N-pool, the library created from pooled DNA from plants with no anthocyanin content; H-pool, and the library created from pooled DNA from plants with high anthocyanin content; Mapped reads rate (%), the proportion of the clean sequence reads mapped to the CM334 reference genome relative to the total clean reads; Q30, a quality score of 30 indicates 0.1% error probability or 99.9% sequence accuracy; GC, guanine-cytosine content; SLAF, specific-locus amplified fragment.
