Custom cdf files and example scripts for expression analysis with R / Bioconductor can be found here.

Supplementary data

Developmental data:

Raw and normalized array data, files containing the results of expression analysis as well as information on transcribed regions as predicted by mSTAD are available for download from our ftp server. Repeat data and definition files for the mapping of tiling probes to annotated gene models are also provided there (ftp server).

Abiotic stress data:

From our ftp server, raw and normalized array data (also in GEO format) are available. We also provide supplemental files with RMA expression values, lists of genes up- or downregulated under stress as well as lists for broad and narrow-response genes. Finally, you will find genome locations of transcriptionally active regions (TARs) there, as well as additional information on TARs, such as differential expression under stress.

Small RNA mutant data:

Tiling array data are available from our ftp server. Additionally files with RMA expression values, lists of genes up- or downregulated in mutants versus wild type are also provided. There is moreover data for expression of miRNA precursor transcripts for mutants and abiotic stress treatments. Finally, you will find genome locations of transcriptionally active regions (TARs) there, including TARs that accumulate in sRNA processing mutants relative to wild-type plants.
