sequence capture data for Salix reticulata
Leaf tissues were collected and dried on silica beads. DNA was extracted from leaf tissue using the Qiagen DNeasy Plant Minikit (Qiagen, Hilden, Germany) and fragmented using sonication with the Covaris E220 Focused Ultrasonicator (Covaris, Inc., Woburn, MA, USA). Libraries were prepared using the NEBNext Ultra II DNA Prep Kit (New England Biolabs, Ipswitch, MA, USA), and quantified using an Agilent Bioanalyzer 2100 DNA 1000 kit (Agilent Technologies, Santa Clara, CA, USA). Libraries were pooled at equimolar concentrations into sixteen pools of six prior to probe hybridization to our targeted capture baits following the Arbor Biosciences myBaits protocol v 3.0.1. The hybridized samples were subsequently pooled at equimolar ratios and sequenced at the Oklahoma Medical Research Foundation (Oklahoma, OK, USA) using a HiSeq 3000 (Illumina, Inc., San Diego, CA, USA).
