Functions of circRNAs in plants. (I) The processing of circRNAs can affect the splicing of their linear counterparts. (II) CircRNAs can regulate transcription of their parental genes. (III) CircRNAs can regulate the splicing of their linear cognates. (IV) CircRNAs can act as miRNA sponges. (V) CircRNAs can regulate gene expression in response to biotic or abiotic stresses. (VI) CircRNAs can be translated. (VII) CircRNAs are promising biomarkers.
