Circular RNAs (circRNAs) are important regulatory molecules involved in various biological processes. However, the potential function of circRNAs in the turning red process of 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 leaves by regulating auxin, cytokinin, gibberellin, ethylene, and abscisic acid. This study revealed the potential role of circRNAs in the colour change of leaves.
环状RNA(circRNAs)是参与各种生物学过程的重要调控分子。然而,circRNAs在叶片变红过程中的潜在功能尚不清楚。本研究利用RNA测序数据,在四个不同发育阶段的叶片样本中鉴定出6228个circRNAs,并表明有88个circRNAs差异表达。对花青素和circRNAs进行了相关性分析。共鉴定出16个可能参与调控蒙古栎叶片颜色的circRNAs。circRNAs可能通过调节生长素、细胞分裂素、赤霉素、乙烯和脱落酸来影响叶片颜色。本研究揭示了circRNAs在叶片颜色变化中的潜在作用。
