library_construction_protocol: RNA was extracted using TRIzol Reagent (Invitrogen#15596026) using the manufacturer's protocol with some exceptions. 100 uL of acid-washed sand (Sigma-Aldrich#27439) was added to each sample at the beginning of the extraction protocol to aid with homogenization. RNA was eluted in nuclease-free water and stored at -80C until further use. Libraries were prepared for sequencing using the NEBNext Ultra II RNA Library Prep Kit for Illumina (New England Biolabs# E7775) starting with 50ng of total RNA per sample as input and 14 cycles of PCR. Barcoded libraries were pooled and sequenced on the NovaSeq 6000 S-Prime flow cell to obtain 50bp paired-end reads.
