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.
