For these reasons, here, by combining sequence capture and target-enrichment methods with high-throughput NGS re-sequencing, we were able to scan at exome-wide level 46 randomly selected bread wheat individuals from a recombinant inbred line population and to identify and classify a large number of single nucleotide. 31–35). WES was conducted at Novogene (Sacramento, CA, USA) following Agilent’s protocols for whole exome capture and library construction. Tikhonovab, Paul Zumbob, Ahmet Nayirc, Ays in Bakkalog˘lud, Seza Ozen¨ d, Sami Sanjade, Carol Nelson-Williamsa, Anita Farhia, Shrikant Maneb, and Richard P. 0 • 96 Mb SeqCap EZ Exome Plus Probes • Customizable version of SeqCap EZ Exome v3. 6%) including non-synonymous SNPs, small indels (<10 bp), and a large UTR5/exon 1 deletion. The exome capture data from Schuster et al. In the last few years, new exome capture and sequencing technologies, particularly the Twist exome capture kit and long read sequencing (LRS) technologies, have been applied in clinical sequencing studies [20–22]. In contrast, the trascriptome varies between cell types (e. The aggregate capture data is in exome. 00 for total RNA sequencing data, respectively. this wheat skim exome capture (SEC) protocol, and sequenc-ing results at various multiplexing levels in terms of exome coverage, bait coverage, and variants identified. Array-based exome enrichment uses probes bound to high-density microarrays to capture exome. It also covers the TERT. Vcrome Rebal Exome Probes SeqCap EZ Hyb and Wash, 24 Rxn, Cat #05634261001, Roche. Each exome capture lane generated 268,972 to 367,692 clusters per tile (raw), with 82. In short, target capture can be an invaluable tool for a wide range of sequencing projects. These analyses help clarify the strengths and limitations of those data as well as systematically identify. Exome capture platforms have been developed for RNA-seq from FFPE samples.
