Genetic relatedness of the family Rhodospirillaceae: Genome plasticity, chromosome heterogeneity, and chalcogenic oxyanion reductase activity in Rhodobacter sphaeroides
"Intrinsic high-level resistance (HLR) to tellurite (TeO$\sb3\sp{2-}),$ selenite (SeO$\sb3\sp{2-}),$ and at least fifteen other chalcogenic oxides and oxyanions has been demonstrated in the facultative photoheterotrophic bacterium, Rhodobacter (Rba.) sphaeroides. Detailed analyses have shown that …

Repetitive Sequences Drive Rapid Adaptation in Candida albicans
Genome plasticity is commonly observed during speciation, the somatic evolution of cancer, and during the rapid adaptation of fungi to novel environments. In the human fungal pathogen Candida albicans, genome plasticity resulting in copy number variations (CNVs) and loss of heterozygosity (LOH) …

Mammalian-wide interspersed repeats (MIRs) and their role in mammalian gene function and evolution
… are ubiquitous components of plant and animal genomes and constitute more than ~45% of the human genome. Though originally considered as 'parasitic' or 'junk' DNA, TEs are now thought to have played a role in shaping genomes during evolution, contributing to genome plasticity and diversity. All …

Functional Genomics of Stress Response in the Hyperthermophilic Crenarchaeon Sufolobus solfataricus and Role of vapBC Toxin-Antitoxin Loci in RNA Management.
… to growth under normal conditions. Whole genome oligonucleotide microarray analyses revealed substantial transcriptional changes in this crenarcheon upon temperature shifts from 80 to 90°C at pH 4.0, and pH shifts from 4.0 to 2.0 at 80°C. ORFs encoding heat shock proteins, molecular …

Studies on the architecture and on transferability of pathogenicity islands of uropathogenic Escherichia coli strain 536
… the sequence determination of complete bacterial genomes started a new era in microbiological research. Since then more than two hundred prokaryotic and eukaryotic genomes have been completely sequenced, and there are additional complete genome projects including different bacterial species and …

Identification and characterisation of lactic acid bacterial secondary metabolites with functional and health benefits
… seven subgroups. Members of the SBSEC show high genome plasticity and in Chapter Six the bacteriocin capabilities of the complex were further examined by including all sequenced strains from each subgroup. The genomes of 105 strains were downloaded and analysed using Bagel4 to identify potential …

Molecular dissection of competence regulated virulence in Streptococcus pneumoniae
… for recombination. In addition to improving genome plasticity, a natural competence system directly contributes to pneumococcal virulence during pneumonia and bacteremia, independent of DNA uptake. Competence is activated when the competence stimulating peptide (CSP), encoded by the comC …

Untersuchungen zur Instabilität von Pathogenitätsinseln des uropathogenen Escherichia coli Stammes 536 : "Island Probing" von PAI I(536) - PAI V(536)
Der uropathogene Escherichia coli Stamm 536 (O6:K15:H31) stammt aus einem Patienten mit akuter Pyelonephritis und ist heute einer der Hauptmodellorganismen für Studien zum Vorkommen und zur Funktionalität von Pathogenitätsinseln (PAIs). Sein Genom enthält sechs genetische Elemente (PAI I(536) bis …
