Number of reads with at least one overlapping nucleotide mapping to either exons, introns or within 1 kb of gene boundaries.
Variable nucleotide maps of the Group variation within Categories are contained in Additional file 4.> -wrap-foot>> -wrap-foot> a blp Categories are numbered.
However, in the case of V. vinifera, for which relatively well-annotated genomic and transcriptomic data are available, the use of a nucleotide mapping reference represents a convenient technique that allows the utilisation of annotations detailed and updated on NCBI.
Although the use of a nucleotide mapping reference means the genes investigated in our analysis are determined by pre-existing transcriptomic data, the high percentage of reads mapped under high-stringency conditions indicated a high level of coverage of actual transcribed sequences.
DOI: http://dx.doi.org/10.7554/eLife.04686.010 A striking difference between our cryo-EM maps, however, is a distinct upward displacement of the P-loop away from the switch II loop in our no-nucleotide map.
Consistent with this interpretation, while the P-loop forms a visible contact with the switch II loop in our ATP analog map, a gap appears between these elements in the no-nucleotide map.
After modifying the 4HNA coordinates as described in the main text (deletion of neck-linker residues and ATP), we equilibrated this system to allow water into the newly vacated nucleotide pocket, and then introduced an cryo-EM steering potential (linear ramp over 10 ns, as was done for the ATP state model) in order to bias the coordinates toward the conformation observed in our no-nucleotide map.
However, the last 4,000 nucleotides map to human chromosome 16, which is syntenic with rhesus chromosome 20.
Furthermore, as shown in Figure 1, in all the samples over 90% and less than 10% of the total mapped nucleotides were mapped to the sense strand and intergenic regions, respectively, with only 0.35 ~ 0.95% of the total mapped nucleotides mapped to the antisense strand.
Single nucleotide polymorphism (SNP) identification in the species-specific mappings considered sequencing quality scores of the used and surrounding nucleotides, mapping depth and quantity of the rarer allele for quality control.
Single-nucleotide mapping thus complements traditional deletion and overexpression screening paradigms and opens new frontiers in quantitative genetics.
