MERE1, 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 کاملCopy Number of the Transposon, Pokey, in rDNA Is Positively Correlated with rDNA Copy Number in Daphnia obtusa
Pokey is a class II DNA transposon that inserts into 28S ribosomal RNA (rRNA) genes and other genomic regions of species in the subgenus, Daphnia. Two divergent lineages, PokeyA and PokeyB have been identified. Recombination between misaligned rRNA genes changes their number and the number of Pokey elements. We used quantitative PCR (qPCR) to estimate rRNA gene and Pokey number in isolates from...

متن کاملSequence evolution and copy number of Ty1-copia retrotransposons in diverse plant genomes.
Sequence evolution of the reverse transcriptase (RT) gene in retrotransposons belonging to the Ty1-copia class was studied in 11 plant species. Phylogenetic reconstruction of the evolutionary history of RT sequences indicated a strong pattern of purifying selection, manifested as high ratios of third to first plus second codon position substitutions, and low ratios of nonsynonymous substitution...
متن کاملA high-copy-number CACTA family transposon in temperate grasses and cereals.
A lineage of CACTA family transposons has been identified in temperate grasses and cereals, and a full-length representative of the subfamily from Lolium perenne has been sequenced. Both the size and internal organization of the L. perenne element are typical of other CACTA family elements but its high copy number and strong conservation are unexpected. Comparison with homologs in other species...
