Satellite DNA in insects: a review
The study of insect satellite DNAs (satDNAs) indicates the evolutionary conservation of certain features despite their sequence heterogeneity. Such features can include total length, monomer length,Expand
Karyotype evolution in ants (Hymenoptera: Formicidae), with a review of the known ant chromosome numbers
Ants (Hymenoptera: Formicidae) constitute a diversified insect group with more than 12,000 species described. Like other hymenopterans, they are haplodiploid whereby fertilized eggs develop intoExpand
Chromosome numbers and karyotype evolution in holoparasitic Orobanche (Orobanchaceae) and related genera.
TLDR
Chromosome numbers and karyotypes of species of Orobanche, Cistanche, and Diphelypaea (Orobanchaceae) were investigated, and 108 chromosome counts of 53 taxa are presented with a thorough compilation of previously published data. Expand
Transposition of Mboumar-9: Identification of a New Naturally Active mariner-Family Transposon
TLDR
The Mboumar-9 transposase is expressed and purified and it is demonstrated that it is able to catalyze the movement of a transposon from one plasmid to another in a genetic in vitro hop assay and the efficiency is comparable to that of the well-characterized marinertransposon Mos1. Expand
Concerted evolution, a slow process for ant satellite DNA: study of the satellite DNA in the Aphaenogaster genus (Hymenoptera, Formicidae)
TLDR
The accumulated data suggest that evolution of satellite DNA in ants follows the concerted evolution pattern but that this process is slow in relation with other organisms, probably due to the eusociality and haplodiploidy of these insects. Expand
The presence of the ancestral insect telomeric motif in kissing bugs (Triatominae) rules out the hypothesis of its loss in evolutionarily advanced Heteroptera (Cimicomorpha)
TLDR
Next-generation sequencing data analysis on Triatoma infestans Klug, 1834 revealed the presence of the ancestral insect (TTAGG)n telomeric motif in its genome, contradicting the currently accepted hypothesis that evolutionarily recent heteropterans lack this ancestral insect telomersic sequence.

Analysis of the nucleolar organizing regions in the ant Tapinoma nigerrimum (Hymenoptera, Formicidae)
TLDR
This study analyses the NORs of Tapinoma nigerrimum by a combination of three methods: silver nitrate staining, in situ hybridization with fluorescein- or digoxigenin-labelled probes, and staining with the CG-specific fluorochrome chromomycin A3. Expand
Evolutionary dynamics of satellite DNA in species of the Genus Formica (Hymenoptera, Formicidae).
TLDR
It is suggested that, although the evolution of the DNA satellite in ants could be similar to that in other organisms, there may be some particularities as a result of a haplodiploid system. Expand
Plasma renin–angiotensin system-regulating aminopeptidase activities are modified in early stage Alzheimer's disease and show gender differences but are not related to apolipoprotein E genotype
TLDR
It is concluded that several components of the RAS are modified in AD patients, with gender differences, and ROC analysis indicates that APN, APB and IRAP activities could be useful non-invasive biomarkers of AD from the earliest stages. Expand
Conservation of (TTAGG)(n) telomeric sequences among ants (Hymenoptera, Formicidae).
TLDR
The TTAGG repeat seems to be the major component of the telomere sequence in the majority of ant species, as well as a strong hybridization signal even under highly stringent conditions. Expand
