Open AccessMap** responsive genomic elements to heat stress in a maize diversity panel
Many plant species exhibit genetic variation for co** with environmental stress. However, there are still limited approaches to effectively uncover the genomic region that regulates distinct responsive patte...

Open AccessDNA demethylation affects imprinted gene expression in maize endosperm
DNA demethylation occurs in many species and is involved in diverse biological processes. However, the occurrence and role of DNA demethylation in maize remain unknown.

Characterizing introgression-by-environment interactions using maize near isogenic lines
Significant introgression-by-environment interactions are observed for traits throughout development from small introgressed segments of the genome.

Article
Open AccessUsing multiple reference genomes to identify and resolve annotation inconsistencies
Advances in sequencing technologies have led to the release of reference genomes and annotations for multiple individuals within more well-studied systems. While each of these new genome assemblies shares sign...

Article
Open AccessPopulation-level analysis reveals the widespread occurrence and phenotypic consequence of DNA methylation variation not tagged by genetic variation in maize
DNA methylation can provide a source of heritable information that is sometimes entirely uncoupled from genetic variation. However, the extent of this uncoupling and the roles of DNA methylation in sha** div...

Open AccessGenome-wide nucleotide patterns and potential mechanisms of genome divergence following domestication in maize and soybean
Plant domestication provides a unique model to study genome evolution. Many studies have been conducted to examine genes, genetic diversity, genome structure, and epigenome changes associated with domesticatio...

Article
Open AccessCorrection to: Genome-wide discovery and characterization of maize long non-coding RNAs
The original version [1] of this article unfortunately contained a mistake. The additive effects of the eQTLs of lncRNAs were flipped, meaning that the base allele in the contrast to derive the additive effect...

Chapter
The Maize Methylome
DNA methylation is a chromatin modification that has generally been associated with gene silencing or heterochromatin. Plants have mechanisms to allow for the stable inheritance of DNA methylation through mito...

Article
Open AccessThe repetitive landscape of the 5100 Mbp barley genome
While transposable elements (TEs) comprise the bulk of plant genomic DNA, how they contribute to genome structure and organization is still poorly understood. Especially in large genomes where TEs make the maj...

Article
Open AccessGenome-wide map** of transcriptional enhancer candidates using DNA and chromatin features in maize
While most cells in multicellular organisms carry the same genetic information, in each cell type only a subset of genes is being transcribed. Such differentiation in gene expression depends, for a large part,...

Article
Open AccessCo-expression network analysis of duplicate genes in maize (Zea mays L.) reveals no subgenome bias
Gene duplication is prevalent in many species and can result in coding and regulatory divergence. Gene duplications can be classified as whole genome duplication (WGD), tandem and inserted (non-syntenic). In m...

Article
Open AccessWidespread natural variation of DNA methylation within angiosperms
DNA methylation is an important feature of plant epigenomes, involved in the formation of heterochromatin and affecting gene expression. Extensive variation of DNA methylation patterns within a species has bee...

Article
Utilization of deletion bins to anchor and order sequences along the wheat 7B chromosome
A total of 3,671 sequence contigs and scaffolds were mapped to deletion bins on wheat chromosome 7B providing a foundation for develo** high-resolution integrated physical map for this chromo...

Article
Open AccessGenome-wide discovery and characterization of maize long non-coding RNAs
Long non-coding RNAs (lncRNAs) are transcripts that are 200 bp or longer, do not encode proteins, and potentially play important roles in eukaryotic gene regulation. However, the number, characteristics and ex...

Article
Open AccessDistribution, functional impact, and origin mechanisms of copy number variation in the barley genome
There is growing evidence for the prevalence of copy number variation (CNV) and its role in phenotypic variation in many eukaryotic species. Here we use array comparative genomic hybridization to explore the e...

Chapter
Imprinting in Maize
Genomic imprinting in the maize endosperm results in differential expression of maternal and paternal alleles depending on their parental origin. The availability of sequence polymorphisms between different ma...

Open AccessProfiling expression changes caused by a segmental aneuploid in maize
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...
