title: bell ringer: Bx
design: Total RNA was extracted from the nematode powder using CTAB and then cleaned using an RNeasy Minikit column. The OD260 nm/OD280 nm and OD260 nm/OD230 nm values of the extracted RNA were quantied using a NanoDrop. Then, 8 cDNA libraries were prepared and sequenced by BGI-Shenzhen according to the BGISEQ-500 standard protocol.
