RNA-Seq of snail Nerita yoldii:  XM sample under 25 stress
Sequencing libraries were prepared using the NEBNext? UltraTM RNA Library Prep Kit for Illumina? (NEB, USA) with DNase treatment following manufactures recommendations and index codes were added to attribute sequences to each sample. Library quality was assessed on a 2100 Bioanalyzer (Agilent Technologies). The clustering of the index-coded samples was performed on a cBot Cluster Generation System using HiSeq 4000 PE Cluster Kit (Illumina) according to the manufacturers instructions.
