library_construction_protocol: Total RNA was extracted using TRIzol Up ((ET111-01, Transgen)). 1.2 ug of total RNA was used for the construction of sequencing libraries.RNA quality was assessed by Agilent Bioanalyzer, with RIN values > 8.0. RNA samples were enriched for poly A species, and the sequencing libraries were constructed and then sequenced on a BGISEQ-500 platform (Beijing Genomics Institute, BGI).
