Daly and colleagues found D. radiodurans accumulates very high manganese and low iron, and proposed that Mn(II) helps it recover from radiation injury.
As reported in: Daly, Gaidamakova, Matrosova et al. (2004). Accumulation of Mn(II) in <i>Deinococcus radiodurans</i> Facilitates Gamma-Radiation Resistance. Science. doi:10.1126/science.1103185
Abstract only
Zahradka and colleagues described how D. radiodurans reassembles hundreds of genome fragments using a process they called ESDSA, followed by crossovers.
