Querying Arabidopsis microarray data

In the context of the Arabidopsis Functional Genomics Consortium (AFGC),
we have developed two new ways of exploring existing Arabidopsis
microarray data.

First, querying  by Clone Id, GenBank accession or gene product
description retrieves all matching elements on current or past AFGC
microarrays. (Search for your favourite gene and see how it has  behaved
in AFGC microarray experiments).

Secondly , queries may be made by 'phylogenetic profile'. The
phylogenetic profile is created by BLAST searching Arabidopsis sequences
against multiple compled genomes in different categories - e.g eubacteria,
archaea etc. This allows quick screening for elements on the microarrays
that say are specific to plants, or only match prokaryotic sequences. This
approach is experimental - comments are welcome.

These tools are available at:


Follow the links 'Clone List' and 'Phylogenetic profile search'
