摘要:Abstract: Exonic circular RNA (ecircRNA) is a class of special RNA molecule which is processed from pre- mRNA through back-to-splice. Recently, a lot of researches identified thousands of circular RNA in eukaryotes and found that circRNA could function as gene regulator. In our research, we predicted 1112 canonical circular RNAs in RNase R treated RNA-seq from different development stages of Caenorhabditis elegans. We discovered that these circular RNAs had developmental specificity, and had no obvious correlation with linear RNA. Through analyzing the sequence information of flanking introns, we inferred that circular RNAs in C. elegans were produced by intron- pair-ing-driven circularization model.
