High-Density Transcriptional Initiation Signals Underline Genomic Islands in Bacteria
Genomic islands (GIs), frequently associated with the pathogenicity of bacteria and having a substantial influence on bacterial evolution, are groups of "alien" elements which probably undergo special temporal-spatial regulation in the host genome. Are there particular hallmark transcriptional signals for these "exotic" regions? We here explore the potential transcriptional signals that underli...
متن کاملComparative genomic reconstruction of transcriptional regulatory networks in bacteria.
Microorganisms in most ecological niches are constantly exposed to variations of many environmental factors, including temperature; oxygen, nutrient, and water availability; presence of toxic compounds; and interaction with other organisms. Changing gene-expression patterns is a major adaptive response to these variations. Expression of genes in bacteria is controlled by a variety of mechanisms...
متن کاملGenomic islands of speciation or genomic islands and speciation?
Populations of the malaria mosquito, Anopheles gambiae, are comprised of at least two reproductively isolated, sympatric populations. In this issue, White et al. (2010) use extensive sampling, high-density tiling microarrays, and an updated reference genome to clarify and expand our knowledge of genomic differentiation between these populations. It is now clear that DNA near the centromeres of ...
متن کاملPredicting CpG Islands and Their Relationship with Genomic Feature in Cattle by Hidden Markov Model Algorithm
Cattle supply an important source of nutrition for humans in the world. CpG islands (CGIs) are very important and useful, as they carry functionally relevant epigenetic loci for whole genome studies. As a matter of fact, there have been no formal analyses of CGIs at the DNA sequence level in cattle genomes and therefore this study was carried out to fill the gap. We used hidden markov model alg...
متن کاملTransposon Tn7 is widespread in diverse bacteria and forms genomic islands.
We find that relatives of the bacterial transposon Tn7 are widespread in disparate environments and phylogenetically diverse species. These elements form functionally diverse genomic islands at the specific site of Tn7 insertion adjacent to glmS. This work presents the first example of genomic island formation by a DDE type transposon.
