Exome capture allows an unbiased investigation of the complete protein-coding regions in the genome. These wheat lines included landraces and cultivars so as to capture the genetic diversity of the major global wheat growing regions, gaining. picard. In preparation for higher throughput of exome sequencing using the DNBSEQ-G400, we evaluated target design, coverage statistics, and variants across these two different exome capture products.
