Abstract Whole genome tiling arrays are a key tool for profiling global genetic and expression variation. In this study we present our methods for detecting transcript level variation splicing variation and allele specific expression in Arabidopsis thaliana. We also developed a generalized hidden Markov model for profiling transcribed fragment variation de novo. Our study demonstrates that whole genome tiling arrays are a powerful platform for dissecting natural transcriptome variation at multidimension and high resolution. Background Natural gene expression variation represents perturbations in the cellular network underlying morphological and physiological diversity. It reveals altered signaling pathways that may include early events responsible for phenotypic variation. Gene expression phenotypes are complex traits that map to genetic loci acting in cis and or trans 1-5 . Trans-acting loci affect expression of both alleles of the downstream gene while cis-acting loci represent genetic polymorphisms in the .
