Whole exome sequencing (WES) is a targeted next generation sequencing (NGS) approach that uses modified oligonucleotide probes to “capture” and enrich the protein coding regions (exons) in a genome. important traits in a number of crop species. ( B ) Equivalent coverage was obtained for manual versus automated and plates versus tubes for libraries captured with the xGen Exome Hyb Panel v2, n =1 for each test. No call was seen upon alignment to hg38, where the genotype was confirmed also to be G/G upon reads visualization. This set of tracks shows the genomic positions of from a full suite of in-solution-capture target enrichment exome kits for Next Generation Sequencing (NGS) applications. Faster workflows from sample to data are enabled by using SureSelect QXT, the only single-day capture solution, coupled with SureCall, a guided analysis software for single sample, paired, or trio analysis. Because protein-coding exons only comprise about 1% of the genome, targeting exons—while conversely excluding other regions―can lower both the cost and time of sequencing. Coverage can also vary because of differences in exon capture between different sequencing platforms. The medical genetics community still lacks robust exome-wide information about the prevalence of small (exon-level) variants. The discovery of functional genes underlying agronomic traits is of great importance for wheat improvement. 3 Whole Exome Sequencing V4 & V4+UTR 2 QC workflow .
