Differential transcriptional regulation among Arabidopsis accessions

Among five accessions 7,508 probe sets with no detectable genomic sequence variations were identified on the basis of the comparative genomic hybridization to the Arabidopsis GeneChip microarray, and used for accession-specific transcriptome analysis, identifying 60 genes that were differentially expressed in different accession backgrounds in an organ-dependent manner. Correlation analysis of expression patterns of these 7,508 genes between pairs of accessions identified a group of 65 highly plastic genes with distinct expression patterns in each accession.
