AREX: The Arabidopsis Gene Expression Database

Welcome

If you use data from this website, please make sure to cite Birnbaum et al. (2003) and Brady et al. (2007) (more...)

Welcome to Arex, which stores genome-wide (Affymetrix microarray) and gene-specific (in situ, GFP-reporter, etc.) Arabidopsis spatial gene expression data. Currently, Arex only stores data from the root, but we wish to include data from other organs in the future. Use the various types of searches below to search through our database, or use the Database menu on the left to browse.

There is no need to register to browse publicly accessible data. You will need to register first, however, to be able to enter data or view restricted access data, or to be informed of future developments by email.

Please see the About page for more information about the database.

To search the AREX database, please specify what you would like to search for in the drop down menu below and then fill in as many search criteria as you wish.

Expression Pattern Criteria

Experiment Criteria

Explanation Explanation

Provide expression pattern criteria to search through both traditional (reporter, in situ, etc.) and microarray experiments. For traditional experiments data, we will retrieve the experiments that show expression in the tissues that you selected. If you wish to find genes enriched in a set of tissues compared to another, provide criteria for the optional second set of tissues ("Tissues to compare with").

Microarray data criteria: Expression values are from the MAS5 algorithm, and are normalized to 500. To give you an idea of values to use, here are some examples: [when it works, provide examples of results from searches for scarecrow, short-root, etc.]
