Transposons are mobile DNA sequences abundant in eukaryotic genomes. Non-coding small RNAs have various biological functions and affect gene expression at different levels. Transposons are an important source of non-coding small RNAs in many eukaryotic genomes. Some recent studies have found that transposons and their derived non-coding small RNAs participate important roles in gene regulation, but few relevant reviews exist in China. Therefore, this paper reviews the current research achievements on transposons and non-coding small RNAs from two aspects: the relationship between transposons and their derived non-coding small RNAs and their role in the genome and biological evolution.
