Résumé

Deinococcus radiodurans is able to survive under extreme conditions, including high doses of ionizing radiation, desiccation and oxidative stress. In addition to enhanced DNA repair capabilities, an effective antioxidation system plays an important role in its robustness. Previous studies have linked the radiation resistance of D. radiodurans to its prolonged desiccation tolerance phenotype, which both cause DNA damage. In the current study, we investigated the roles of dr_1172 in D. radiodurans, the gene encoding a typical group 3 LEA protein (DrLEA3) conserved within Deinococcus species. In addition to the increased transcriptional level under oxidative stress, the inactivation of dr_1172-sensitized cells to H
