Sequencing libraries were generated from an equimolar pool of 963 synthetic miRNAs (miRXplore Universal Reference) using the SMARTer smRNA-Seq Kit for Illumina (1 ng input; purple), or a small RNA-seq kit from a different vendor (Competitor N) employing an adapter ligation. When applying small RNA sequencing (smRNA-seq) for miRNA analysis using 3T3-L1 and AML12 cells, however, we found that the qPCR method identified more unique miRNAs and thus better discriminated. Over the past decade, next-generation sequencing technologies have allowed us to explore the sRNA populations with unprecedente. However, there has currently been not enough transcriptome and small RNA combined sequencing analysis of cold tolerance, which hinders further functional genomics research.
