Global analysis of allele-specific expression in Arabidopsis thaliana.
Gene expression is a complex trait determined by various genetic and nongenetic factors. Among the genetic factors, allelic difference may play a critical role in gene regulation. In this study we globally dissected cis (allelic) and trans sources of genetic variation in F(1) hybrids between two Arabidopsis thaliana wild accessions, Columbia (Col) and Vancouver (Van), using a new high-density S...
متن کاملAllele-specific histone modifications regulate expression of the Dlk1-Gtl2 imprinted domain.
Dlk1 and Gtl2 are reciprocally expressed imprinted genes located on mouse chromosome 12. The Dlk1-Gtl2 locus carries three differentially methylated regions (DMRs), which are methylated only on the paternal allele. Of these, the intergenic (IG) DMR, located 12 kb upstream of Gtl2, is required for proper imprinting of linked genes on the maternal chromosome, while the Gtl2 DMR, located across th...
متن کاملSNP-specific array-based allele-specific expression analysis.
We have developed an optimized array-based approach for customizable allele-specific gene expression (ASE) analysis. The central features of the approach are the ability to select SNPs at will for detection, and the absence of need to PCR amplify the target. A surprisingly long probe length (39-49 nt) was needed for allelic discrimination. Reconstitution experiments demonstrate linearity of ASE...
متن کاملAllele-specific gene expression uncovered.
Genetic variation in populations can result in variation in levels of gene expression but the extent to which this occurs has been unclear. In this article, recent studies of allele-specific expression among autosomal non-imprinted genes are reviewed. These new data provide evidence that differential expression is relatively common and that allelic differences are heritable and can be highly co...
متن کاملIdentification of Transcriptome SNPs for Assessing Allele-Specific Gene Expression in a Super-Hybrid Rice Xieyou9308
Hybridization, a common process in nature, can give rise to a vast reservoir of allelic variants. Combination of these allelic variants may result in novel patterns of gene action and is thought to contribute to heterosis. In this study, we analyzed genome-wide allele-specific gene expression (ASGE) in the super-hybrid rice variety Xieyou9308 using RNA sequencing technology (RNA-Seq). We identi...
