function and regulation of particular genes and gene networks.


Construction of ATTED-II was supported in part by the project "Development of Fundamental Technologies for Controlling the Production of Industrial Materials by Plants" supported by NEDO (New Energy and Industrial Technology Development Organization, Japan) and by CREST (Core Research for Evolutional Science and Technology) of the Japan Science and Technology Agency.
