design: To construct venom gland and liver tissue transcriptomes, we first extracted total RNA with TRIzol reagent (Thermo Fisher Scientific Inc., Waltham, MA, USA), following the manufactures protocol. Poly(A) mRNA enrichment was performed using a NEBNext Poly(A) mRNA Magnetic Isolation Module (New England BioLabs Inc., Ipswich, MA, USA), followed by cDNA synthesis, RNA-sequencing library preparation, and 150 bp paired-end sequencing on an Illumina HiSeq 2500 instrument.
