    1. How big is the Burkholderia cenocepacia genome?

      Our current total unique contig length is 6,927,835 bp (base pairs). The estimated genome size of B. cenocepacia is 7.5 Mb.

    2. What strain was sequenced?

      Burkholderia cenocepacia strain AUO158.

    3. What is the current state of the assembly?

      The current assembly contains 174 sequence contigs in 3 supercontigs (scaffolds). There are no current plans for additional sequencing or finishing. See Assembly for detail.

    4. How has the sequence been generated for the Burkholderia cenocepacia project?

      Our data consist of over 120,000 individual sequencing reads obtained by sequencing each end of plasmids and Fosmids from libraries containing randomly sheared fragments of 4 kb, 10 kb, and 40 kb average size respectively. See Assembly for details.

    5. Will the genome be finished?

      Unfortunately there are no plans to finish this genome at this time.

    6. How will we know the assembly is correct?

      The quality of the assembly will be assessed in several ways. In addition to requiring that the paired plasmid and Fosmid ends occur in a logical manner, our assembly of the Burkholderia cenocepacia genome will be verified through comparison with available genomic sequences.

    7. What data are available?

      In this version of our data release, all sequence contigs and supercontigs are available. Sequence data can be accessed in several ways: either through a searching with BLASTN or TBLASTN, retrieving of a specific region of the assembly, or by downloading the entire genome. Supercontig and contig sequences are subject to change throughout this project, so each data release version number will be appended to the contig number as a prefix (e.g. 1.1 denotes assembly version 1, supercontig #1).

      Fosmid clones have been integrated into the current assembly, and you can search and view the locations of these clones within the sequence supercontigs.

      A fasta file of raw reads excluded from the assembly is also available for BLAST and download. Also available for download are an AGP file describing the supercontigs and contigs in this assembly and a file listing coordinates of paired endreads.

    8. This sequence release looks different from previous releases, like Neurospora crassa. What's different?

      Important information about this release can be found here.

  • Misc
    1. How do I cite the sequence for publication?

      Publications should include the following citation:
      Burkholderia cenocepacia Sequencing Project. Broad Institute of Harvard and MIT (http://www.broad.mit.edu)

    2. Who do I contact with questions about the sequencing?

      Our email address is annotation-webmaster@broad.mit.edu.

    3. Who provided the photos in this website?

      The photos 1-3 are electron micrographs of Burkholderia colonizing the pea rhizosphere. They were kindly provided by Amanda Fivian, Louise O'Sullivan and Eshwar Mahenthiralingam, from Cardiff School of Biosciences, Cardiff University, Wales, UK.
