Abstract

Noncanonical (non-B) DNA structures, including G-quadruplexes, R-loops, and various DNA alternate conformations, affect genome organization, stability, and activity. Very few non-B structures have been mapped across plant genomes. Recently, Ma et al. identified intercalated-motifs (cytosine-rich, four-stranded quadruplex DNA) in rice, expanding how non-B DNA may contribute to plant gene regulation.

Keywords: G4s; R-loops; i-motifs; iMs; non-B DNA.
