Research Progress in the Biological Functions of Plant circRNAs

doi:10.13560/j.cnki.biotech.bull.1985.2021-1586

Abstract

Abstract:

Circular RNAs（circRNAs）are covalently closed-loop single-stranded RNA molecules. As an important member of the endogenous noncoding family，circRNA has received more and more attention in recent years. circRNAs widely exist in higher eukaryotes. The studies of circRNAs have been accelerated by the combination of next generation sequencing，chemoinformatics and some other advanced technologies. Studies have shown that circRNAs are relatively stable and conserved molecules with cell-type-，tissue-，or developmental-stage-specific expression patterns. Until now，the functions of circRNAs include acting as miRNA sponges，coping with biotic or abiotic stresses and regulating parental gene transcription，etc. Here，we summarize the classification and characteristics of plant circRNAs，and highlight the progress on their biological functions and their applications as biomarkers in plant breeding and improvement of stress resistance. This article will provide a reference for the further study of circRNAs.

Key words: circRNAs, molecular characteristics, biological functions, plants
