Comparison of transcription profiles from SSH-derived macro-arrays and SuperSAGE. Comparison of transcription profiles from SSH-derived macro-arrays (lane 1, Boominathan et al. 2005) and SuperSAGE, respectively (lane 2). RNA was harvested 5 h (1) or 6 h , respectively, after onset of stress. The two original data sets were linked through their UniProt IDs representing each cDNA and 26 bp Tag, respectively. A total of 186 26 bp tags were compared. Transcripts are clustered in groups, that follow similar expression patterns. Four main sections (detailed informations in Table 7) can be distinguished: Section A: Upregulated transcripts on the macroarray versus constitutive 26 bp tags. Section B, D: Non-corresponding macroarray and SuperSAGE transcript profiles. Section C: Upregulated transcripts on the macroarray and upregulated 26 bp tags.
