Abstract Background Genetic control of gene transcription is a key component in genome evolution. To understand the transcriptional basis of natural variation we have studied genome-wide variations in transcription and characterized the genetic variations in regulatory elements among Arabidopsis accessions. Results Among five accessions Col-0 C24 Ler WS-2 and NO-0 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. Two-way ANOVA analysis has identified 60 genes whose mRNA levels differed in different accession .
