  • genomic islands

    hi all- is there a softwrae that is used to determine (genomic islands) within the draft assembled bacterial genomes?- thanks all

  • #2
    There are lots of approaches, often based on comparison to several close relatives to find novel genes not in the relatives. If these form clusters they are candidates for horizontally acquired islands - although if in a lone contig you might also suspect contamination.

      thanks- what is the fastest approach to determine unique genes (specially genomic islands) within the assembled draft genomes

        what is the software can tell about genomic islands (no. size, etc) in relation to the reference bacterial genome please?

          You'll just need to pick out differences manually. Use a visual genome aligner like Mauve to compare your genome against a reference. You can even get as simple as a straight up dotplot. Large genetic insertions should be blindingly obvious.

            Here is a review listing the methods to detect genomic islands http://www.nature.com/nrmicro/journa...micro2350.html

              Exploring the Dynamics of the Tumor Microenvironment
              by seqadmin




              The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

              Exploring Human Diversity Through Large-Scale Omics
              by seqadmin


              In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
