Abstract
A developmental expression atlas, At-TAX, based on whole-genome tiling arrays, is presented along with associated analysis methods.
Highlights
The generation of genome-wide gene expression data for the reference plant Arabidopsis thaliana yielded important insights into transcriptional control of development, with genome-wide expression maps having become an indispensable tool for the research community
We present an RNA expression atlas, Arabidopsis thaliana Tiling Array Express (At-TAX), of the A. thaliana reference strain Col-0 based on the GeneChip® Arabidopsis Tiling 1.0R Array
Expression data have been collected across a series of tissues and developmental stages for the vast majority of annotated genes, including more than 9,000 genes that are not represented on the older ATH1 gene expression array
Summary
The generation of genome-wide gene expression data for the reference plant Arabidopsis thaliana yielded important insights into transcriptional control of development, with genome-wide expression maps having become an indispensable tool for the research community. Specific gene expression profiles for various plant organs, developmental stages, growth conditions, treatments, mutants, or even single cell types are available (for example [1,2,3,4,5,6,7]). These data have helped to elucidate transcriptional networks and attending promoter motifs, to uncover gene functions, and to reveal molecular explanations for mutant phenotypes (for review [8]). All users of ATH1 arrays are confronted with a problem; as the number of newly discovered genes is rising, expression analysis becomes more and more restricted
