RNA-seq libraries were prepared using the MGIEasy RNA Library Prep Kit and sequenced on the Illumina HiSeq X Ten platform (paired-end 150 bp) by the Beijing Genomics Institute (BGI, Shenzhen, China). Raw reads were quality-checked using FastQC [50], and adaptor contamination, low-quality reads, and poly-N sequences were removed using SOAPnuke (v1.6.5)
