Genomic integrity is constantly challenged by transcription/replication conflicts, a major source of replication stress and instability across all life forms. While extensive studies have elucidated mechanisms for resolving transcription/replication conflicts in animals, yeast, and prokaryotes, their counterparts in plants remain largely unexplored. Through a forward genetic screen, we identified LUMINIDEPENDENS (LD), previously known for its role in regulating the flowering repressor FLC, as a key factor in mitigating replication stress in plants.
