TranscriptomicsExtensive demethylation of repetitive elements during seed development underlies gene imprinting
DNA methylation is an epigenetic mark associated with transposable element silencing and gene imprinting in flowering plants and mammals. In plants, imprinting occurs in the endosperm, which nourishes the embryo during seed development. We have profiled Arabidopsis DNA methylation genome-wide in the...

TranscriptomicsAllele specific mRNA-seq expression profiling in Arabidopsis thaliana Col and Ler reciprocal F1 hybrid embryo and endosperm
High throughput Illumina sequencing of poly-A selected RNA from Arabidopsis Col and Ler reciprocal F1 hybrid embryo and endosperm tissue isolated at 6-7 days after pollination to identify imprinted genes. Examination of parent-of-origin specific and total gene expression in seed tissues.

TranscriptomicsNatural epigenetic polymorphisms lead to intraspecific variation in Arabidopsis gene imprinting: allele specific mRNA-seq expression profiling in Arabidopsis thaliana Col, Ler, and Cvi parental and reciprocal F1 hybrid embryo and endosperm
Imprinted gene expression occurs during seed development in plants and is closely tied to differential DNA methylation of maternal and paternal alleles, particularly at proximal transposable elements (TEs). Since the epigenetic modification of TEs can vary within species, we investigated intraspecif...

GenomicsNatural epigenetic polymorphisms lead to intraspecific variation in Arabidopsis gene imprinting: BS-seq of Arabidopsis thaliana Col, Ler, and Cvi parental and reciprocal F1 hybrid embryo and endosperm
Imprinted gene expression occurs during seed development in plants and is associated with differential DNA methylation of parental alleles, particularly at proximal transposable elements (TEs). Imprinting variability could contribute to observed parent-of-origin effects on seed development. We inves...

TranscriptomicsConserved imprinting associated with unique epigenetic signatures in the Arabidopsis genus
In plants, imprinted gene expression occurs in endosperm seed tissue and can be associated with differential DNA methylation between maternal and paternal alleles. Imprinting is theorized to have been selected for because of conflict between parental genomes in offspring, but most studies of imprint...
