“…Thus, we recommend that the original classifi cation should be broadened to include the irritans elements characterized in this study, as well as the two irritans elements Tvmar1 (Claudianos et al, 2002) and Pacmmar1 (Bui et al, 2007), which also differ from the four known irritans lineages.…”

“…Eluted DNA was then cloned in pGEM-T Vector System (Promega), according to the Manufacturer's protocol. E. coli DH5a cells (New England Biolabs) were transformed and selected as described by Bui et al (2007). Positive clones were screened during a subsequent PCR using T7 and SP6 primers.…”

“…This 1,286-bp element, initially designated pch, includes a single open reading frame encoding a protein of 345 amino acids with TIRs of 28 bp at each extremity (Jacobson et al 1986). Since then, numerous mariner elements have been characterized in nematodes (Leroy et al 2003), crustaceans (Casse et al 2006;Bui et al 2007Bui et al , 2008, fish (Ivics et al 1997), human beings (Augé-Gouillou et al 1995;Robertson and Zumpano 1997;Robertson and Martos 1997), plants (Casacuberta et al 1998;Feschotte and Wessler 2002;Zhou et al 2010), protozoans (Silva et al 2005), and insects (Robertson 1993;Robertson and McLeod 1993;Rouleux-Bonnin et al 2005;Wang et al 2011;Rezende-Teixeira et al 2012).…”

Mariner-like elements (MLEs) are Class II transposons present in all eukaryotic genomes in which MLEs have been searched for. This article reports the detection of MLEs in seven of the main fruit tree aphid species out of eight species studied. Deleted MLE sequences of 916-919 bp were characterized, using the terminal-inverted repeats (TIRs) of mariner elements belonging to the mauritiana Subfamily as primers. All the sequences detected were deleted copies of full-length elements that included the 3'- and 5'-TIRs but displayed internal deletions affecting Mos1 activity. Networks based on the mtDNA cytochrome oxidase subunit-I (CO-I) and MLE sequences were incongruent, suggesting that mutations in transposon sequences had accumulated before speciation of tree aphid species occurred, and that they have been maintained in this species via vertical transmissions. This is the first evidence of the widespread occurrence of MLEs in aphids.

“…To date, only a few TEs have been described in crustacean species: retroposon R2 in an isopod and in horseshoe crab , transposon Pokey from the piggyBac superfamily in a waterXea (Penton et al 2002) and marinerlike transposons (Casse et al 2000(Casse et al , 2006Kvamme et al 2005;Bui et al 2007), jockey-like and CR1-like retroposons (Halaimia-Toumi et al 2004) in hydrothermal and coastal crabs. No LTR retrotransposon has been described to date.…”

GalEa retrotransposons from galatheid squat lobsters (Decapoda, Anomura) define a new clade of Ty1/copia-like elements restricted to aquatic species

Crustacean species have not been examined in great detail for their transposable elements content. Here we focus on galatheid crabs, which are one of the most diverse and widespread taxonomic groups of Decapoda. Ty1/copia retrotransposons are a diverse and taxonomically dispersed group. Using degenerate primers, we isolated several DNA fragments that show homology with Ty1/copia retroelements reverse transcriptase gene. We named the corresponding elements from which they originated GalEa1 to GalEa3 and analyzed one of them further by isolating various clones containing segments of GalEa1. This is the first LTR retrotransposon described in crustacean genome. Nucleotide sequencing of the clones revealed that GalEa1 has LTRs (124 bp) and that the internal sequence (4,421 bp) includes a single large ORF containing gag and pol regions. Further screening identified highly related elements in six of the nine galatheid species studied. By performing BLAST searches on genome databases, we could also identify GalEa-like elements in some fishes and Urochordata genomes. These elements define a new clade of Ty1/copia retrotransposons that differs from all other Ty1/copia elements and that seems to be restricted to aquatic species.
