Comparison of transcription profiles from Medicago dessicated young radicles (16k-microarray) with SuperSAGE chickpea profiles. Comparison of transcription profiles from dessicated young radicles using the Medicago 16k-microarray (lane 1, Buitink et al. 2006) with SuperSAGE data (lane 2) from drought-stressed chickpea roots. A total of 147 26 bp tags could be linked through the UniProt data base and be used for comparison. Transcripts are clustered in groups, that follow similar expression patterns. Four main categories (detailed informations in Table 8) can be distinguished: Section A: Down-regulated transcripts on the microarray and down-regulated 26 bp tags. Section B: Contrasting microarray expression and SuperSAGE profiles (up- vs. down-regulated). Section C: Contrasting microarray and SuperSAGE profiles (up-regulated vs. constitutive). Section D: Up-regulated or constitutive 16K-microarray and SuperSAGE transcripts, respectivelyTaqMan™ RT-PCR confirmation of SuperSAGE.
