By using the Illumina sequencing platform, we were able to obtain profiles from unselected tissues at much greater depth, allowing us to conduct the most thorough analysis of background insertion profiles to date.
In agreement with results described by Kato et al. [28], our analysis of cheR1 transposon mutants in the PA01 and PA14 strain background (correct insertion of transposon was confirmed by PCR) revealed a severely impaired swimming motility in minimal medium soft agar plates (Figure 3A and B).
Since insertions at both fixed and variable loci generate bands, large numbers of fixed "background" insertions (as with human Alu elements) can greatly reduce the useful genotyping capacity of a TD experiment.
In theory, most identified insertions should be oncogenic because these, and particularly the earliest events in tumourigenesis, should be present in most, if not all, tumour cells, whereas background insertions should be present in a smaller proportion of cells.
Clustering of insertions from different tumours into common insertion sites (CISs) helps to distinguish oncogenic and background insertions.
Like the mutations in human cancer, tumour DNA will contain both insertions that drive oncogenesis (oncogenic insertions) and insertions that are passengers (background insertions).
Mutants deficient in pneumolysin expression in both the encapsulated and unencapsulated background were constructed by insertion of an erythromycin cassette into the pneumolysin (ply) gene.
According to the Times, J. Douglas Carroll, Jr., the Tri-State Transportation Commission's executive director, reported that preliminary findings by acoustical experts showed that a low-level background hum inside the house allowed occupants "to operate more smoothly Insertion of such domestic background noises, tended to improve adaptability of people to aircraft noise.
DNA gel blot analysis confirmed that the transformants contained ectopic insertions of the VdGARP1-complementing construct and the original T-DNA insertion of the vdgarp1 background (Figure 4C).
We used lines in the Col-0 background, homozygous for a single-locus insertion of the transgene of interest and shown to have a positive effect on all rosette leaves or a subset of those (Cho and Cosgrove, 2000; Gonzalez et al., 2010; Spartz et al., 2012).
