Systematic identification and characterization of circular RNAs involved in flag leaf senescence of rice

Abstract: Main conclusion Circular RNAs (circRNAs) identification, expression profiles, and construction of circRNA-parental gene relationships and circRNA-miRNA-mRNA ceRNA networks indicate that circRNAs are involved in flag leaf senescence of rice. Abstract Circular RNAs (circRNAs) are a class of 3′-5′ head-to-tail covalently closed non-coding RNAs which have been proved to play important roles in various biological processes. However, no systematic identi… Show more

“…Moreover, miRNAs, as noncoding RNAs also play a key role in regulating poplar root responses to different N forms (Zhou and Wu, 2022a). CircRNAs, as another noncoding RNA, exist widely in different tissues of plants and play a key role in plant regulation of growth and development and resistance to abiotic stress (Zhang et al, 2020;Huang et al, 2021;Li et al, 2021;Ma et al, 2021). However, circRNAs in poplar root responses to different N forms have not been reported.…”

“…It was not until the first discovery of circRNAs in Arabidopsis thaliana in 2014 [ 15 ] that research on circRNA in plants began. Since then, a large number of circRNAs have been identified in various plants, such as cucumber [ 32 ], corn [ 33 ], wheat [ 34 ], rice [ 2 ], and sweet pepper [ 19 ]. These studies revealed the essential roles of circRNAs in various biological processes in plants.…”

“…For example, it has been reported that 53 differentially expressed circRNAs in the circRNA-miRNA-mRNA network of sea-buckthorn fruits might function as the miRNA sponge in fruits development [ 35 ]. In another study of circRNAs in rice flag leaves, three networks were constructed and several key circRNAs were found to act as the miRNA sponge, which is involved in large-scale gene regulation related to leaf senescence [ 2 ]. In this study, we identified 10 differentially expressed circRNAs that can potentially bind to miRNAs, and constructed 7 circRNA-miRNA-mRNA networks.…”

“…For example, miR156, miR164, miR172, and miR840 regulate leaf senescence by suppressing their target genes ( Kim et al, 2009 ; Wu et al, 2016 , 2020 ; Tian et al, 2019 ; Yujun et al, 2019 ; Roussin-Leveillee et al, 2020 ). In addition to miRNAs, circular RNA (circRNA), and long non-coding RNA (lncRNAs) participate in leaf senescence of rice by a competitive endogenous RNA (CeRNA) network ( Huang et al, 2021a , b ). Interestingly, EIN3 and clock-associated PSEUDO-RESPONSE REGULATOR 9 (PRR9) up-regulate the transcription level of ORE1 by inhibiting the transcription of miR164 ( Li et al, 2013 ; Kim H. et al, 2018 ).…”
