Identification of potential transcriptionally active Copia LTR retrotransposons in Eucalyptus
Background Long Terminal Repeat retrotransposons (LTR-RTs) represent the most abundant genomic component in all plant genomes thus far investigated. They are transposable elements that replicate through a “copy/paste” mechanism that relies on reverse transcription and integration of a RNA intermediate. Plant LTR-RTs can be divided in two major superfamilies: Copia and Gypsy[1]. LTR-RTs have imp...
متن کاملSIRE-1, a copia/Ty1-like retroelement from soybean, encodes a retroviral envelope-like protein.
The soybean genome hosts a family of several hundred, relatively homogeneous copies of a large, copia/Ty1-like retroelement designated SIRE-1. A copy of this element has been recovered from a Glycine max genomic library. DNA sequence analysis of two SIRE-1 subclones revealed that SIRE-1 contains a long, uninterrupted, ORF between the 3' end of the pol ORF and the 3' long terminal repeat (LTR), ...
متن کاملMERE1, a low-copy-number copia-type retroelement in Medicago truncatula active during tissue culture.
We have identified an active Medicago truncatula copia-like retroelement called Medicago RetroElement1-1 (MERE1-1) as an insertion in the symbiotic NSP2 gene. MERE1-1 belongs to a low-copy-number family in the sequenced Medicago genome. These copies are highly related, but only three of them have a complete coding region and polymorphism exists between the long terminal repeats of these differe...
متن کاملEARE-1, a Transcriptionally Active Ty1/Copia-Like Retrotransposon Has Colonized the Genome of Excoecaria agallocha through Horizontal Transfer
Long terminal repeat (LTR) retrotransposons constitute the majority of the content of angiosperm genomes, but their evolutionary dynamics remain poorly understood. Here, we report the isolation and characterization of a putative full-length (~9550 bp) Ty1/copia-like retrotransposon in Excoecaria agallocha and its evolution in Euphorbiaceae. The so-called EARE-1 is phylogenetically closely relat...
متن کاملCopia is transcriptionally responsive to environmental stress.
Adult Drosophila subjected to a variety of environmental stresses that induce classic Drosophila heat shock response simultaneously exhibit a rapid and significant rise in copia homologous transcripts. Levels of Drosophila Adh (alcohol dehydrogenase gene) and 18s ribosomal RNA were unaffected by environmental stress. Copia's ability to be induced by stress is correlated with the presence of seq...
