Summary Microsatellites are currently considered the most useful genetic markers with wide applications in genomics, quantitative and population genetics. We present here structure of core sequence 552 microsatellites, together sequences primers length sequenced allele. These microsatellites were isolated from several libraries constructed either fractions total genomic DNA or clones a bacterial artificial chromosome (BAC) library. All loci polymorphic honeybee. Many them also successfully...
The first draft of the honey bee genome sequence and improved genetic maps are utilized to analyze a displaying 10 times higher levels recombination (19 cM/Mb) than previously analyzed genomes eukaryotes. exceptionally high rate is distributed genome-wide, but varies by two orders magnitude. Analysis chromosome, sequence, gene parameters with respect showed that local associated distance telomere, GC content, number simple repeats as described for low-recombining genomes. Recombination does...
The honey bee is a key model for social behavior and this feature led to the selection of species genome sequencing. A genetic map necessary companion sequence. In addition, because there was originally no physical project, meiotic only resource organizing sequence assembly on chromosomes.We present (meiotic) here describe main features that emerged from comparison with sequence-based map. saturated chromosomes are oriented centromeric telomeric regions. based 2,008 markers about 40 Morgans...
Contrary to native predators, which have co-evolved with their prey, alien predators often benefit from prey naïveté. Vespa velutina, a honeybee predator originating Eastern China, was introduced into France just before 2004. The present study, based on video recordings of two beehives at an early stage the invasion process, intends analyse hornet hunting behaviour Apis mellifera, and understand interaction between activity during day season. Chasing hornets spent most time hovering facing...
Abstract While workers of almost all subspecies honeybee are able to lay only haploid male eggs, Apis mellifera capensis produce diploid female eggs by thelytokous parthenogenesis. Cytological analyses have shown that during parthenogenesis, egg diploidy is restored fusion the two central meiotic products. This peculiarity Cape bee preserves products a single meiosis in daughters and can be used map centromere positions using half-tetrad analysis. In this study, we use progenies A. m. sample...
In Latin America, the bloodsucking bugs Triatominae are vectors of Trypanosoma cruzi, parasite that causes Chagas disease. Chemical elimination programs have been launched to control disease vectors. However, persists because native from sylvatic habitats able (re)colonize houses-a process called domiciliation. Triatoma brasiliensis is one example. Because chemosensory system allows insects interact with their environment and plays a key role in insect adaption, we conducted descriptive...
Previous analysis of mitochondrial DNA polymorphism in the native range European rabbit (Oryctolagus cuniculus) demonstrated occurrence two highly divergent (2 Myr) maternal lineages with a well-defined geographical distribution. Analysis both protein and immunoglobulin polymorphisms are concordant this pattern differentiation. However, present nine polymorphic microsatellite loci (with total 169 alleles) 24 wild populations reveals severe allele-size homoplasy which vastly underestimates...
Abstract A linkage map for the honeybee (Apis mellifera) was constructed mainly from progeny of two hybrid queens (A. m. ligustica × A. mellifera). total 541 loci were mapped; 474 microsatellite loci; a few additional bands produced during PCRs, one rDNA (using ITS), MDH locus, and three sex-linked markers (Q FB RAPD band). Twenty-four groups estimated which 5 minute (between 7.1 22.8 cM) 19 major (>76.5 cM). The number exceeded by chromosomes complement (n = 16). sum lengths all...
Abstract Honeybee subspecies have been affected by human activities in Europe over the past few decades. One such example is importation of nonlocal bees which has had an adverse impact on geographical repartition and subsequently genetic diversity black honeybee A pis mellifera . To restore original this local subspecies, different conservation centres were set up Europe. In study, we established a centre Conservatoire de l'Abeille Noire d'Ile France ( CANIF ) region Ile‐de‐France, France....
Infectious diseases and their demographic consequences are thought to influence the genetic diversity of populations. In Europe, during last 50 years, European rabbit (Oryctolagus cuniculus) has suffered two important viral epizootics: myxomatosis haemorraghic disease (RVHD). Although mortality rates were very high, impact these on never been assessed directly. The subject this paper is a wild population in France, which studied since beginning 1980s. first outbreak RVHD occurred 1995...
We provide in this study a very large DNA dataset on Rhodnius species including 36 samples representing 16 valid of the three groups, pictipes, prolixus and pallescens. Samples were sequenced at low-depth with whole-genome shotgun sequencing (Illumina technology). Using phylogenomics 15 mitochondrial genes (13.3 kb), partial nuclear rDNA (5.2 kb) 51 protein-coding (36.3 we resolve sticking points phylogeny. At level, confirmed species-specific status R. montenegrensis marabaensis agree...
Background Meiotic exchanges are non-uniformly distributed across the genome of most studied organisms. This uneven distribution suggests that recombination is initiated by specific signals and/or regulations. Some these were recently identified in humans and mice. However, it unclear whether or not sequence also involved chromosomal insects. Methodology We analyzed frequencies honeybee, which sequencing provided a large amount SNPs spread over entire set chromosomes. As sequences obtained...

Two strains of the endoparasitoid Cotesia typhae (Hymenoptera: Braconidae) present a differential parasitism success on host, Sesamia nonagrioides (Lepidoptera: Noctuidae). One is virulent both permissive and resistant host populations, other only host. This interaction provides very interesting frame for studying virulence factors. Here, we used combination comparative transcriptomic proteomic analyses to unravel molecular basis underlying differences between strains.
