However, the potential function of circRNAs in the turning red process of <i>Quercus mongolica</i> leaves is unclear. This study used RNA-seq data to identify 6228 circRNAs in leaf samples from four different developmental stages and showed that 88 circRNAs were differentially expressed. A correlation analysis was performed between anthocyanins and the circRNAs. A total of 16 circRNAs that may be involved in regulating the colour of Mongolian oak leaves were identified. CircRNAs may affect the colour of <i>Q. mongolica</i> leaves by regulating auxin, cytokinin, gibberellin, ethylene, and abscisic acid. This study revealed the potential role of circRNAs in the colour change of <i>Q. mongolica</i> leaves.BiologyIdentification and Characterisation of the CircRNAs Involved in the Regulation of Leaf Colour in <i>Quercus mongolica</i>.PMC10968399KJZXSA20220X2021YFD2200302Zhou MHuang DWang QLu YXu CPang JPang XYuan YfalseIdentification and Characterisation of the CircRNAs Involved in the Regulation of Leaf Colour in <i>Quercus mongolica</i>.Circular RNAs (circRNAs) are important regulatory molecules involved in various biological processes.
