Exome capture has rapidly become a standard practice in clinical genetics for determining the basis of human diseases , especially due to the development of various exome capture platforms that differ in terms of probe design, sensitivity, coverage and their ability to detect different types of variants (e. and Jake L. The aggregate capture data is in exome. 11%) were uniquely differentially expressed with 1 extraction method only for exome-capture and total RNA sequencing,. INTRODUCTION. 1 Library preparation and sequencing 2. , 2010 ; Vallender, 2011 ) and an assay designed for domestic cattle has. In this study, we. Current technologies enable HTS of large intervals, whole exomes and the entire genome using interval-specific array capture, exome capture and whole genome sequencing in both mice and humans. The all-inclusive Illumina kit is optimized to generate library DNA of ∼600 bp including dual indexes. These wheat lines included landraces and cultivars so as to capture the genetic diversity of the major global wheat growing regions, gaining. TruSeq Sample Enrichment Guide. Many groups have developed methodology. Using whole exome capture (WEC) developed from an early genome assembly of Chinese Spring, an expanded polymorphism discovery was performed by re-sequencing 62 diverse wheat lines [22]. picard. Exome capture and next-generation sequencing was performed by Roche NimbleGen and Roche 454 Life Science according to manufacturer's protocols. The data were generated by re-sequencing 62 diverse wheat lines using whole exome capture (WEC) and genotyping by sequencing (GBS) approaches. The panel of wheat lines was selected to capture the genetic diversity of the major global wheat growing regions and included landraces and cultivars (Figure 1b; Table S1 and Figure S1 in Additional file. Reads were mapped using the bwasw option in bwa version 0. The wheat genome is large and complex and consequently sequencing efforts are often targeted through exome capture.
