Clone-array pooled shotgun mapping and sequencing: design and analysis of experiments.
نویسندگان
چکیده
This paper studies sequencing and mapping methods that rely solely on pooling and shotgun sequencing of clones. First, we scrutinize and improve the recently proposed Clone-Array Pooled Shotgun Sequencing (CAPSS) method, which delivers a BAC-linked assembly of a whole genome sequence. Secondly, we introduce a novel physical mapping method, called Clone-Array Pooled Shotgun Mapping (CAPS-MAP), which computes the physical ordering of BACs in a random library. Both CAPSS and CAPS-MAP construct subclone libraries from pooled genomic BAC clones.

Pooled Genomic Indexing (PGI): Analysis and Design of Experiments
Pooled Genomic Indexing (PGI) is a novel method for physical mapping of clones onto known sequences. PGI is carried out by pooling arrayed clones and generating shotgun sequence reads from the pools. The shotgun sequences are compared to a reference sequence. In the simplest case, clones are placed on an array and are pooled by rows and columns. If a shotgun sequence from a row pool and another...
متن کاملA clone-array pooled shotgun strategy for sequencing large genomes.
A simplified strategy for sequencing large genomes is proposed. Clone-Array Pooled Shotgun Sequencing (CAPSS) is based on pooling rows and columns of arrayed genomic clones, for shotgun library construction. Random sequences are accumulated, and the data are processed by sequential comparison of rows and columns to assemble the sequence of clones at points of intersection. Compared with either ...
متن کاملFine-mapping of shotgun template-libraries; an efficient strategy for the systematic sequencing of genomic DNA.
To test the effectiveness of ordering shotgun DNA-templates prior to sequence analysis, the 450 kb left arm of yeast chromosome XII was randomly subcloned into a phagemid vector. Clones were ordered by hybridisation to an average map density of one new insert every 125 bp and are currently used for sequencing the chromosomal fragment. An 11.5 kb overlap between the template map and a DNA fragme...
متن کاملA sequence-ready physical map of barley anchored genetically by two million single-nucleotide polymorphisms.
Barley (Hordeum vulgare) is an important cereal crop and a model species for Triticeae genomics. To lay the foundation for hierarchical map-based sequencing, a genome-wide physical map of its large and complex 5.1 billion-bp genome was constructed by high-information content fingerprinting of almost 600,000 bacterial artificial chromosomes representing 14-fold haploid genome coverage. The resul...
متن کاملOptimal clone identifier for genomic shotgun libraries: "OC Identifier tool".
In DNA microarray experiments, the gene fragments that are spotted on the slides are usually obtained by the synthesis of specific oligonucleotides that are able to amplify genes through PCR. Shotgun library sequences are an alternative to synthesis of primers for the study of each gene in the genome. The possibility of putting thousands of gene sequences into a single slide allows the use of s...
