TranscriptomicsTranscription profiling of maize segmental aneuploid to study phenotypic and gene expression changes associated with aneuploidy
ABSTRACT: BACKGROUND: While changes in chromosome number that result in aneuploidy are associated with phenotypic consequences such as Down syndrome and cancer, the molecular causes of specific phenotypes and genome-wide expression changes that occur in aneuploids are still being elucidated. RESULTS...

TranscriptomicsZea mays Transcriptome or Gene expression
Transcriptome of Zea mays genotypes under control and stress conditions. Stress conditions include heat, cold, salt, and UV. We extracted and sequenced RNA from 14 day old seedlings of inbred lines B73, Mo17 and Oh43 grown using standard conditions as well as seedlings that had been subjected to col...

TranscriptomicsZea mays Transcriptome or Gene expression
In many eukaryotes, reproduction involves contributions of genetic material from two parents. At some genes there are parent-of-origin differences in the expression of the maternal and paternal alleles of a gene and this is referred to as imprinting. The analysis of allele-specific expression in sev...

TranscriptomicsVariation in DNA methylation patterns more common among maize inbreds than among tissues
Transposable elements (TEs) have the potential to act as controlling elements to influence the expression of genes and are often subject to heterochromatic silencing. The current paradigm suggests that heterochromatic silencing can spread beyond the borders of TEs and influence the chromatin state o...

TranscriptomicsHigh-density deletion bin map of wheat chromosome 7B
Using 270K Nimblegen Comparative Genomic Hybridization (CGH) array on a set of cv. Chinese Spring deletion lines, a total of 3,671 sequence contigs and scaffolds (~7.8% of chromosome 7B physical length) were mapped into nine deletion bins. In our study we have developed 270K CGH Nimblegen array cont...

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...

TranscriptomicsMaize Inbreds Exhibit High Levels of Copy Number Variation (CNV) and Presence/Absence Variation (PAV) in Genome Content
Following the domestication of maize over the past ,10,000 years, breeders have exploited the extensive genetic diversity of this species to mold its phenotype to meet human needs. The extent of structural variation, including copy number variation (CNV) and presence/absence variation (PAV), which a...
