Hypermethylated LTR retrotransposon exhibits enhancer activity

Epigenetics, 2017
LTR retrotransposons are repetitive DNA elements comprising ∼10% of the human genome. They are silenced by hypermethylation of cytosines in CpG dinucleotides and are considered parasitic DNA serving no useful function for the host genome.

A retrotransposon-based-strategy for the assessment of genetic and epigenetic stability of oil palm embryogenic suspensions [PDF]

, 2012
Clonal regenerants of oil palm (Elaeis guineensis Jacq) can display a detrimental variant phenotype called mantled which affects the floral morphology of adult palms thus lowering oil yields in clonal offspring.

Chromodomains and LTR retrotransposons in plants [PDF]

Communicative & Integrative Biology, 2009
A chromodomain is a domain contained in various proteins involved in chromatin remodeling and the regulation of gene expression in eukaryotes during development. Chromodomains perform a wide range of diverse functions including chromatin targeting and interactions between different proteins, RNA and DNA.

MTV sings jubilation for telomere biology in Drosophila

Fly, 2018
Telomere protects the ends of linear chromosomes. Telomere dysfunction fuels genome instability that can lead to diseases such as cancer. For over 30 years, Drosophila has fascinated the field as the only major model organism that does not rely on the ...

Advancements in hybrid rice production: improvements in male sterility and synthetic apomixis for sustainable agriculture

Plant Biotechnology Journal, EarlyView.
Summary Rice serves as a staple food for approximately half of the world's population, and enhanced yields from hybrid rice play a crucial role in ensuring food security and augmenting incomes. However, the annual purchase and high cost of hybrid seeds hinder widespread hybrid rice adoption.

Translocation of a 190-kb mitochondrial fragment into rice chromosome 12 followed by the integration of four retrotransposons

International Journal of Biological Sciences, 2005
A 190-kb mitochondrial DNA sequence interrupted by seven foreign DNA segments was identified in rice chromosome 12. This fragment is the largest mitochondrial fragment translocated into the rice nuclear genome.

Activity and Silencing of Transposable Elements in C. elegans

DNA
Since the discovery of transposable elements (TEs) in maize in the 1940s by Barbara McClintock transposable elements have been described as junk, as selfish elements with no benefit to the host, and more recently as major determinants of genome structure
