Evolutionary History of LTR Retrotransposon Chromodomains in Plants [PDF]

International Journal of Plant Genomics, 2012
Chromodomain-containing LTR retrotransposons are one of the most successful groups of mobile elements in plant genomes. Previously, we demonstrated that two types of chromodomains (CHDs) are carried by plant LTR retrotransposons. Chromodomains from group I (CHD_I) were detected only in Tcn1-like LTR retrotransposons from nonseed plants such as mosses ...

Retrotranspositions in orthologous regions of closely related grass species

BMC Evolutionary Biology, 2006
Background Retrotransposons are commonly occurring eukaryotic transposable elements (TEs). Among these, long terminal repeat (LTR) retrotransposons are the most abundant TEs and can comprise 50–90% of the genome in higher plants.

CR1 clade of non-LTR retrotransposons from Maculinea butterflies (Lepidoptera: Lycaenidae): evidence for recent horizontal transmission

BMC Evolutionary Biology, 2007
Background Non-long terminal repeat (non-LTR) retrotransposons are mobile genetic elements that propagate themselves by reverse transcription of an RNA intermediate. Non-LTR retrotransposons are known to evolve mainly via vertical transmission and random

Lost in translation : The biogenesis of non-LTR retrotransposon proteins

, 2013
This research was supported by UK Biotechnology and Biological Sciences Research Council (BBSRC) and the Wellcome Trust.“Young” APE-type non-LTR retrotransposons (non-LTRs) typically encode two open reading frames (ORFs 1 and 2).

APE-type non-LTR retrotransposons of multicellular organisms encode virus-like 2A oligopeptide sequences, which mediate translational recoding during protein synthesis

, 2013
2A oligopeptide sequences (“2As”) mediate a cotranslational recoding event termed “ribosome skipping.” Previously we demonstrated the activity of 2As (and “2A-like sequences”) within a wide range of animal RNA virus genomes and non-long terminal repeat ...

3D Chromatin Architecture Provides Insights Into Leaf Trait Variation Among Pear Species

Advanced Science, EarlyView.
ABSTRACT Three‐dimensional (3D) chromatin architecture plays a fundamental role in eukaryotic gene regulations, its functional significance in perennial fruit trees remains poorly characterized despite extensive applications in crop genomics. Here, we developed high‐resolution (∼5 kb) Hi‐C maps of Pyrus and compared 3D genomic architecture of three ...

Haplotype‐Resolved 3D Genomic Landscapes and Their Impacts on Agronomic Traits in Grapevine

Advanced Science, EarlyView.
This study presents a haplotype‐resolved 3D genomic landscape of grapevine, revealing that structural variations (SVs) are closely associated with phased topologically associating domain (TAD) boundary transitions. These rearrangements coordinate with allele‐specific DNA methylation (ASM) and allele‐biased gene expression (ASE) to shape key agronomic ...

Comprehensive DNA Methylation Analysis of Retrotransposons in Male Germ Cells

Cell Reports, 2015
De novo DNA methylation of retrotransposons is critical for silencing. Here, we use DNA methylation analysis to examine retrotransposons in mouse male germ cells.

Transposable Elements and Genome Size Variations in Plants [PDF]

Genomics & Informatics, 2014
Although the number of protein-coding genes is not highly variable between plant taxa, the DNA content in their genomes is highly variable, by as much as 2,056-fold from a 1C amount of 0.0648 pg to 132.5 pg.
