Comparative genomic analysis reveals species-dependent complexities that explain difficulties with microsatellite marker development in molluscs

Reliable population DNA molecular markers are difficult to develop for molluscs, the reasons for which are largely unknown. Identical protocols for microsatellite marker development were implemented in three gastropods. Success rates were lower for Gibbula cineraria compared to Littorina littorea and L. saxatilis. Comparative genomic analysis of 47.2?kb of microsatellite containing sequences (MCS) revealed a high incidence of cryptic repetitive DNA in their flanking regions. The majority of these were novel, and could be grouped into DNA families based upon sequence similarities. Significant inter-specific variation in abundance of cryptic repetitive DNA and DNA families was observed. Repbase scans show that a large proportion of cryptic repetitive DNA was identified as transposable elements (TEs). We argue that a large number of TEs and their transpositional activity may be linked to differential rates of DNA multiplication and recombination. This is likely to be an important factor explaining inter-specific variation in genome stability and hence microsatellite marker development success rates. Gastropods also differed significantly in the type of TEs classes (autonomous vs non-autonomous) observed. We propose that dissimilar transpositional mechanisms differentiate the TE classes in terms of their propensity for transposition, fixation and/or silencing. Consequently, the phylogenetic conservation of non-autonomous TEs, such as CvA, suggests that dispersal of these elements may have behaved as microsatellite-inducing elements. Results seem to indicate that, compared to autonomous, non-autonomous TEs maybe have a more active role in genome rearrangement processes. The implications of the findings for genomic rearrangement, stability and marker development are discussed.

‘‘Capital of Culture - you must be having a laugh!” Challenging the official rhetoric of Liverpool as the 2008 European cultural capital’

Major cultural events are increasingly seen by local stakeholders as important opportunities to stimulate urban regeneration, city branding and economic development. The European Capital of Culture programme is a prominent example. Since 1985 over thirty cities have hosted the title and today it remains a highly sought-after prize. This paper analyses competing interpretations of the success of Liverpool's hosting of the European Capital of Culture in 2008. It unpacks contrasting views of Liverpool08, from the official triumphant message of urban regeneration and economic renaissance to more critical analyses that problematise important elements of the event and its social and spatial impacts. In so doing, it challenges the hyperbole of culture-led transformation to reveal different geographies of culture, different cultural experiences and different socio-economic realities; it also offers an additional cultural reading of Liverpool in 2008. Through the example of Liverpool this paper shows how local culture is politicised, manipulated and sanitised in order to stimulate urban regeneration and construct a spatial re-branding of the city.

De grands événements culturels sont de plus en plus perçus par les rentiers locaux comme des opportunités importantes pour stimuler la régénération urbaine, produire la devise des villes et le développement économique. L'initiative La Capitale Européenne de la Culture est un exemple proéminent. Depuis 1985, plus de trente villes ont accueilli le titre et maintenant il reste un prix largement recherché. Cet article analyse des interprétations en concurrence du succès de l'accueil de Liverpool de la Capitale Européenne de la Culture en 2008. Il déballe des vues contrastées de Liverpool08, du message officiel et triomphal de la régénération urbaine et de la renaissance économique à des analyses plus critiques qui problématisent des éléments importants de l'événement et ses impacts sociaux et spatiaux. De cette façon, il conteste l'hyperbole de la transformation menée par la culture pour révéler des géographies différentes de la culture, des expériences différentes de la culture et des réalités socioéconomiques différentes; il offre aussi une interprétation culturelle différente de Liverpool en 2008. Au travers de l'exemple de Liverpool cet article montre comment la culture locale est politisée, manipulée et aseptisée pour stimuler la régénération urbaine et construire un relookage spatial de la ville.

Cada vez más, los inversores locales vean a los eventos culturales como oportunidades importantes para estimular regeneración urbana, el desarollo económico y la branding a una ciudad. El Capital Europeo de Cultura es un ejemplo prominente. Desde 1985, más que treinta ciudades han presentado el título y hoy sigue siendo un premio deseable. Este papel se analiza interpretaciones competitivos del éxito del Capital Europea de Cultura 2008 en Liverpool. Se deshace las perspectivas opuestas del Liverpool08, del mensaje triunfante de regeneración urbana y renacimiento económico, a analices críticos que problematizan elementos importantes del evento y sus impactos sociales y espaciales. Al hacer esto, se cuestiona el hipérbole de la transformación cultural para revelar geografías diferentes de cultura, experiencias culturales diferentes y realidades diferentes socio-económicas; también ofrece un entendimiento cultural adicional de Liverpool en el 2008. Através el ejemplo de Liverpool, este papel demuestra como la cultura local está politizada, manipulada, y desinfectado para estimular regeneración urbana y construir una nueva branding de la ciudad.

Characterization of IS2112, a new insertion sequence from Rhodococcus, and its relationship with mobile elements belonging to the IS110 family

A new insertion sequence (IS2112) was identified in the genome of the 1-haloalkane-utilizing bacterium Rhodococcus rhodochrous NCIMB 13064. The insertion element is 1415 bp long, does not contain terminal inverted repeats, and is not flanked by directly repeated sequences. IS2112 belongs to the IS110 family of transposable elements, and forms a separate subfamily, along with IS116, Two copies of IS2112 were found in R, rhodochrous NCIMB 13064 and one, two or three copies of a similar sequence were detected in five other 1-haloalkane-degrading Rhodococcus strains. There were no sequences homologous to IS2112 found in the l-haloalkane-degrading 'Pseudomonas pavonaceae' 170 and Rhodococcus sp, HA1 or in several Rhodococcus strains which do not utilize haloalkanes, IS2112 was originally found in plasmid pRTL1 of R. rhodochrous NCIMB 13064 which harbours genes encoding utilization of l-haloalkanes, and was located 5 kbp upstream of the haloalkane dehalogenase gene (dhaA), Although the second copy of IS2112 in strain NCIMB 13064 was also present on the pRTL1 plasmid, these sequences do not apparently comprise a single composite transposon encoding haloalkane utilization. An analysis of derivatives of NCIMB 13064 revealed that IS2112 was involved in genome rearrangements. IS2112 appeared to change its location as a result of transposition and as a result of other rearrangements of the NCIMB 13064 genome.

Frequency and distribution of group I intron genotypes of Candida albicans colonising critically ill patients

A study is performed to examine the distribution and frequency of 25S rRNA intron genotypes of Candida albicans isolated from different anatomical sites of patients in an intensive care unit (ICU) setting. Germ-tube positive Candida isolates (n=65) from 65 patients are included and isolates are characterised by 25S intron genotyping, whereby all can be subdivided into four genotypes (A-D). Results demonstrated that there were no significant differences between the frequency and genotype distribution of the Candida isolates and the anatomical site of colonisation. Furthermore, analysis of the transposable intron region in the 25S rRNA gene demonstrated equal distribution, regardless of age and anatomical site of isolation (groin, throat, etc.). Therefore, there does not appear to be any selective pressure associated with any anatomical site, resulting in an ecological shift in the frequency of genotypes present. This suggests that C. albicans intron genotypes equally colonise those sites of the body examined in this study. Although such an ecological finding as this is interesting, it perpetuates the continued need to find a genotypic typing scheme that helps to identify the source (nosocomial or endogenous) and mode of entry of C. albicans into patients in the ICU setting, resulting in C. albicans bloodstream infection.

Trait directed de novo population transcriptome dissects genetic regulation of a balanced polymorphism in phosphorus nutrition/arsenate tolerance in a wild grass Holcus lanatus

The aim of this study was to characterize the transcriptome of a balanced polymorphism, under the regulation of a single gene, for phosphate fertilizer responsiveness/arsenate toler- ance in wild grass Holcus lanatus genotypes screened from the same habitat.

De novo transcriptome sequencing, RNAseq (RNA sequencing) and single nucleotide poly- morphism (SNP) calling were conducted on RNA extracted from H.lanatus. Roche 454 sequencing data were assembled into c. 22 000 isotigs, and paired-end Illumina reads for phosphorus-starved (P) and phosphorus-treated (P+) genovars of tolerant (T) and nontoler- ant (N) phenotypes were mapped to this reference transcriptome.

Heatmaps of the gene expression data showed strong clustering of each P+/P treated genovar, as well as clustering by N/T phenotype. Statistical analysis identified 87 isotigs to be significantly differentially expressed between N and T phenotypes and 258 between P+ and P treated plants. SNPs and transcript expression that systematically differed between N and T phenotypes had regulatory function, namely proteases, kinases and ribonuclear RNA- binding protein and transposable elements.

A single gene for arsenate tolerance led to distinct phenotype transcriptomes and SNP pro- files, with large differences in upstream post-translational and post-transcriptional regulatory genes rather than in genes directly involved in P nutrition transport and metabolism per se.

Independent genomewide screens identify the tumor suppressor VTRNA2-1 as a human epiallele responsive to periconceptional environment

Background: Interindividual epigenetic variation that occurs systemically must be established prior to gastrulation in the very early embryo and, because it is systemic, can be assessed in easily biopsiable tissues. We employ two independent genome-wide approaches to search for such variants.

Results: First, we screen for metastable epialleles by performing genomewide bisulfite sequencing in peripheral blood lymphocyte (PBL) and hair follicle DNA from two Caucasian adults. Second, we conduct a genomewide screen for genomic regions at which PBL DNA methylation is affected by season of conception in rural Gambia. Remarkably, both approaches identify the genomically imprinted VTRNA2-1 as a top environmentally responsive epiallele. We demonstrate systemic and stochastic interindividual variation in DNA methylation at the VTRNA2-1 differentially methylated region in healthy Caucasian and Asian adults and show, in rural Gambians, that periconceptional environment affects offspring VTRNA2-1 epigenotype, which is stable over at least 10 years. This unbiased screen also identifies over 100 additional candidate metastable epialleles, and shows that these are associated with cis genomic features including transposable elements.

Conclusions: The non-coding VTRNA2-1 transcript (also called nc886) is a putative tumor suppressor and modulator of innate immunity. Thus, these data indicating environmentally induced loss of imprinting at VTRNA2-1 constitute a plausible causal pathway linking early embryonic environment, epigenetic alteration, and human disease. More broadly, the list of candidate metastable epialleles provides a resource for future studies of epigenetic variation and human disease.
