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 ...

Turning gold into 'junk': transposable elements utilize central proteins of cellular networks [PDF]
, 2013 The numerous discovered cases of domesticated transposable element (TE) proteins led to the recognition that TEs are a significant source of evolutionary innovation.

BMC Genomics, 2007 Background LTR retrotransposons are one of the main causes for plant genome size and structure evolution, along with polyploidy. The characterization of their amplification and subsequent elimination of the genomes is therefore a major goal in plant ...

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

Site-specific non-LTR retrotransposons
Microbiology Spectrum, 2015 ABSTRACT Although most of non-long terminal repeat (non-LTR) retrotransposons are incorporated in the host genome almost randomly, some non-LTR retrotransposons are incorporated into specific sequences within a target site. On the basis of structural and phylogenetic features, non-LTR retrotransposons are classified into two large groups ...

Activation of a LTR-retrotransposon by telomere erosion [PDF]
Proceedings of the National Academy of Sciences, 2003 Retrotransposons can facilitate repair of broken chromosomes, and therefore an important question is whether the host can activate retrotransposons in response to chromosomal lesions. Here we show that Ty1 elements, which are LTR-retrotransposons in Saccharomyces cerevisiae , are mobilized when DNA lesions are ...

The use of retrotransposon-based molecular markers to analyze genetic diversity [PDF]
, 2011 Molecular markers play an essential role in all aspects of genetics, modern plant breeding, in human forensics, for map-based cloning of genes, ranging from the identification of genes responsible for desired traits to the management of backcrossing ...

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives
Insect Science, EarlyView.The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...
