TranscriptomicsTranscription profiling of field-caught permethrin-resistant Anopheles gambiae shows over-expression of CYP6P3, a P450 that metabolizes pyrethroids
Field-caught permethrin-resistant Anopheles gambiae s.s. overexpress CYP6P3, a P450 that metabolizes pyrethroids
ORGANISM(S): Anopheles gambiae s.s.

TranscriptomicsParent-of-origin effects on gene expression and DNA methylation in the maize endosperm
Imprinting describes the differential expression of alleles based upon their parent of origin. Deep sequencing of RNAs from maize endosperm and embryo tissue 14 days after pollination was used to identify imprinted genes among a set of ~12,000 genes that were expressed and contained sequence polymo...

TranscriptomicsEpigenetic and genetic influences on DNA methylation variation in maize populations
DNA methylation is a chromatin modification that is frequently associated with epigenetic regulation in plants and mammals. However, other genetic changes such as transposon insertions also can lead to changes in DNA methylation levels. Genome-wide profiles of DNA methylation levels for 20 maize i...

TranscriptomicsHeritable epigenetic variation among maize inbreds
Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. Methylation of cytosine residues provides a mechanism for the inheritance of epigenetic information. We have profiled the distribution of DNA methylation in the large, complex genome of Zea m...

TranscriptomicsGenomic Distribution of Maize Facultative Heterochromatin Marked by Trimethylation of H3K27
Trimethylation of histone H3 lysine 27 (H3K27me3) plays a critical role in regulating gene expression during plant and animal development. We characterized the genome-wide distribution of H3K27me3 in five developmentally distinct tissues in maize plants of two genetic backgrounds, B73 and Mo17, rep...

TranscriptomicsSpreading of heterochromatin is limited to specific families of maize retrotransposons
Transposable elements have the potential to act as controlling elements to influence the expression of genes. The current paradigm suggests that heterochromatic silencing can spread beyond the borders of the transposable element and influence the chromatin state of neighboring low-copy sequences. ...

TranscriptomicsVariation in DNA methylation patterns more common among maize inbreds than among tissues
Epigenetic marks such as DNA methylation can act as heritable marks on a genome leading to unique regulation of genomic sequences. As a transient mark, DNA methylation has been identified as a possible mechanism for reversible genetic regulation of cells derived through either mitotic or meiotic cel...
