Circular RNAs (circRNAs) are a recently discovered type of non‐coding RNA derived from pre‐mRNAs. R‐loops consist of a DNA:RNA hybrid and the associated single‐stranded DNA. In Arabidopsis thaliana, circRNA:DNA R‐loops regulate alternative splicing (AS) of SEPALLATA3 (SEP3). However, the occurrence...
