There are cross-linkages on this web site to several focused databases that provide
calculated transcriptome data with user-friendly interfaces.
AtGenExpress
AtGenExpress is a multinational project designed to uncover the transcriptome of
A. thaliana . The data sets collected in AtGenExpress have been one of the most
comprehensive resources for the Arabidopsis transcriptome described to date
(Kilian et al. 2007 ; Goda et al. 2008 ).
ATTED II
ATTED II is a database that provides co-expression analysis calculated from pub-
licly available Arabidopsis ATH1 GeneChip data (Obayashi et al. 2007 , 2009 ). Co-
expression analysis generated from collected transcriptomes has aided gene expres-
sion studies in plants.
GeneInvestigator
Genevestigator, which is a reference expression database and meta-analysis system,
also provides summary information from hundreds of microarray experiments on
various organisms, including Arabidopsis, barley and soybean, with an easyinter-
face forresults (Zimmermann et al. 2004 ).
Electronic Fluorescence Pictograph (eFP)
The electronic fluorescent pictograph (eFP) browser provides gene expression
patterns collected from Arabidopsis , poplar, Medicago , rice and barley via a user-
friendly program (Winter et al. 2007 ). The Bio-Array resources on this site, how-
ever, directs most of the information to Arabidopsis , and the 3DDI site provides
three dimensional display data designed to generate extendible models for plants.
AREX
The Arabidopsis Gene Expression Database AREX is a web site that provides data
of high-resolution gene expression patterns of root tissues in Arabidopsis (Birn-
baum et al. 2003 ; Brady et al. 2007).
