The field of circular non-coding RNAs have been gradually attracted wide attention with the developments of high-throughput sequencing. In this review, we systematically summarize three driving models for circRNAs biogenesis: intron-pairing-driven, RNA binding protein-driven and lariat-driven. In addition, we also briefly introduce the current research methods of circRNAs, which include high-throughput library construction methods, identification through bioinformatics and common experimental verification. Here, we also systematically summarize the functions of circRNAs, including microRNA (miRNA) or protein sponges, regulating the alternative splicing (AS) and expression of host genes, and extensive translation. Finally, we provide a systematic characterization and the latest research progress of circRNAs, which provide a new perspective for further studies of circRNAs in plants.
Key words: circular RNAs; back-splicing; alternative splicing; sponge
