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
