AtGenExpress is a multinational coordinated effort to uncover the transcriptome of the multicellular model organism Arabidopsis thaliana. This large collaborative project will combine resources of gene expression patterns using Affymetrix GeneChip across the whole plant-life cycle.


To find biological relationships among experiments available in public databases, correlations of transcriptome experiments were analyzed by module-based correlation approach, and then presented in networks.
This version is specific for transcriptome data about phytohormones.
Genome viewer with data focusing on exon combinations from RNA sequencing analysis under nutient deficiencies. 

Tools under development (not open for public access)

AtCAST (Arabidopsis thaliana transcriptome profile correlation analysis tool) is a web-based database with tools to analyze microarray and RNA-seq data. AtCAST provides basic statistical analysis of differentially expressed genes, its visualization by plots, gene ontology term enrichment (GO) analysis and Experiment-Experiment relation analysis using automatically selected marker gene module. New features: GSES, fRMA normalization with R data package. Coming soon...
This version is for Tomato transcriptome data.
