Gene retention, fractionation and subgenome differences in polyploid plants
All natural plant species are evolved from ancient polyploids. Polyloidization plays an
important role in plant genome evolution, species divergence and crop domestication. We …

Coevolution between transposable elements and recombination
One of the most striking patterns of genome structure is the tight, typically negative,
association between transposable elements (TEs) and meiotic recombination rates. While …

Transposable elements contribute to activation of maize genes in response to abiotic stress
Transposable elements (TEs) account for a large portion of the genome in many eukaryotic
species. Despite their reputation as “junk” DNA or genomic parasites deleterious for the …

Stress induced gene expression drives transient DNA methylation changes at adjacent repetitive elements
Cytosine DNA methylation (mC) is a genome modification that can regulate the expression
of coding and non-coding genetic elements. However, little is known about the involvement …

Exploiting induced and natural epigenetic variation for crop improvement
NM Springer, RJ Schmitz - Nature reviews genetics, 2017 - nature.com
Plant breeding has traditionally relied on combining the genetic diversity present within a

Double-edged sword: the evolutionary consequences of the epigenetic silencing of transposable elements
Transposable elements (TEs) are genomic parasites that selfishly replicate at the expense of
host fitness. Fifty years of evolutionary studies of TEs have concentrated on the deleterious …

Genome-wide discovery and characterization of maize long non-coding RNAs
Abstract Background 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 …

RNA-directed DNA methylation enforces boundaries between heterochromatin and euchromatin in the maize genome
The maize genome is relatively large (∼ 2.3 Gb) and has a complex organization of
interspersed genes and transposable elements, which necessitates frequent boundaries …
