title: Illumina seq of Dth mantle
design: The genomic DNA was extracted from the adductor muscle using the CTAB method (Stewart & Via, 1993). The genomic DNA quality was determined using agarose gel (1.0%) electrophoresis and quantified using a NanoDrop ND-1000 spectrophotometer (Thermo Scientific, USA). Genomic sequencing was conducted on an Illumina NovaSeq 6000 sequencer (Illumina, USA) in Novogene (Tianjin, China) to generate 150-bp paired-end reads.
