m6A RNA modification as a new player in R-loop regulation

RNA:DNA hybrids that form across genomes control a wide range of biological processes. A new study shows that N6-methyladenosine (m6A) modification on the RNA moieties regulates the formation and genome integrity of these hybrids. This finding opens a new avenue of research on how RNA modifications (the ‘epitranscriptome’) can help control genome maintenance.
