摘要/Abstract

摘要：

环状RNA (circRNA)是一类由mRNA前体经反向可变剪切而来的共价闭合且保守的单链转录本,通过miRNA海绵功能、干扰可变剪切、结合蛋白等方式调控源基因及线性mRNA的表达。测序结果显示,circRNA广泛存在于不同的植物体内,通过细胞类型特异性表达以及组织特异性表达参与花发育、果实成熟、逆境响应等多个生命过程,在植物发育过程中发挥着重要作用。本文综述了植物circRNA的形成机制、鉴定方法、数据库、表达模式以及潜在的生物学功能,通过与动物相关研究结果的比较,概括了植物circRNA的结构特征和调控潜能,以期为植物circRNA研究提供参考。

Abstract:

Circular RNAs (circRNAs) are covalently closed, conserved single-stranded transcripts that are produced from precursor mRNA (pre-mRNA) back-splicing. They could function as microRNA sponges, interfere with splicing and bind to protein to regulate the expression of parental genes and linear mRNAs. Next-generation RNA sequencing (RNA-seq) has recently shown that the expression of circRNAs is widespread in plants. circRNAs participate in multiple biological processes such as floral development, fruit ripening, and biotic and abiotic stress responses by cell type-specific and tissue-specific expression patterns, indicating that they may play an important role in plant development. In this review, we summarize the current knowledge of plant circRNAs in recent years, including the biogenesis, detection, databases, expression pattern, and potential functions in comparison with animal results to provide new insights for functional research interests of circRNAs in the future.
