Large insert environmental genomic library production.
The vast majority of microbes in nature currently remain inaccessible to traditional cultivation methods. Over the past decade, culture-independent environmental genomic (i.e. metagenomic) approaches have emerged, enabling researchers to bridge this cultivation gap by capturing the genetic content of indigenous microbial communities directly from the environment. To this end, genomic DNA librar...
متن کاملTen polymorphic microsatellite loci identified from a small insert genomic library for Peronospora tabacina.
Ten polymorphic microsatellite loci for the obligate biotrophic, oomycete pathogen of tobacco, Peronospora tabacina, were identified from a small insert genomic library enriched for GT motifs. Eighty-five percent of the 162 loci identified were composed of dinucleotide repeats, whereas only 4% and 11% were tri-and tetra-nucleotide repeats respectively. About 82% of all the microsatellites were ...
متن کاملMetagenomic profiling: microarray analysis of an environmental genomic library.
Genomic libraries derived from environmental DNA (metagenomic libraries) are useful for characterizing uncultured microorganisms. However, conventional library-screening techniques permit characterization of relatively few environmental clones. Here we describe a novel approach for characterization of a metagenomic library by hybridizing the library with DNA from a set of groundwater isolates, ...
متن کاملLong-term stability of large insert genomic DNA episomal shuttle vectors in human cells.
We have constructed an episomal shuttle vector which can transfer large (>100 kb) human genomic DNA inserts back and forth between bacteria and human cells and which can be tracked in rapidly dividing human cells using a live cell assay. The vector (p5170) is based on the F factor-derived bacterial artificial chromosome cloning vector used in Escherichia coli, with the addition of the family of...
متن کاملDirect hybridization of large-insert genomic clones on high-density gridded cDNA filter arrays.
A major challenge to positional cloning approaches is the identification of coding sequences within a region of interest. Hybridization of genomic fragments that represent a cloned contig of a defined genomic region in appropriate cDNA libraries theoretically represents a direct solution to this problem. However, this is technically difficult and in general, success with this approach has been ...
