Genome maintenance

A light switch for DNA break repair

Nature Plants volume 9, pages 1178–1179 (2023)Cite this article

Subjects

Organisms have developed specialized and intricate mechanisms to cope with environmental threats that depend on their natural habitat and ability to move. Arabidopsis demonstrates an impressive adaptation using cryptochrome 1 to maintain genomic stability through a blue-light-mediated process that involves the recruitment of repair proteins to double-strand breaks.
