Photooxidative stress stimulates illegitimate recombination and mutability in carotenoid-less mutants of Rubrivivax gelatinosus.

The EMBO journal - 1 Aug 1997

Abstract excerpt

Carotenoids are essential to protection against photooxidative damage in photosynthetic and non-photosynthetic organisms. In a previous study, we reported the disruption of crtD and crtC carotenoid genes in the purple bacterium Rubrivivax gelatinosus, resulting in mutants that synthesized caroten...
