Circular RNAs(circRNAs)are endogenous non-coding RNAs with covalently closed structures,which have important functions in plants.However,their biogenesis,degradation,and function upon treatment with gibberellins(GAs)and auxins(1-naphthaleneacetic acid,NAA)remain unknown.Here,we systematically identified and characterized the expression pat-terns,evolutionary conservation,genomic features,and internal structures of circRNAs using RNase R-treated libraries from moso bamboo(Phyllostachys edulis)seedlings.Moreover,we inves-tigated the biogenesis of circRNAs dependent on both cis-and trans-regulation.We explored the function of circRNAs,including their roles in regulating microRNA(miRNA)-related genes and modulating the alternative splicing of their linear counterparts.Importantly,we developed a cus-tomized degradome sequencing approach to detect miRNA-mediated cleavage of circRNAs.Finally,we presented a comprehensive view of the participation of circRNAs in the regulation of hormone metabolism upon treatment of bamboo seedlings with GA and NAA.Collectively,our study provides insights into the biogenesis,function,and miRNA-mediated degradation of cir-cRNAs in moso bamboo.
