Challenges and Approaches to Genotyping Repetitive DNA

G3: Genes, Genomes, Genetics, 2020
Individuals within a species can exhibit vast variation in copy number of repetitive DNA elements. This variation may contribute to complex traits such as lifespan and disease, yet it is only infrequently considered in genotype-phenotype associations ...

Losing DNA methylation at repetitive elements and breaking bad

Epigenetics & Chromatin, 2021
Background DNA methylation is an epigenetic chromatin mark that allows heterochromatin formation and gene silencing. It has a fundamental role in preserving genome stability (including chromosome stability) by controlling both gene expression and ...

Multivariable Repetitive-predictive Controllers using Frequency Decomposition [PDF]

, 2012
Repetitive control is a methodology for the tracking of a periodic reference signal. This paper develops a new approach to repetitive control systems design using receding horizon control with frequency decomposition of the reference signal.

Chromosomal mapping of two Mariner-like elements in the grasshopper Abracris flavolineata (Orthoptera: Acrididae) reveals enrichment in euchromatin

European Journal of Entomology, 2014
The occurrence of transposable elements (TEs) is a ubiquitous characteristic of eukaryotic genomes, and these sequences are highly abundant in some species. Due to their large genomes, grasshoppers (Orthoptera) appear to be potentially good candidates in

Potential of Herbariomics for Studying Repetitive DNA in Angiosperms

Frontiers in Ecology and Evolution, 2018
Repetitive DNA has an important role in angiosperm genomes and is relevant to our understanding of genome size variation, polyploidisation and genome dynamics more broadly.
