title: Xinhai14
design: For each accession, we collected young leaf tissues for genomic DNA extraction using a standard cetyltrimethylammonium bromide (CTAB)-based protocol36. The genomic DNA was prepared from a single plant of each accession for sequencing. Each library was sequenced on an Illumina HiSeq2500 instrument (Illumina) to generate about 305 bp paired end reads.
