Processing of insect retrotransposons by self-cleaving ribozymes [PDF]
, 2010 We show that several classes of insect non-LTR retrotransposons harbor self-cleaving ribozymes of the HDV family at their 5′ termini. In Drosophila the R2 ribozymes exhibit highly differential in vivo expression and robust in vitro activity ...

Waves of genomic hitchhikers shed light on the evolution of gamebirds (Aves: Galliformes) : research article [PDF]
, 2007 Background The phylogenetic tree of Galliformes (gamebirds, including megapodes, currassows, guinea fowl, New and Old World quails, chicken, pheasants, grouse, and turkeys) has been considerably remodeled over the last decades as new data and analytical ...

Mobile genetic elements – mechanism and consequences of transposition
Journal of Education, Health and Sport, 2017 Retrotransposons represent a significant part of the genome in eukaryote organisms. With DNA transposons, they belong to mobile genetic elements. There are two classes of transposons, DNA transposons and retrotransposons.

Plant Biotechnology Journal, EarlyView.ABSTRACT Anthocyanins are plant pigments that contribute to fruit coloration and nutritional quality, yet the coordinated regulation of their accumulation in both peel and flesh remains elusive. Here, we present a haplotype‐resolved genome of Malus cv. ‘Royalty’, a model cultivar with consistently red peel and flesh. A zinc‐finger transcription factor,

Mobile DNAPlant genomes include large numbers of transposable elements. One particular type of these elements is flanked by two Long Terminal Repeats (LTRs) and can translocate using RNA.

BMC Genomics, 2005 Background It is becoming apparent that perhaps as much as half of the genome of the human blood fluke Schistosoma mansoni is constituted of mobile genetic element-related sequences.

Ancient Origin of the U2 Small Nuclear RNA Gene-Targeting Non-LTR Retrotransposons Utopia. [PDF]
PLoS ONE, 2015 Most non-long terminal repeat (non-LTR) retrotransposons encoding a restriction-like endonuclease show target-specific integration into repetitive sequences such as ribosomal RNA genes and microsatellites.

Weak Effect of Gypsy Retrotransposon Bursts on Sonneratia alba Salt Stress Gene Expression
Frontiers in Plant Science, 2022 Transposable elements (TEs) are an important source of genetic diversity and can be co-opted for the regulation of host genes. However, to what extent the pervasive TE colonization of plant genomes has contributed to stress adaptation remains ...

Transposable Element‐Mediated Structural Variation Drives Flower Colour Diversification in Camellia
Plant Biotechnology Journal, EarlyView.ABSTRACT The role of transposable elements (TEs) in genome evolution and phenotypic diversification in Camellia remains poorly understood. Here, we present an integrated analysis of genome resequencing data from 237 Camellia accessions and 11 de novo genome assemblies representing all major floral colour types.

Transposable elements: How non-LTR retrotransposons do it [PDF]
Current Biology, 1997 The source of the enzyme activity responsible for the transposition of retrotransposons of the type that lack terminal repeats has at last been identified: in L1Hs elements, it is encoded by the second open reading frame and is a nuclease related to the apurinic repair endonucleases.
