Dear colleagues,
We have set up a small Arabidopsis expression atlas (At-TAX) that is
based on whole genome tiling arrays (http://www.weigelworld.org/resources/microarray/at-tax
). This allows for the first time expression analysis of more than
9,000 genes that cannot be analyzed with conventional arrays such as
ATH1. The online tool for expression analysis is available trough http://jsp.weigelworld.org/tileviz/tileviz.jsp
.
We also identified more than a thousand novel transcribed regions in
the genome that are visualized together with single probe raw
intensities in all analyzed samples http://gbrowse.weigelworld.org/cgi-bin/gbrowse/attax/
.
Additional information about the comparison of ATH1 and tiling arrays
for expression analysis, non-polyadenylated transcripts in Arabidopsis
etc., can be found in
